Joining a gym in Japan looks simple until you are standing at the counter holding a contract written entirely in Japanese, being asked for a bank account you may not have, and discovering that cancelling requires a visit in person before a specific date.

The gyms themselves are excellent and often cheaper than in the US, UK or Australia. The friction is entirely administrative — and almost all of it is avoidable if you know what is coming.

This guide covers what gyms actually exist in Japan in 2026, what they cost, what you need to sign up as a foreign resident, the tattoo question, and the cancellation trap that catches nearly every newcomer.

The four kinds of gym in Japan

Japanese gyms fall into four distinct categories. Choosing the wrong category is the most common mistake — people pay for a full-service club when what they actually wanted was a place to lift for 40 minutes.

1. chocoZAP — the cheapest way in

chocoZAP is run by RIZAP and has expanded to more than 1,800 locations nationwide, which makes it the most widely available gym chain in Japan. The pitch is “konbini gym”: small, unstaffed, open 24 hours, and priced so low that not going for a week does not feel like a waste.

What you should understand before joining: chocoZAP is deliberately minimal. Machines are light-to-moderate load, there are no free weights at most branches, no showers at many, and no staff to ask questions. If your goal is a serious strength programme, this is not the right choice.

If your goal is “move my body three times a week without thinking about it”, it is close to unbeatable at the price. The extras vary by branch, so check what your nearest location actually has rather than assuming.

For foreign residents specifically: the app and signup flow are Japanese-language. Registration is done online with a credit card, which removes the bank-account hurdle that trips people up at other chains. That alone makes chocoZAP the easiest gym in Japan to join as a newcomer.

2. Anytime Fitness — the standard 24-hour gym

Anytime Fitness is the most internationally recognisable chain in Japan and typically runs around ¥7,000–¥9,000 per month depending on the branch, since individual locations are franchised and set their own pricing.

The advantages over chocoZAP are real: proper free weights, squat racks, benches, showers, and staff during daytime hours. Members also get access to other Anytime locations worldwide, which matters if you travel.

The main friction is the contract. Most branches require a Japanese bank account for direct debit (口座振替), a hanko or signature, and your residence card. Some accept credit cards; many do not. Call ahead and ask specifically: “クレジットカードで支払えますか？” (Can I pay by credit card?)

3. Full-service clubs — Konami, Tipness, Central Sports

These are the large Japanese fitness clubs with pools, studios, saunas and group classes. Expect ¥9,000–¥15,000 per month for full access, with cheaper plans limited to certain days or hours.

The off-peak and daytime-only plans are genuinely good value and often overlooked — if you can train on weekday afternoons, you can cut the price substantially.

These clubs are the best option if you want a pool, want classes in a group setting, or have family members who will use it too. They are the worst option if you only lift and only go at 10pm.

4. Municipal gyms — the secret cheap option

Almost every Japanese city and ward operates public sports facilities (区民体育館, 市民体育館) with training rooms, and they are remarkably cheap: typically ¥300–¥600 per visit with no monthly contract at all.

Equipment is usually basic but functional, and many facilities also have pools and courts. Some require a short orientation session before your first use of the training room, and hours are limited compared to 24-hour chains.

For anyone who trains twice a week or less, the maths is straightforward: eight visits a month at ¥400 is ¥3,200 — the same as chocoZAP, with no contract to cancel. Search for your ward or city name plus 体育館 or スポーツセンター.

What you need to sign up

Requirements vary by chain, but this is the standard set. Bring all of it and you will not have to come back a second time.

That last one surprises people. Walking in wearing the shoes you arrived in is not acceptable at most Japanese gyms. Bring a second pair in a bag.

Tattoos: the rule nobody explains to you

This is the single most common reason foreign residents get turned away, and the rules are inconsistent enough to be genuinely confusing.

Broadly:

• Full-service clubs with pools and saunas are the strictest. Many prohibit visible tattoos outright, because the pool and bath areas follow the same conventions as public bathing facilities.
• 24-hour gyms are usually more relaxed, though some ask that tattoos be covered.
• chocoZAP is generally the most permissive, partly because branches are unstaffed and have no bathing facilities.
• Municipal facilities vary enormously by city — some have no rule at all, others follow the strict convention.

The practical advice: ask before you sign, not after. Rash guards, compression sleeves and long training tights are widely accepted as “covering”, and many gyms will approve membership on that basis even where the written rule looks absolute.

The cancellation trap

This is the part that costs people real money, and it deserves its own section.

