Shinjuku OP Hirose Clinic

Shinjuku OP Hirose Clinic is a small internal medicine practice tucked into the residential Kawadacho neighborhood — quieter than the Shinjuku station chaos, but still very central. This is your go-to for the bread-and-butter stuff: checkups, chronic condition management, colds that won’t quit, referrals when something needs a specialist.

English capability here is real but modest. Staff can handle a basic conversation, and there are some English-language resources on hand. You’re not going to struggle to explain a fever or ask about a prescription refill. For anything more complex — detailed symptom history, mental health, nuanced diagnoses — bring a bilingual friend or prep your notes in Japanese ahead of time.

The clinic runs under the medical corporation Seiteikai, which gives it a bit more institutional backbone than a one-person neighborhood practice. It’s not a flashy international clinic, and it doesn’t pretend to be. It’s a functional, accessible internal medicine option for expats who need reliable primary care without trekking across town.
