We strive to provide personalized medical care.

Be careful when you search us on the web!

Please be advised that our formal name of the clinic is Taiseikai Onishi Iin in Japanese. Iin means clinic. When you search for our clinic on the website, please use this formal name. We are located in Ota – ku. There is a different clinic in Shinagawa named Onishi Clinic and they don’t offer walk-in blood test.

I am sorry that our English home page shows Taiseikai Onishi Clinic. We did not realize this translation could cause confusion approximately 20 years ago when we first made the original English website.
