Bangkok aesthetic clinic for Japanese patients — which branch is for you, and how Japanese-language support works

01Two branches, one medical direction

The single most common point of confusion for Japanese patients is which location they are dealing with — so here it is plainly. Waleerat operates two Bangkok branches founded and medically directed by the same physician, Dr.

Waleerat: the Siam Square One flagship and the Ekamai branch. They share the same clinical standards and brand; they differ in who they are built around.

Siam Square One is the international flagship — inside the Siam Square One mall, one minute from BTS Siam, with a multilingual concierge serving patients from across Asia, the Middle East, and the West. The Ekamai branch is the Japanese-focused location on the Sukhumvit corridor: a standalone clinic designed in dialogue with Japanese clientele, with a Japanese-speaking concierge (日本人専用窓口), Omotenashi-style hospitality, and on-site parking.

If you are Japanese and want Japanese-language support from first message to after-care, the Ekamai branch is the natural choice. If you are travelling with non-Japanese family or prefer the central Siam location, the flagship works too — the doctors and treatments are the same.

• Siam Square One — flagship, multilingual, BTS Siam, central
• Ekamai — Japanese-focused, 日本語 concierge, Sukhumvit, on-site parking
• Same founder (Dr. Waleerat), same clinical standards at both

02How Japanese-language support actually works

At the Ekamai branch, a Japanese-speaking concierge handles the parts of the journey where language matters most: understanding your goals at booking, interpreting during the doctor consultation, explaining the plan and pricing clearly, and relaying after-care instructions you can act on with confidence.

This matters because aesthetic decisions are detail-sensitive — the difference between "a little" and "natural" is a conversation, not a menu. Having that conversation in Japanese removes the guesswork.

You can also message in Japanese before arriving, so nothing important is lost in translation on the day.

03What to expect on the day

A typical visit runs: arrival and a short intake, a consultation with the doctor (with Japanese-language support at Ekamai) to agree the plan and pricing, the treatment itself, and clear after-care guidance before you leave. Most non-surgical treatments take 15–60 minutes; an online consultation beforehand keeps the in-clinic time efficient, which matters on a short trip.

If you are combining treatment with a Bangkok trip, tell the team your dates — they can sequence treatments so any swelling or bruising has time to settle before you fly home, and keep the after-care realistic for a traveller.

04What Japanese visitors choose most

Japanese patients most often ask about thread lift (PDO/PCL — non-surgical lifting), Botox for expression lines and jaw slimming, HA filler, biostimulators, and energy-based lifting such as HIFU. These are the same treatments and the same FDA-approved brands offered at both branches; the Japanese-language support simply makes choosing between them clearer.

Rather than pick from a list, the better path is a consultation: the doctor maps your goals to the right treatment and an honest expectation of what it can and cannot do. Each treatment links to its own detailed page if you want to read first.

05Booking & before you arrive

You can book through LINE chat, and message in Japanese for the Ekamai branch. Before you fly, an online photo or video consultation lets the doctor give a preliminary recommendation and rough plan, so your in-clinic time is mostly confirmation and treatment — useful on a tight schedule.

To prepare: bring records of any past treatments, note any allergies or medications, and avoid alcohol and blood-thinning supplements for a couple of days before injectables or threads (they can increase bruising). After-care instructions will be given in Japanese at Ekamai so you can follow them precisely once home.
