Best Japanese Digital Pianos 2026: Yamaha vs Roland vs Casio

This article contains promotional / affiliate links.

Want to play the piano in Japan without upsetting the neighbours? A digital piano (電子ピアノ, denshi piano) gives you 88 weighted keys, a volume knob and headphone jacks, and the best-known makers are Japanese: Yamaha, Kawai, Roland, Casio and Korg. Two of our seven picks start under ¥50,000 in Japan.

We compared current models using the makers’ Japanese spec pages, with Japanese prices from kakaku.com and US prices from US music dealers, all checked on 3 October 2026. Five of the seven had an Amazon Japan offer on kakaku.com, and US versions of all seven are sold by US dealers (why not take a Japanese one abroad? See voltage).

How to choose a digital piano in Japan

1. 88 weighted keys

For lessons, get all 88 keys with a weighted hammer action; every pick here has one (Roland and Korg say theirs feel heavier in the bass and lighter in the treble, like an acoustic piano). Polyphony, the number of notes that can sound at once, runs from 96 (Roland FP-10) to 256 (Roland FP-40) among our seven.

2. Portable or home console?

Our six portables weigh about 11 to 14 kg and are 23.2 to 33.6 cm deep, so they suit a one-room apartment, but they need a stand, sold separately (see the FAQ). Yamaha’s YDP-146 console has its own cabinet and three pedals, but weighs 38 kg and is 42.2 cm deep. Either way, measure the wall: our picks are 128.4 to 135.7 cm wide.

3. Noise: what the neighbours hear

Headphones silence the speakers, not the keys. An older rental guide on All About (last updated in 2014) points out that pedal thumps, key noise and vibration reach the flats below and next door, and says that in the rental business a “no piano” (ピアノ不可) clause is generally taken to cover digital pianos too. Rules vary by building, so read your lease (also look for 楽器不可, “no instruments”) and ask the management company before you buy; see our guide to renting in Japan and our neighbourhood rules guide. A mat can help: Roland describes its HPM-10 piano mat (no longer sold) as reducing vibration, such as key noise, transmitted to the floor.

4. Bluetooth and apps

Bluetooth audio lets you play along with music from your phone through the piano’s speakers (P-225, ES120, FP-40, YDP-146, and PX-S1100 via its included adapter). Bluetooth MIDI (FP-10, ES120, FP-40, YDP-146, and the PX-S1100 via its adapter) links apps such as Roland’s Piano Partner 2 (FP-10), Piano Sphere (FP-40) and Yamaha’s Smart Pianist (YDP-146) without a cable; the Korg B2+ uses USB-C instead.

5. Voltage: buy the version for your country

Buy the version sold where you live. In its notes on the built-in Bluetooth radio, Yamaha’s Japanese P-225 manual says the product can be used only in Japan (本製品は、日本国内でのみ使用できます), and its set-up diagram shows the adapter plugged into a 100 V outlet (AC100V). Kawai’s Japanese ES120 manual says to always use 100 V AC (電源は必ずAC100Vをお使いください), and Casio’s Japanese PX-S1100 spec lists household 100 V AC (家庭用AC100V電源). Prices are lower in Japan (PX-S1100 from about ¥44,800 vs $729.99 at US dealers, 3 October), but do not plan on using a Japanese model abroad. A proxy such as Buyee (see our guide to buying from Japan overseas) can ship one, but the boxes are bulky (145 × 37 × 26.5 cm and 18 kg for the ES120, Kawai says) and the manuals quoted above are written for Japan’s 100 V. Abroad, buy the version sold in your country, such as the US models on Amazon.com.

The 7 best Japanese digital pianos for 2026

Specs are from the makers’ Japanese pages and manuals; prices were checked on 3 October 2026 (Japan: kakaku.com; US: US music dealers such as Kraft Music). Sizes are width × depth × height.

1. Casio Privia PX-S1100 — best for small apartments

Casio calls the PX-S1100 the world’s smallest digital piano with 88 hammer-action keys, a claim it limits to depth among 88-key hammer-action digital pianos with built-in speakers (as of July 2025, Casio’s own research): it is 23.2 cm deep, 10.2 cm tall and 11.2 kg. It can run on six AA batteries (sold separately; about four hours, Casio says), and both the Japanese and US models include Casio’s WU-BT10 Bluetooth audio/MIDI adapter and a damper pedal.

Its keys and 192-note polyphony are fine for lessons; the trade-offs are modest 8 W + 8 W speakers and mini-jack headphone sockets. On sale since July 2021, it cost from about ¥44,800 (white) and ¥46,700 (black) in Japan on 3 October; Amazon.co.jp charged ¥49,219 for white and ¥59,400 for black, and US dealers $729.99.

2. Yamaha P-225 — best all-rounder

Yamaha’s mid-range portable (July 2023) samples its CFX concert grand with VRM Lite resonance and 192-note polyphony, on GHC hammer-action keys with matte black keys. Two standard headphone jacks, Bluetooth audio (receive only) and four speakers on a 7 W × 2 amplifier make it the best all-rounder here. It is 27.2 cm deep and 11.5 kg.

In Japan it costs from about ¥67,500 (Bic Camera: ¥79,200 for black on 3 October), but kakaku.com listed no Amazon.co.jp offer, so the buttons are for Amazon.com and Buyee only; US dealers charged $769.99.

Cheaper Yamaha: P-145BT (May 2025). Same GHC keys and Bluetooth audio, but AWM sampling, 64-note polyphony and one headphone jack. About ¥51,310 at Yodobashi.com (no Amazon.co.jp offer on kakaku.com) or $529.99 at US dealers (3 October 2026).