Japanese gym contracts are typically structured so that:

• You must give notice before a cut-off date in the preceding month — commonly the 10th, 15th or 25th
• Missing that date means you are billed for another full month
• Some chains require you to cancel in person at your home branch, during staffed hours
• Phone and email cancellations are frequently not accepted
• Simply stopping payment does not cancel anything and will generate arrears

The single most important question to ask before you sign is therefore: “解約はどうすればいいですか？締め日はいつですか？” (How do I cancel, and what is the cut-off date?) Write the answer down.

This matters especially if you are leaving Japan. Plan the cancellation at least two months before your departure, and do not assume you can handle it from abroad — for many chains, you cannot.

The suspension option (休会) is widely available and widely unknown. If you are away for two months, suspending is almost always cheaper than cancelling and paying a joining fee again later.

Gym etiquette in Japan

Most of this is universal, but a few points are specific enough to be worth stating.

• Wipe down every machine after use. Towels or wipes are provided; using them is not optional.
• Bring a small towel and place it on benches before you lie down.
• Change into indoor shoes before entering the training floor.
• Do not drop weights. Deliberately dropping dumbbells or deadlifts will get you spoken to at most Japanese gyms.
• Keep noise down. Loud grunting is far more conspicuous here than in Western gyms.
• No phone photography in most facilities — locker rooms especially, but often on the floor too.
• Time limits on cardio machines (usually 20 or 30 minutes) are enforced during busy periods.

Useful Japanese for the gym

Which one should you choose?

If you are unsure, start with a municipal gym or chocoZAP. Both are low-commitment, and you will learn what you actually want from a gym before signing a twelve-month relationship with one.

Frequently asked questions

Can I join a gym in Japan as a tourist?

Monthly memberships generally require a residence card, so tourists usually cannot join. However, most municipal sports centres allow single-visit use for ¥300–¥600 with no membership, and many full-service clubs offer a one-day visitor pass for roughly ¥2,000–¥3,000. Hotel gyms are the other option.

Do I need a Japanese bank account to join a gym?

For most staffed chains, yes — they use direct debit. chocoZAP is the main exception, since registration is online with a credit card. If you have not opened a bank account yet, chocoZAP or a municipal gym are your realistic options.

Are tattoos allowed in Japanese gyms?

It depends heavily on the type. Full-service clubs with pools and saunas are strictest and may prohibit visible tattoos. 24-hour gyms are usually more relaxed. chocoZAP is generally the most permissive. Covering tattoos with a rash guard or compression sleeve is widely accepted. Always ask before signing.

How much does a gym cost in Japan?

chocoZAP is ¥3,278 per month including tax. 24-hour gyms such as Anytime Fitness typically run ¥7,000–¥9,000. Full-service clubs are ¥9,000–¥15,000. Municipal gyms charge ¥300–¥600 per visit with no monthly fee.

How do I cancel a gym membership in Japan?

Check your contract for the cut-off date — often the 10th, 15th or 25th of the month before you want to stop. Many chains require cancellation in person at your home branch during staffed hours; phone and email are frequently not accepted. Never simply stop payment, as this creates arrears rather than cancelling. If you are leaving Japan, start the process at least two months early.

What is 休会 (kyūkai)?

Suspension. Most gyms let you pause your membership for roughly ¥1,000–¥2,000 per month instead of cancelling. If you are travelling or injured for a month or two, this is almost always cheaper than cancelling and paying a joining fee again later.

Do I really need indoor shoes?

Yes, at most Japanese gyms. You are expected to change into shoes worn only inside the facility. Bring a second pair in a bag on your first visit — being turned away for this is common.

The bottom line

Gyms in Japan are good and cheap. The difficulty is never the training — it is the contract.

• Easiest entry: chocoZAP at ¥3,278/month, credit card, no bank account required
• Best for serious lifting: a 24-hour chain at ¥7,000–¥9,000
• Cheapest overall if you go twice a week: your local municipal sports centre
• Ask two questions before signing: how do I cancel, and what is the cut-off date
• Bring: residence card, indoor shoes, a small towel, and a payment method you have confirmed they accept

Get the paperwork right on day one and the rest is just training.

Leaving Japan is not one task. It is roughly fifteen small tasks spread across a ward office, a pension office, a tax office, a bank, a phone carrier, a landlord and a utility company — and several of them cannot be done once you have left. Miss the order and you will be trying to reclaim your own money from 8,000 km away, in Japanese, through a representative you no longer have.

This guide is built as a timeline, not a list. Start it about two months before your flight and work forward. Everything here applies whether you are leaving after two years on a work visa or after fifteen years with permanent residency, though the money at stake grows with the latter.

