This article contains promotional / affiliate links.

Walk into any Japanese drugstore, such as Matsumoto Kiyoshi, Sundrug or Don Quijote, and you will find a whole wall of toothbrushes. Many visitors notice that the heads are small, the bristles very fine.

This guide is only about manual toothbrushes, interdental brushes, floss. It explains the Japanese words on the packs, what to check, then 7 products sold in Japan with prices checked on 11 November 2026. There is no ranking, and we did not test them. Facts come from the makers’ own pages, from Japanese local government health pages.

Why Japanese toothbrushes look different

Japanese makers sell the same brush in several head sizes, several hardness levels. Lion, one of the biggest makers, says on its システマ, Systema, page that a brush that is too big or too small cleans less well: 「ハブラシは大きすぎても小さすぎても清掃効果が低くなってしまいます。」 Makers often say a thin, compact head reaches the back of your back teeth more easily. Lion says the head of its クリニカアドバンテージ brush is only 2.6 mm thin.

The other point is the bristles. Many Japanese brushes use extra-fine bristles, or bristles with tapered tips, which get thinner toward the end. Makers say these reach into the gap where the tooth meets the gum, 歯周ポケット.

Japanese words on toothbrush packs

Most packs are only in Japanese. These are the key words to look for:

How often should you change your toothbrush?

Lion’s Clinica page suggests changing your brush about once a month. A leaflet from the Tokyo Metropolitan Government health bureau, 東京都保健医療局, explains why: as you use a brush, the bristles lose their spring, so it removes less dirt. It also says to replace it when the bristles spread out, even before one month: 「1 か月未満であっても、歯ブラシの毛先が開いてきたら交換しましょう。」

The same leaflet says that if the bristles spread out within one to two weeks, you may be brushing too hard, and suggests asking your dentist. If your gums bleed or hurt, see a dentist rather than just changing brushes.

5 toothbrushes to look for

Three popular drugstore brushes, a wide-head brush, then a gift-style brush.

1. ライオン クリニカアドバンテージ ハブラシ (Lion Clinica Advantage)

Clinica is one of Lion’s main oral care brands. Lion says the Advantage brush has a head only 2.6 mm thin, made to reach behind the back teeth. It comes in five head types. The 3-row head has a slim shape for brushing one tooth at a time; the 4-row head has a tapered shape for deep areas. The bristles are called 弾力フィット毛, springy bristles that fit into gaps. The slim six-sided handle is made for holding like a pen. There is no firm version.

2. ライオン システマハブラシ A41 (Lion Systema)

Systema is Lion’s brand for the gum line. Lion says its 超極細毛, super-fine bristles, go into the gap between tooth and gum without force, to remove plaque there. The A41 is the extra compact, 4-row, medium version. Other codes give other sizes: A31 compact, A21 regular, B31 a slim 3-row head. The しっかり毛腰タイプ, D-series, has stiffer bristles, in medium plus firm. The code is printed under the handle.

3. サンスター ガム・プラス デンタルブラシ #366 (Sunstar GUM Plus)

GUM is Sunstar’s gum-care brand. The GUM Plus series is aimed at the line where teeth meet gums. Sunstar suggests it for people who notice changes in their gums, or find food often stuck between teeth. The bristles are springy, 弾力毛, with extra-fine tips, 極細. The neck is long to reach the back teeth, and the straight handle is made for a pencil grip, エンピツ持ち.

4. エビス プレミアムケアハブラシ 6列コンパクト B-3600M (EBISU Premium Care)

EBISU is a Japanese toothbrush maker known for wide heads with many rows. This one has 6 rows, 54 tufts. The product page says it mixes 超先細毛, very tapered bristles with 0.01 mm tips for the gum line, with flat bristles for the tooth surface. The outer bristles are softer, to be gentle on the gums. The head is about 25% thinner than the maker’s older model. Made in Japan. The maker asks you to brush gently, then change the brush when the bristles spread out.

