Onishi Clinic
Onishi Clinic is a neighborhood internal medicine practice sitting in Oi, one of Shinagawa’s quieter residential pockets. This is a general adult medicine clinic — think blood pressure management, diabetes follow-ups, colds that won’t quit, and routine checkups. Not a flashy international hospital, just a solid local doctor’s office that handles the everyday stuff.
The website has some English-language content, which suggests they’ve thought about non-Japanese patients at least a little. But don’t walk in expecting a fully bilingual experience. Reception is likely Japanese-only or close to it. If your Japanese is limited, bring a translation app, have your symptoms written out, or bring a Japanese-speaking friend. The doctor may have some English ability — it’s genuinely unclear.
Good for: expats who are comfortable navigating with minimal Japanese or have a helper. Less ideal if you need detailed back-and-forth medical conversation in English without any support.
Shinagawa is well-connected, so getting there isn’t the problem. The language barrier is the real variable here.
Patient Feedback
Patient feedback on Onishi Clinic is limited in English-language sources. As a small neighborhood internal medicine practice, it likely runs with shorter wait times than larger hospitals — a genuine advantage for routine visits. The setup is typical for a Japanese solo or small-group clinic: efficient, no-frills, and focused on getting you in and out. Expect a practical, clinical atmosphere rather than a warm hand-holding experience. Nothing flashy, but that’s not what this kind of clinic is for.