One number to anchor on before we start: the pension lump-sum withdrawal payment (dattai ichijikin) is currently capped at 60 months of contributions, and you must claim it within 2 years of losing your address in Japan. For someone on an average salary, that is a six-figure yen amount. It is the single most commonly forfeited item on this list.

The timeline at a glance

The two items people get wrong are the tax representative and the bank account. Both are decisions you make before you leave, and both determine whether you actually receive money later. We will come back to each in detail.

1. The pension lump-sum refund (脱退一時金) — the biggest number on this list

If you paid into the Japanese pension system for six months or more and you are not a Japanese national, you can claim a lump-sum withdrawal payment after you leave. You must not have met the 10-year qualifying period for an old-age pension, and you must no longer be covered by the system.

Two hard rules govern this:

• The cap is 60 months (5 years) of contributions. If you paid in for eight years, you are still refunded on the basis of five. A legal change to raise this cap to 8 years has been passed, but as of now the enforcement date has not been fixed — it is set by government ordinance within four years of the June 2025 promulgation. Until that date arrives, plan on 60 months.
• You have 2 years from the day you lose your address in Japan. Not two years from your flight — two years from the date your moving-out notification takes effect. Miss it and the money is gone permanently.

You cannot file while you are still a registered resident. The sequence is: submit the moving-out notification → leave the country → then send the claim form to the Japan Pension Service by post from abroad. Do not file early; it will be rejected.

What you need to send

The bank account must be in your own name and must accept yen transfers from Japan. This trips people up constantly. Confirm with your home bank before you leave, and get the SWIFT/BIC code plus the branch address in Roman letters while you still have time to fix problems.

2. The 20.42% you get back — but only with a tax representative

Here is the part almost nobody is told. When your pension lump-sum is paid, 20.42% is withheld as income tax on the employees’ pension (kosei nenkin) portion. That withheld amount is refundable — but only if you filed a tax representative notification (納税管理人の届出) before you left Japan.

The mechanics: you nominate someone resident in Japan — a friend, a colleague, a former employer, or a paid service — as your tax representative. After your lump-sum is paid, you send them the payment notice, and they file a tax return on your behalf to reclaim the 20.42%. The refund goes to them, and they forward it to you.

The form is submitted to the tax office covering your last address in Japan, and it takes about ten minutes. If you take one action from this article, make it this one — it is the highest return per minute of effort available to a departing resident.

Your tax representative also handles your residual resident tax if you have any outstanding, which is the next item.

3. Resident tax — the bill that follows you

Japanese resident tax (住民税) works on a one-year lag. The tax you pay this June through next May is calculated on last calendar year’s income. This means that when you leave, you almost certainly still owe tax on income you have already earned.

Crucially, liability is determined by whether you were a registered resident on 1 January. If you were resident in Japan on 1 January and leave in March, you owe the full year’s resident tax for that fiscal year — all of it — even though you will not be in the country to enjoy any of it.

Talk to your HR department early. Most companies will simply deduct the outstanding balance from your final paycheck, which is by far the cleanest option. If you are self-employed or leaving between jobs, either pay the balance in full at the ward office before departing, or have your tax representative handle it.

4. The ward office visit — do all of it in one trip

You can submit the moving-out notification (転出届) from 14 days before your departure date. Go once, and clear everything at the same counter run:

That last one is worth the extra ¥300. A copy of your removed residence record (住民票の除票) proves you no longer have an address in Japan, which is exactly what the pension claim needs. Getting it later, from overseas, is a genuine hassle.

5. Your bank account — think twice before closing it

The instinctive move is to close everything. Resist it, at least for one account.

Money can still arrive after you leave: your final salary, a deposit refund from your landlord, a utility overpayment, an insurance settlement. If your account is closed, each of those becomes a separate international problem. Meanwhile, your pension lump-sum is paid to your home country account, so it is not a reason to keep a Japanese one.

Whatever you choose, tell your bank you are leaving. Some accounts are legally tied to residency, and quietly keeping one open while non-resident can cause it to be frozen. Ask directly what their non-resident policy is; the answer varies considerably between banks.

6. Apartment, utilities and the deposit

Check your lease for the required notice period — one month is typical, two is not unusual. Give notice in writing, and keep a copy. Notice given late means paying rent for a month you are not there.

For utilities, call each provider and give them your final date. Electricity and gas usually require someone present for the gas disconnection; water and electricity are often handled remotely. Do this two weeks out, not two days.

On the deposit (敷金): Japanese practice deducts restoration costs, but there are limits. Normal wear and tear — sun-faded flooring, furniture indentations, wallpaper yellowing with age — is the landlord’s responsibility, not yours, under the national guidelines. Damage you caused is yours. If the deduction looks excessive, ask for an itemised breakdown before signing anything at the final inspection.

