Kousen kenkyusho fuzokusinryosho
Kousen Kenkyusho Fuzoku Shinryosho is an internal medicine clinic attached to the Kousen Research Institute in Okubo, Shinjuku — a neighborhood packed with Korean restaurants and a quietly growing expat population. The clinic focuses on general internal medicine, which means it handles the bread-and-butter stuff: colds, fevers, chronic conditions, checkups.
The “foundation” setup (一般財団法人) suggests this is a more institutional, research-linked operation rather than a slick private clinic. Don’t expect a modern reception desk with English-speaking staff on standby. The website has some English-facing content, but that doesn’t mean the actual visit will be smooth in English. Bring a translation app, write down your symptoms beforehand, and have your insurance card ready. If you’re seriously ill or need nuanced communication, consider calling ahead or sending an email to test their English responsiveness before you show up.
Location-wise, you’re close to Shinjuku and Shin-Okubo stations, so access is easy from most parts of Tokyo.
Patient Feedback
Patient feedback on this clinic is limited online, especially in English. The research institute affiliation suggests a methodical, clinically serious approach rather than a warm walk-in vibe. Wait times are hard to predict without more data. Patients who’ve navigated similar foundation-run clinics in Tokyo report thorough examinations but minimal small talk — doctors focus on the medical issue, not the bedside manner. Manage your expectations accordingly.
English Language Proficiency
For translating forms, prescriptions, or discharge summaries, Jozu is worth having on your phone.
