Tokyo Metropolitan Cancer and Infectious diseases Center Komagome Hospital

Komagome Hospital is a major Tokyo Metropolitan Government hospital in Bunkyo, specializing in cancer treatment and infectious diseases. This is a serious, high-capacity public hospital — not a neighborhood clinic. It has dedicated oncology and infectious disease departments, which means if you’ve gotten a referral for something significant, this is the kind of place that referral leads to.

The hospital has some English content on its website, but don’t expect a smooth English-first experience at reception or during consultations. This is a Japanese public hospital operating in Japanese. If you have a serious diagnosis and need specialist-level care, the clinical expertise here is real. But you’ll want to bring a Japanese-speaking friend, a medical interpreter, or at minimum a solid translation app. Walk-ins without a referral will face a surcharge and longer waits. Come prepared with documentation from a previous clinic if you have it.

Located in Bunkyo — a quieter, residential academic district — it’s accessible but not flashy. Think less “international clinic” and more “where Tokyo sends serious cases.”