Take photographs of every room at handover, timestamped. It costs five minutes and is the only evidence you will have if a dispute arises after you have left the country.

7. Shipping your things home

Three routes, in rough order of cost:

The honest advice on furniture and appliances: sell them. Shipping a washing machine from Japan almost never makes financial sense, and Japanese appliances often will not match voltage or plug standards elsewhere anyway. Second-hand shops, local sale groups and community boards clear things quickly if you start a month out.

One thing to keep with you rather than ship: your pension book, tax documents, and your final payslips. You will need them for the lump-sum claim and you do not want them in a container for two months.

8. At the airport

Two things happen at immigration on your way out.

Surrender your residence card. If you are leaving permanently, you hand it in at the immigration counter. Keep a photocopy or a photo of both sides first — you will want the details for the pension claim.

Do not use the re-entry permit lane if you are not returning. Checking the special re-entry permit box on the departure card keeps your residence status alive, which sounds harmless but means you technically still hold status — and that can interfere with the pension claim, which requires that you no longer be covered by the system.

If you might return within a year on the same status, that is a different calculation and worth discussing with immigration or your employer before you fly.

The five mistakes that cost real money

1. Not filing the tax representative notification. Ten minutes of work; typically over ¥100,000 forfeited if skipped.
2. Closing every bank account. Late refunds then have nowhere to land.
3. Filing the pension claim before deregistering. It will be rejected, and by the time you find out you are abroad.
4. Forgetting the removed residence record (住民票の除票). ¥300 at the counter versus a bureaucratic ordeal from overseas.
5. Assuming the two-year pension deadline is generous. It passes faster than you think when you are rebuilding a life in another country.

Final word

Everything on this list is doable. What makes leaving Japan expensive is not difficulty — it is sequence. Several items can only be done while you are still a resident, and a few can only be done once you are not. Get the order right and the whole process is about three appointments and a stack of paperwork.

Start two months out. File the tax representative notification first, because it is the cheapest action with the largest payoff. Then work down the timeline. And whatever else you do, put a reminder in your phone for 18 months after your departure date — if the pension claim has somehow not been resolved by then, you will still have six months to fix it.

Ask any foreigner living in Japan what confused them most in their first month, and garbage sorting will be near the top of the list. Not the language. Not the trains. The garbage.

It sounds trivial until you are standing in front of six different bins at 7am, holding a plastic bottle, wondering whether the cap goes in the same bag. Then your bag gets left behind with a bright orange sticker on it, and your neighbour gives you a look you will not forget.

Here is the thing nobody tells you: there is no national rule. Japan has over 1,700 municipalities and each one sets its own system. What is burnable in Yokohama may be non-burnable in Osaka. This guide gives you the framework that applies almost everywhere, then shows you how to find your own city’s exact rules in about five minutes.

The categories you will meet almost everywhere

The critical distinction for newcomers is between プラ (plastic packaging) and ペットボトル (PET bottles). They are not the same category. A plastic yoghurt tub and a plastic drink bottle usually go in different bags.

The PET bottle ritual (three steps, every time)

PET bottles are the one item where nearly every municipality agrees, and where nearly every newcomer gets it wrong.

1. Remove the cap — the cap is a different plastic. It goes with プラ, or in a dedicated cap collection box
2. Peel off the label — also プラ. Most labels have a perforated line to make this easy
3. Rinse the bottle and crush it flat if your city asks for it

Yes, it feels excessive. But this is why Japan’s PET recycling rate is among the highest in the world — the material arrives at the plant already clean and separated.

How to read the symbols on packaging

Japanese packaging is labelled, and once you can read four marks you can sort almost anything.

When packaging has no mark at all, it usually goes in burnable — but check your city guide, because this is exactly where local rules diverge.

Items that trip people up

Oversized waste (粗大ゴミ): the paid system

Anything roughly over 30cm — furniture, suitcases, bicycles, futons — cannot go out with normal rubbish. It requires a booking and a fee.

1. Call or book online with your city’s 粗大ゴミ centre. Many now accept online applications
2. You are told a price and a collection date, typically ¥300–¥2,000 per item
3. Buy a 粗大ゴミ処理券 (sticker) at a convenience store for that amount
4. Write your name or reference number on the sticker and attach it to the item
5. Put it out at the specified place by the specified morning

📌 Booking can take 1–3 weeks in busy periods, especially March when everyone moves house. If you are leaving Japan, start this process a month before your flight.

