Booking a masseter Botox Tokyo clinic that actually explains dosing and brand choice in English is more important here than for almost any other injectable, because unit count varies wildly between clinics and directly determines whether you'll see results. This guide covers what Tokyo clinics actually offer for jaw slimming and bruxism relief in 2026, realistic prices in both ¥ and $, and the English-speaking clinics foreigners most commonly use.
What to Know Before Masseter Botox in Tokyo
Botulinum toxin injected into the masseter (the thick muscle you feel when clenching your jaw) gradually weakens and shrinks the muscle over several weeks, producing a slimmer, more tapered lower face and, for many patients, real relief from teeth-grinding and TMJ tension. The critical difference from cosmetic forehead Botox is volume: a forehead treatment typically uses 10 to 20 units, while masseter slimming requires 50 to 100 units total (25 to 50 per side), because the masseter is one of the strongest muscles in the body. Clinics quoting suspiciously low prices may be under-dosing or using a per-area model that hides the actual unit count, so confirming units before booking matters more here than with any other Botox treatment.
- Grinding and jaw tension typically ease within 7 to 10 days; visible jawline slimming takes 4 to 6 weeks to appear as the muscle atrophies
- Results last 4 to 6 months before a maintenance session is needed, longer than typical forehead Botox
- Short-stay visitors: cosmetic slimming won't be visible during a 1 to 2 week trip, though bruxism/TMJ relief begins within 7 to 10 days
- Patients with bruxism or naturally prominent masseters often need the higher end of the dosing range, regardless of ethnicity
- Only Botox Vista (Allergan) is MHLW-approved in Japan; Korean brands (Coretox, Nabota, Botulax) are legally used under physician responsibility but are not approved
- Always confirm which brand, how many total units, what the price includes, and whether a follow-up review is included
5 English-Speaking Masseter Botox Clinics in Tokyo
BIANCA Clinic: Omotesando
One of the few Tokyo clinics pricing Botox Vista transparently per unit rather than per area. Published English-language rates make cost comparison straightforward, and the clinic has a dedicated masseter/small-face treatment page.
English level: High: English website and multilingual staff
Price range: ¥726 to ¥770 per unit plus a ¥24,200 treatment fee; a 60-unit session totals roughly ¥67,800 to ¥70,400 ($452 to $469)
Best for: patients who want the MHLW-approved Allergan product with clear, unit-based pricing
Caveat: premium pricing compared to Korean-brand alternatives elsewhere
HADA NO CLINIC
Publishes one of the most detailed English-language masseter Botox pages in Tokyo, including a clear 50 to 80 unit recommendation and an explanation of the 4 to 6 week contouring timeline. Uses Coretox, a Korean botulinum toxin used legally under physician responsibility.
English level: High: detailed English protocol information published
Price range: not publicly indexed: request a quote at consultation
Best for: patients comfortable with a Korean-brand toxin at a likely lower cost than Allergan
Caveat: Coretox is not MHLW-approved: confirm you're comfortable with that before booking
Elm Clinic: Multiple locations (Azabujuban, Futakotamagawa, and others)
Offers an "Elabotox" facial-slimming treatment and stocks both Allergan and Korean brand options, letting patients choose between the approved product and a more affordable alternative. Multiple locations add scheduling flexibility.
English level: Moderate to high: English consultations available
Price range: per-area pricing model: confirm total unit count before committing
Best for: patients who want a choice of brand at a convenient, multi-location chain
Caveat: per-area pricing can obscure the real unit count: ask explicitly
KAI Clinic: Shibuya
Bookable through Trambellir, an English-language booking platform for Tokyo aesthetic clinics, making it easy to reserve without navigating a Japanese-only site.
English level: Moderate to high: bookable in English via Trambellir
Price range: brand and unit-count details not publicly indexed: confirm directly
Best for: patients who want the convenience of English-language online booking
Caveat: pricing and brand transparency are lower than at BIANCA or HADA NO: ask detailed questions before booking
Sakura Dental Office: Nakano
A dental clinic that also offers masseter Botox, which is particularly relevant for patients whose primary motivation is bruxism or TMJ pain rather than cosmetic slimming. A dentist administering the injection understands occlusion and bite dynamics, not just facial aesthetics.
English level: Moderate: English-speaking services listed
Price range: not publicly indexed: confirm directly
Best for: bruxism and TMJ patients wanting a dental, function-first perspective
Caveat: less geared toward cosmetic-only patients than the aesthetic clinics on this list
Masseter Botox Tokyo Price Comparison (Tokyo, 2026)
Typical 2026 price ranges for masseter Botox Tokyo patients encounter, by brand and clinic. Seoul remains a cheaper alternative at roughly $80 to $230 per session, but Tokyo offers the only MHLW-approved toxin in the market and a conservative dosing culture.
Prices are ranges across the clinics above at April 2026; confirm directly when booking. USD converted at ¥150 = $1.