3. Roland FP-10 — best key action for the money

The FP-10 has the smallest body in Roland’s FP series (128.4 cm wide, 25.8 cm deep) but Roland’s PHA-4 Standard hammer action, the key type of the new FP-40 (pick 5) too, with escapement and moisture-absorbing ivory-feel keys, plus SuperNATURAL Piano sound. Bluetooth MIDI links it to Roland’s free Piano Partner 2 app (scores of the built-in songs, settings from your phone).

The catch: it dates from February 2019, with 96-note polyphony, 6 W × 2 speakers, no Bluetooth audio and one mini headphone jack shared with the output. In Japan it costs from about ¥62,000 (Amazon.co.jp ¥68,889); in the US it is our cheapest pick, $499.99 at US dealers.

4. Kawai ES120 — best for touch and tone

Kawai’s portable, sold in Japan as the Filo, pairs Responsive Hammer Action Standard keys with 88-key sampling of the SK-EX full concert grand, 192-note polyphony and 25 voices. It has two headphone jacks (standard and mini), Bluetooth audio and MIDI, a line out and 10 W × 2 speakers; it is 28.0 cm deep and 12.5 kg.

In Japan it costs about ¥70,000 at Yodobashi.com and Bic Camera, but kakaku.com listed no Amazon.co.jp offer on 3 October, so the buttons are for Amazon.com and Buyee only; US dealers charged $799.

5. Roland FP-40 — newest, with Wi-Fi lessons

On sale in Japan since 19 September 2026, the FP-40 is Roland’s first piano with built-in Wi-Fi, which updates the piano and links it to Piano Sphere, a lesson app made with Skoove: 100 songs and three courses are free, and a paid upgrade unlocks over 1,000 songs and lessons. It also has PHA-4 Standard keys with a triple sensor, a Piano Reality sound engine that draws on technology from Roland’s GP-series digital grands, and 256-note polyphony.

It is 33.2 cm deep and 14.0 kg with its music rest. On 3 October the lowest kakaku.com price was ¥99,000, at Amazon.co.jp among others; US dealers charged $749.99.

6. Yamaha ARIUS YDP-146 — best for children’s lessons

For a child taking lessons, a console with three pedals feels closer to an upright. Yamaha’s ARIUS YDP-146 (June 2026) has CFX sampling with VRM Lite, 192-note polyphony, GHS keys with improved sensors for faster repeated notes, damper (half-pedal), sostenuto and soft pedals, and Bluetooth audio and MIDI for Yamaha’s Smart Pianist app. The Japanese version comes with a bench and headphones and has 303 lesson songs built in; Yamaha USA says the bench may not be included, depending on the area.

At 42.2 cm deep and 38 kg, it needs a permanent spot. Amazon.co.jp listed it at ¥84,364 on 3 October (big chains ¥92,800); US dealers charged $1,299.99.

7. Korg B2+ — the budget pick for Japan

Korg’s B2+ is our cheapest pick in Japan, from about ¥43,240, with the most powerful speakers of the seven, 15 W × 2. Its NH hammer action has three touch settings, its 12 sounds include five pianos, and USB-C connects it to music apps and plays a phone’s audio through its speakers. A damper pedal and a three-month Skoove Premium trial are included.

Trade-offs: up to 120-note polyphony (fewer with some sounds), no Bluetooth, one jack shared by headphones and line out, and a 33.6 cm depth. Amazon.co.jp charged ¥53,900 on 3 October; US dealers charged $599.99.

Apartment set-up and sale tips

Setting up in a Japanese apartment

Get the landlord’s OK, put the piano on a mat and switch to headphones in the evening; two headphone jacks (P-225, PX-S1100, ES120, YDP-146) let a parent or teacher listen in. Check whether your headphones need a standard (6.3 mm) or mini (3.5 mm) plug. For lessons, the PX-S1100 (SP-34), P-225 (LP-1), FP-40 (KPD-70, with its KSF-40 stand), ES120 (F-351) and B2+ (PU-2) accept optional three-pedal units, usually fitted with the matching stand; the FP-10 takes a damper pedal only.

October sale dates

Amazon.com’s Prime Big Deal Days runs on 6 and 7 October 2026 for Prime members in the US. Amazon.co.jp’s Prime Kanshasai (プライム感謝祭) has a pre-sale on 13–15 October and the main sale on 16–19 October, also for Prime members; its point-up campaign needs an entry. Amazon has not said which pianos will be discounted.

Frequently asked questions

Can I play a digital piano in a Japanese apartment?

Check your lease first and ask the management company. An All About rental guide (last updated in 2014) said a “no piano” (ピアノ不可) clause is generally taken to cover digital pianos too, because pedal and key noise and vibration reach the neighbours. Where playing is allowed, use headphones in the evening and a mat.

Can I take a Japanese digital piano home?

Better not. Yamaha’s Japanese P-225 manual says the product can be used only in Japan, Kawai’s Japanese ES120 manual says to always use 100 V AC, and Casio’s Japanese PX-S1100 spec lists household 100 V power. Prices are lower in Japan, but buy the version sold in your own country.

Which digital piano is best for a child starting lessons?

Choose 88 weighted keys and plan for three pedals. Yamaha’s ARIUS YDP-146 has them built in, and the Japanese version comes with a bench; the Casio PX-S1100, Yamaha P-225, Roland FP-40, Kawai ES120 and Korg B2+ accept optional three-pedal units.

Do portable digital pianos need a stand?

Yes, or a sturdy table. Matching stands include Casio’s CS-68P (PX-S1100), Yamaha’s L-200 (P-225), Roland’s KSCFP10 (FP-10) and KSF-40 (FP-40), Kawai’s HML-2 (ES120, ¥15,400 including tax) and Korg’s STB1 (B2+).