Four appliances that are illegal to throw away

Under Japan’s Home Appliance Recycling Law, four categories cannot be disposed of as oversized waste at all:

• Air conditioners
• Televisions
• Refrigerators and freezers
• Washing machines and clothes dryers

These must go back through a retailer or a designated collection point, and you pay a recycling fee plus transport. If you bought the item in Japan, the shop that sold it is obliged to take it back. Leaving one on the street is illegal dumping and carries serious penalties.

The rules that are not about sorting

Sorting correctly is only half of it. These are the unwritten rules that actually cause friction with neighbours.

Put it out on the morning, not the night before

Most collection points want rubbish out by 8:00am on the day, not the evening before. Putting it out at night invites crows and cats, and in many buildings it is explicitly forbidden. This is the single most common complaint against foreign residents.

Use the designated bag

Many cities require specific coloured or printed bags, sold at supermarkets and convenience stores. In those cities, a normal shopping bag will simply be refused. Check whether your city uses 指定袋 (shitei bukuro).

Use the net

Collection points usually have a yellow or blue net. Put your bag under it. It exists to stop crows, and crows in Japan are formidable. A torn bag spread across the pavement becomes your responsibility.

If your bag is rejected

A sticker on your bag means it was not collected. Take it back inside, fix the problem, and put it out on the next correct day. Leaving it there is what turns a small mistake into a neighbourhood dispute.

How to find your own city’s rules in five minutes

1. Search “[your city name] ゴミ 分別 外国語” or “[city name] garbage guide English”
2. Look for the 市役所 / 区役所 official site — most publish a PDF guide in 5+ languages
3. Download the collection calendar for your district. Days differ street by street
4. Check whether your city has an app — many now offer one with notifications and a searchable item database
5. Ask at your building. Many apartments post the rules by the bins in Japanese and English

If you cannot find anything, go to your city hall in person and ask for the ゴミ分別ガイド. Staff at the residents’ counter deal with this constantly and will hand you a booklet.

A practical setup for your home

The system only works if sorting is easier than not sorting. What works for most people:

• Three bins minimum in the kitchen: burnable, plastic, PET/cans
• A bag on a hook for plastic packaging — it is bulky but light
• A box by the door for paper and cardboard
• The calendar on the fridge, with collection days circled
• Rinse as you go — a container washed immediately takes 5 seconds, one left for three days takes five minutes

Final thoughts

Japanese garbage sorting looks obsessive from the outside. Living with it for a while, most people come to see the logic: the burden is shifted to the household so that the recycling stream stays clean, and the result is one of the highest material recovery rates in the world.

You will get it wrong at first. Everyone does, including Japanese people who move between cities. Learn your local calendar, put things out in the morning, use the net — and the rest sorts itself out.

The invisible ingredient behind almost every Japanese dish

You can buy the right soy sauce, the right miso and the right rice, and your Japanese cooking will still taste flat. The missing element is almost always dashi — the light, savoury stock that sits underneath miso soup, simmered dishes, noodle broths, tamagoyaki, and the dipping sauce for tempura.

Dashi is where Japanese food gets its umami. And unlike a French stock that simmers for hours, a proper dashi takes about fifteen minutes — or thirty seconds if you use a pack.

This guide explains the main types of dashi, what to buy, how to make it from scratch, and which shortcut products are worth your money.

The four building blocks

The most common combination — awase dashi — is kombu plus katsuobushi. Kombu brings glutamates, katsuobushi brings inosinates, and the two together produce far more umami than either alone. This synergy is not folklore; it is the reason the pairing became standard.

How to make dashi from scratch

Ichiban dashi (first brew) — for clear soups

The result is pale gold and delicate. Use it where the dashi is the star: clear soup (suimono), chawanmushi, or a simple miso soup.

Niban dashi (second brew) — do not throw away the solids

Put the used kombu and katsuobushi back in a pot with 500ml of water, simmer gently for about 10 minutes, and strain. The result is stronger and less refined — perfect for simmered dishes, nikujaga, and anything with soy sauce and mirin where subtlety would be lost anyway.

Making niban dashi is standard practice in Japanese home kitchens. It halves the effective cost of your ingredients.

Kombu dashi — the vegan version

Simply soak 10g of kombu in 1 litre of cold water overnight in the fridge. That is the entire method — no heat required. Add dried shiitake to the same jar and you get a fuller, rounder vegan stock with real depth.

The shortcuts: what Japanese households actually use

Here is the honest truth that recipe blogs rarely admit: most Japanese homes do not make dashi from scratch on a weekday. They use packs or granules, and the results are genuinely good.

