The Onishi clinic was established in the Asakusa area (central part of Tokyo) as a clinic for internal medicine in 1890. In 1930, the clinic moved to the Omori area, the more southern part of Tokyo, and set up new department of dermatology. Our operation is now extended to laser surgery and cosmetic dermatology. Our intention is to offer the newest and the most adequate medical treatment for all patients.We take good care to create a home-like atmosphere when you come for a medical examination.

Topics about laser treatment

  • Laser treatment for nevus and angioma :
    Recent laser devices can treat various kinds of congenital marks including : bluish mark (Nevus of Ota, Blue nevus, mongolian spot), brownish mark (Nevus spilus, Cafe au lait spots, Becker's nevus), reddish mark (Portwine stain, Strawberry mark) and black coloured mark (Nevus cell nevus). We started laser treatment in 1989 and have removed thousands of marks.
    This treatment was approved as an "advanced medical technology" by The Japanese Ministry of health and Welfare in 1993. From 1996, almost all of laser treatment against congenial mark was programmed under coverage of The National Health Insurance in Japan. (Telangiectasia, not a congenital mark, is also covered.) We use a Q-switched Ruby laser, Long pulsed Ruby laser, Pulsed Dye laser, CO2 laser, Unipulsed CO2 Laser and a Erbium YAG laser equipments.