5. 夢職人 MISOKA (Yumeshokunin Misoka)

MISOKA is a Japanese toothbrush that is often sold as a gift. The maker, 夢職人, Yumeshokunin, calls it 「水だけで磨ける歯ブラシ」, a toothbrush you can use with just water. Each bristle tip has a coating of nano-size minerals. The product page says to dip the brush in a cup of water before brushing. These are the maker’s own claims; we did not test them.

Two more brands you will see: Kao’s ピュオーラ ハブラシ, Pure Oral, costs about ¥225 at Yodobashi.com, but we could not reach Kao’s page to check details. Lion also sells DENT.EX brushes, a line for dental clinics, and some are sold in shops, for example DENT.EX システマ genki at ¥440.

2 interdental brushes, all 7 compared

A toothbrush does not reach well into the gaps between teeth. For these gaps Japanese shops sell 歯間ブラシ, small brushes on a wire or rubber stick, plus デンタルフロス, floss. Edogawa City in Tokyo says on its health page that interdental brushes come in sizes, so you should ask a dentist or dental hygienist which thickness and method suit you: 「自分にあった太さと使い方を歯科医師・歯科衛生士にご相談下さい。」

Interdental brush sizes

Sizes use letters. Sunstar’s GUM packs also add a number:

※ GUM L字型 sizes. Sunstar says its sizes follow a voluntary industry standard, 日本歯ブラシ工業組合, while SSSS is its own standard. Exact gap sizes in mm were not confirmed.

Sunstar’s advice: choose the size that moves without resistance, 無理なく動かせるサイズ. If even SSSS will not go in, use dental floss instead.

6. 小林製薬 やわらか歯間ブラシ 極細タイプ SSS-S (Kobayashi soft interdental brush)

Kobayashi Pharmaceutical sells this under its 糸ようじ, Ito-yōji, floss brand. It is a rubber type, ゴムタイプ, with no metal wire. The maker says the thin tip goes into narrow gaps, and the rubber is gentle on gums. This 極細タイプ, extra-thin type, is meant for people who use SSS, SS, S wire brushes. Other packs: SSSS-SS, SS-M, M-LL.

7. サンスター ガム・歯間ブラシ L字型 (Sunstar GUM interdental brush, L-shape)

A wire interdental brush with an L-shaped handle to reach the back teeth. Sunstar says it uses triangular bristles, 三角毛, to scrape plaque, with antibacterial wire. You can wash it, use it again. Each size is sold in its own pack, from SSSS, size 0, to L, size 5.

Prefer floss? Kobayashi’s 糸ようじ フロス&ピック, floss on a plastic holder, costs ¥638 for 60 at Yodobashi.com.

Where to find them

Toothbrushes are in the oral care aisle, オーラルケア. Interdental brushes, floss usually hang next to them. One brand’s brushes hang side by side in different sizes, so read the small label on each pack. For tips on finding things in Japanese drugstores, see our drugstore shopping guide.

Can I buy toothbrushes tax-free?

Since 1 November 2026, Japan uses a refund method. According to the Japan Tourism Agency, 観光庁, you pay the full price with tax, and the tax comes back after customs confirms the goods when you leave Japan. You need to spend at least ¥5,000 before tax in one shop on one day. At departure you use a tax-free terminal with your passport, within 90 days of buying. You must have all the goods with you, so do not put them in checked baggage first. If one item on a receipt is missing, nothing on that receipt is refunded.

The agency says consumable goods such as food, drinks, cosmetics that are used in Japan cannot be refunded. Toothbrushes are not named on that page, so keep tax-free brushes unopened. Brushes cost ¥200 to ¥400, so you would need other goods from the same shop to reach ¥5,000. Read more in our Japan tax-free shopping guide.

Japanese toothbrushes come in many head sizes, hardness levels. Read three words on the pack: the head size, such as 超コンパクト, the bristles, such as 極細毛, plus the hardness, やわらかめ / ふつう. For a small head, try Lion’s クリニカアドバンテージ, Lion’s システマ or Sunstar’s GUM Plus #366, all about ¥220 to ¥280. For a wide head, there is EBISU’s 6-row プレミアムケア. For a gift, there is MISOKA.