Dashi packs (だしパック) — the best balance

Teabag-style sachets containing ground kombu, katsuobushi, niboshi and sometimes shiitake. Drop one in simmering water for 3–5 minutes, remove, done. This is the shortcut worth adopting.

Quality varies enormously. Look for packs where the ingredient list is just dried fish and seaweed. Cheaper packs add salt, sugar and MSG, which is not a crime but removes your control over seasoning. If the pack is already salty, your miso soup will end up too salty.

Granulated dashi (顆粒だし) — fastest, most compromised

Powder you dissolve directly in hot water. Hondashi is the ubiquitous brand. It is fast, cheap, consistent and contains salt and MSG. Millions of excellent bowls of miso soup are made with it every day.

Use it when speed matters. Just remember it is pre-salted — reduce the miso or soy sauce accordingly.

Liquid concentrate (だしつゆ / めんつゆ) — different thing entirely

Mentsuyu is dashi already seasoned with soy sauce, mirin and sugar. It is not a substitute for plain dashi — it is a finished sauce base. Brilliant for noodle dipping sauce, donburi and simmered vegetables. Wrong for clear soup.

Note for readers avoiding alcohol: mentsuyu almost always contains mirin, and many contain added alcohol. Plain dashi packs and kombu dashi do not. Check the label if this matters to you.

What to buy: a starter shopping list

If you are buying one thing to take home from Japan, make it a box of good dashi packs. They are light, flat, shelf-stable and instantly upgrade every Japanese dish you cook.

Storage: the mistake that wastes good ingredients

The ice cube trick is worth adopting: make a litre of dashi on Sunday, freeze it in cubes, and you have single-portion stock ready all week.

Three dishes to make with your first batch

Miso soup (the two-minute version)

Heat 400ml dashi. Add whatever you have — tofu cubes, wakame, thinly sliced spring onion. Turn off the heat, then dissolve about 2 tablespoons of miso through a ladle or strainer. Never boil miso after adding it; boiling destroys the aroma. Serve immediately.

Ohitashi (blanched greens in dashi)

Blanch spinach or komatsuna, squeeze out the water, cut into 4cm lengths. Soak in 200ml dashi with a tablespoon of soy sauce for 20 minutes. Top with katsuobushi. This is the dish that makes people realise dashi is not just for soup.

Tamagoyaki (rolled omelette)

Three eggs, 3 tablespoons dashi, a teaspoon of sugar, a splash of soy sauce. The dashi is what makes a Japanese rolled omelette silky rather than rubbery. Cook in thin layers in a rectangular pan and roll each one forward.

Dashi FAQ

Is dashi vegan?

Katsuobushi and niboshi are fish, so standard dashi is not. Kombu dashi and kombu-shiitake dashi are fully vegan and widely used in shojin ryori (Buddhist temple cuisine). Vegan dashi packs are also sold in Japan — look for 昆布 and 椎茸 on the ingredient list with no 鰹.

Is dashi gluten free?

Plain dashi from kombu and katsuobushi is. But many granulated and liquid products contain soy sauce, which usually contains wheat. If you need gluten-free, make it yourself or read labels carefully.

Can I substitute chicken stock?

You can cook with it, but the dish stops being Japanese in character. Chicken stock is heavier and fattier; dashi is light and clean. If you have no dashi, a kombu-only stock made from a piece of kelp in cold water is closer than any Western stock.

Why does my dashi taste bitter or fishy?

Three usual causes: you boiled the kombu, you squeezed the katsuobushi when straining, or you simmered the katsuobushi too long. Dashi wants gentle heat and short contact time.

How much does homemade cost per litre?

Roughly 10g kombu and 25g katsuobushi per litre. At Japanese retail prices this is a modest amount per litre — and if you make niban dashi from the same solids, the effective cost roughly halves.

Can I buy the ingredients outside Japan?

Yes. Kombu, katsuobushi and dashi packs are all available from Japanese grocers, Amazon in most countries, and via proxy services for the specialist brands. Because everything is dried, shipping is light and customs is generally straightforward — though some countries restrict fish products, so check your local rules before ordering katsuobushi or niboshi.

Start here

If you take one thing from this guide: buy a box of good dashi packs, and make ohitashi once. The packs will carry your everyday cooking, and the ohitashi will show you what dashi actually tastes like when it is not hiding under miso.

From there, making ichiban dashi from scratch on a weekend stops feeling like a project and starts feeling like fifteen minutes well spent.

The one piece of Japanese furniture that ruins winter everywhere else

Ask anyone who has spent a winter in Japan what they miss most, and a surprising number will say the same thing: the kotatsu. A low table with a heater fixed underneath, draped in a heavy quilt, with a tabletop pressed on top to hold everything in place.

It sounds almost primitive next to central heating. It is also, once you have experienced it, extremely difficult to give up. Japanese homes are traditionally heated by room rather than centrally, and the kotatsu is the logical conclusion of that philosophy: do not heat the room, heat the person.

This guide covers what a kotatsu actually is, the sizes and heater types available, what it costs to run, the voltage problem you must solve before importing one, and how to buy from outside Japan.

What exactly is a kotatsu?

A modern kotatsu is three separate items that work together:

You sit on the floor — usually on a zaisu (legless chair) or cushion — and slide your legs underneath. The quilt keeps the warm air in. Your upper body stays in the cool room air, which is precisely why a kotatsu feels comfortable rather than stuffy.

Many kotatsu frames are designed to be used year-round: remove the futon in spring and you have an ordinary low table.

Choosing a kotatsu: six decisions

1. Size

Kotatsu are sold by tabletop dimensions in centimetres. The common sizes and who they suit:

A crucial point: the futon must be much larger than the table. A 120 × 80 cm frame typically needs a futon around 200 × 190 cm or larger so it drapes properly to the floor on all sides. Buying a futon that is too small is the single most common mistake.

2. Heater type

Older kotatsu used quartz or halogen heaters that glowed orange and ran hot. Almost all modern units use a flat carbon or graphite heater, which is thinner, more even, quieter and does not intrude on legroom.

If you are buying new, choose a flat carbon heater. If you are buying second-hand and see a bulky orange-glowing element, expect less legroom and a higher running temperature.

3. Height

Standard kotatsu sit around 36–40 cm high — floor-seating height. Some models offer adjustable legs or extension blocks that raise the table to roughly 55–65 cm so you can use it with a low sofa or a proper chair. If sitting on the floor is uncomfortable for you, look specifically for a “ハイタイプ” (high type) model.

4. Shape

Rectangular is the default. Square suits smaller rooms and even seating. Round kotatsu exist and are wonderful for conversation, but round futons are harder to find and more expensive.

5. Power and voltage — read this before you order

This is the part that catches people out. Japanese kotatsu are built for 100V, 50/60Hz, with a Japanese Type A plug. Most of the world is not.

A kotatsu heater typically draws 300–600W. If you need a transformer, buy one rated at least 1.5× the heater’s wattage — so a 500W kotatsu wants a 750W or 1000W transformer. Using a simple plug adapter on 230V mains will destroy the heater and is a genuine fire risk.

Some sellers outside Japan offer kotatsu with heaters rewired for local voltage. If you are not comfortable with transformers, that is the option to look for.

6. Running cost

This is the pleasant surprise. Because a kotatsu heats a small enclosed space rather than a whole room, it is one of the cheapest heating methods available. Most units draw 300–600W at maximum but cycle on and off via a thermostat, so average consumption is far lower — commonly quoted around 100–200W in steady use.

For comparison, an air conditioner heating a living room can draw several times that continuously. This is exactly why kotatsu remain popular in Japan despite modern heating being widely available.

What to buy: the three-part shopping list

The frame with heater

Look for a flat carbon heater, a temperature control dial, and a size that matches your room. Japanese-made wooden frames in 105 × 75 cm and 120 × 80 cm are the easiest to find internationally. Expect roughly $150–400 depending on size and finish.

The kotatsu futon (quilt)

Sold separately in most cases. Check the recommended table size printed on the product. Thicker is warmer but harder to store; a “薄掛け” (usugake, thin) futon is easier to live with in a small apartment and still perfectly warm.

Many sets include a shikibuton — a rug that goes under the whole assembly. On a hard floor this matters more than people expect: it insulates from below and stops the heat draining into the floor.

Floor seating

A zaisu (legless chair with a back) transforms the experience if you are not used to sitting on the floor. Cheaper alternative: a firm floor cushion (zabuton). Your back will thank you within the first week.

Living with a kotatsu: what nobody tells you

The dehydration point deserves emphasis. Sleeping under a kotatsu all night is a common cautionary tale in Japan — you wake up dried out, stiff and unrested. Set an alarm if you are prone to dozing off.

Buying from outside Japan

There are three realistic routes, and they suit different budgets.

A practical strategy: buy the frame locally if a decent one exists, and use a proxy for the futon. Frames are bulky and expensive to ship; futons compress well and the Japanese selection is far better in both pattern and quality.

If you are currently living in Japan and plan to move abroad, buying here and shipping with your household goods is by far the cheapest route. Just remember the voltage issue at the other end.

A cheaper alternative if you cannot commit

Not ready for a full kotatsu? Two options exist:

Kotatsu heater units are sold separately. If you already own a low table, you can bolt a Japanese heater unit to the underside. This is a common upgrade in Japan and dramatically cheaper than a complete set.

A heated blanket plus a low table gets you perhaps 70% of the experience for a fraction of the price, and sidesteps the voltage problem entirely if you buy locally. It is not the same, but it is warm.

Kotatsu FAQ

Is it safe to leave on overnight?

Modern units are thermostat-controlled and designed for extended use, but the manufacturers still recommend switching off when unattended. The bigger risk is not fire but dehydration if you sleep under it.

Can I use it on carpet?

Yes, and it works well — carpet insulates from below. On hard flooring, add a rug or the dedicated shikibuton for noticeably better heat retention.

How do I wash the futon?

Check the label. Many modern kotatsu futons are machine washable in a large-capacity machine or at a coin laundry. Thicker traditional ones usually need professional cleaning. Airing them in the sun every few weeks does most of the work.

Does it work in a small apartment?

Extremely well — this is arguably its ideal environment. A 75 × 75 cm kotatsu fits in a studio, doubles as your dining and work table, and costs far less to run than heating the whole room.

What do I do with it in summer?

Remove the futon and the tabletop sits directly on the frame, giving you a normal low table. Store the futon compressed in a vacuum bag. This year-round usability is a big part of why kotatsu remain standard in Japanese homes.

Will it heat the whole room?

No, and that is the point. A kotatsu heats the space under the quilt. In a cold climate you will still want a room heater for your upper body — the two work well together, and the kotatsu lets you keep the room heater at a lower setting.

The verdict

A kotatsu is not efficient in the sense of warming a house. It is efficient in the sense of warming the person, cheaply, in the exact spot where they actually are. For anyone in a small apartment, or anyone who spends winter evenings at a table reading, working or eating, it is one of the best-value pieces of furniture in existence.

Sort out the voltage first, buy a futon that is bigger than you think you need, and accept that your productivity in January is now negotiable.

Choosing where to live is one of the biggest decisions you’ll make as a foreigner in Tokyo. The right neighborhood can mean an easy commute, English-friendly services, great food, and a community that helps you settle in fast. This 2026 guide breaks down the best areas of Tokyo for foreigners — from international hubs to affordable local gems — with honest notes on vibe, rent, and who each area suits best.

How to Choose the Right Tokyo Neighborhood

Before falling for a name, weigh these five factors: commute (aim for one train line to your work/school), rent (central wards cost far more), English-friendliness (some areas have far more bilingual clinics, shops and neighbors), lifestyle (nightlife vs. family calm), and foreigner-friendly landlords (some agencies specialize in helping non-Japanese renters). Tokyo is huge and safe almost everywhere, so you can prioritize what matters most to you.

The Best Areas of Tokyo for Foreigners in 2026

Minato (Azabu, Roppongi, Hiroo)

The most international part of Tokyo. Home to embassies, international schools, and countless bilingual restaurants and clinics. Roppongi is nightlife central, while Hiroo and Azabu are calmer and upscale. Expensive, but unbeatable if you want an English-friendly bubble.

Setagaya (Sangenjaya, Shimokitazawa)

Tokyo’s most popular residential ward, loved for its leafy streets and village feel. Shimokitazawa is a hip haven of vintage shops and cafés; Sangenjaya offers a lively local vibe a few minutes from Shibuya. Great balance of convenience and calm.

Meguro & Nakameguro

Stylish and green, famous for the cherry-blossom-lined Meguro River, boutique cafés and a refined but unpretentious feel. Well connected yet quieter than Shibuya. A favorite of design-minded expats.

Nakano & Koenji

Just west of Shinjuku, these areas offer serious value: cheaper rent, incredible food, subculture (Nakano Broadway for anime, Koenji for live music and vintage). Fast access to central Tokyo without the central price tag.

Kichijoji & Musashino

Consistently voted one of the most desirable places to live in Tokyo. Bordered by the beautiful Inokashira Park, with great shopping and a friendly, community feel. A little further out, but the quality of life is exceptional.

Shinjuku & Shin-Okubo

For those who want to be in the center of it all. Shinjuku offers unbeatable transport connections, while neighboring Shin-Okubo is Tokyo’s multicultural district with Korean, Nepalese, and other international communities and grocery stores.

Kita & Adachi (Akabane, Kita-Senju)

If budget is your priority, northern wards deliver spacious apartments for much less, with surprisingly good transport. Kita-Senju and Akabane are lively, down-to-earth hubs that many expats discover as hidden value.
