If there’s one thing I’ve noticed working with expats in Tokyo over the past five years, it’s that cancer screening is almost always the last thing on their healthcare checklist. People sort out their health insurance, find a GP, maybe even get a dentist — but preventive cancer checks tend to fall through the cracks. That’s a real shame, because Japan actually has one of the most accessible cancer screening systems in the world, and as a foreigner living here long-term, you’re entitled to more of it than most people realize.
This guide walks you through everything you need to know about cancer screening in Japan for expats: what’s available, what it costs, where to go, and how to actually use the system without getting lost in the paperwork.
What Cancer Screenings Are Available in Japan?
Japan’s national cancer screening program covers five major cancer types. As of 2026, these are:
– Stomach cancer (胃がん / igan) — recommended from age 50, every two years
– Lung cancer (肺がん / haigan) — recommended from age 40, annually
– Colorectal cancer (大腸がん / daichougan) — recommended from age 40, annually
– Breast cancer (乳がん / nyuugan) — recommended for women from age 40, every two years
– Cervical cancer (子宮頸がん / shikyuukeigan) — recommended for women from age 20, every two years
These screenings are subsidized by your local municipal government — meaning the ward or city office where you’re registered. If you’re enrolled in National Health Insurance (国民健康保険 / Kokumin Kenko Hoken), you’re eligible to access these at heavily discounted rates, sometimes as low as ¥500 to ¥1,000 per test.
Employer-sponsored insurance (社会保険 / shakai hoken) works slightly differently. Many companies run annual health checkups called 定期健康診断 (teiki kenkou shindan), which may bundle some cancer screenings in, but this varies a lot by employer.
How to Access Screenings Through Your Ward Office
This is the step most expats miss entirely. Every April, Japanese municipalities mail out cancer screening vouchers (がん検診受診券 / gan kenshin jushinkken) to eligible residents. The catch? They arrive in Japanese, so it’s easy to assume they’re junk mail and throw them out.
I’ve had this conversation more times than I can count — a friend or colleague mentions chest discomfort, I ask about their last screening, and they pull out a crumpled, unopened envelope from months ago. Those vouchers are genuinely valuable, so if you’re not sure what arrived in your post recently, it’s worth checking.
To use the municipal screening system:
1. Visit your local ward office (区役所 / kuyakusho) or city hall and ask about the がん検診 (gan kenshin) program
2. Register your interest and confirm which screenings you’re eligible for based on age and gender
3. Take your voucher to a participating clinic or hospital (a list will be provided)
4. Pay the subsidized co-payment at the time of your visit
Many wards — including Shinjuku, Minato, and Shibuya — now have multilingual support desks or English-language information available on their official websites. It’s worth calling ahead to confirm.
Private Clinics and Comprehensive Health Checkups (人間ドック)
If you want a more thorough, English-friendly experience, Japan’s 人間ドック (ningen dokku) system is exceptional. These are comprehensive health checkups offered by private hospitals and clinics that bundle multiple cancer screenings together with a full physical exam.
A standard ningen dokku typically costs between ¥30,000 and ¥60,000 out of pocket, though some insurance plans partially cover it. Higher-end packages at places like St. Luke’s International Hospital (聖路加国際病院) in Tsukiji or Tokyo Midtown Medical Center in Roppongi run closer to ¥80,000–¥100,000 but offer English-speaking staff, detailed reports in English, and a calmer, more private experience.
For many expats — especially those on company packages or with private health insurance from abroad — ningen dokku is the most practical route. You book it yourself, you get results explained to you in English, and everything happens in a single visit. The Japan Health and Research Institute (公益財団法人 日本健康・栄養食品協会) and the Ministry of Health, Labour and Welfare (厚生労働省) both publish guidelines on recommended checkup frequencies that reputable clinics follow.
What Foreigners Often Get Wrong
Assuming your company health check covers cancer screening. This is probably the most common mistake I see. The legally required annual checkup (teiki kenkou shindan) that employers must provide covers basic vitals, blood tests, and chest X-ray — but it does not automatically include colorectal cancer stool tests, mammograms, or endoscopies. Many expats leave their annual checkup thinking they’re covered, when in fact they haven’t had meaningful cancer screening at all.
The fix: ask your HR department explicitly which cancer screenings are included in your annual checkup, and fill the gaps either through your ward office or a private ningen dokku.
Skipping follow-up appointments. Japan’s screening system flags abnormalities (要精検 / you seiken — “further examination required”), but it doesn’t automatically schedule your next step. If you receive a result in Japanese you don’t understand, don’t ignore it. Take it to an English-speaking GP or use a medical interpreter service to get clarity before assuming everything is fine.
FAQ
Do I need Japanese language skills to get screened?
Not necessarily. Major hospitals in central Tokyo have English-speaking staff, and ward offices in foreigner-dense areas often have multilingual support. That said, bringing a Japanese-speaking friend or using a translation app for paperwork goes a long way at smaller local clinics.
Can I use my National Health Insurance card at a ningen dokku?
It depends. NHI covers standard medical consultations but ningen dokku is generally classified as a voluntary health checkup (自由診療 / jiyuu shinryo), meaning it’s not covered the same way as treatment. Some municipalities offer partial subsidies — check with your ward office.
What if I’m under 40? Is there anything available to me?
Municipal cancer screenings mostly begin at age 40 (cervical cancer screening starts at 20). If you’re younger and want screening, private clinics can run tests at your request — you’ll pay full price, but it’s absolutely possible.

You might want to read our guide to understanding health insurance options in Japan for expats, which covers both NHI and shakai hoken in detail and helps you figure out which system you’re enrolled in. Many readers also find our article on finding English-speaking doctors in Tokyo equally important — knowing where to go after a screening result is just as critical as getting screened in the first place.

Conclusion
Japan’s cancer screening infrastructure is genuinely world-class, and as a long-term resident, you have real access to it — often at very low cost. The system isn’t always easy to navigate if you’re not used to it, and I’ll be honest: the language barrier and the reliance on paper vouchers make it easy to fall behind. But once you know how it works, it’s straightforward.
My personal recommendation: start by checking what arrived in your mailbox from your ward office, and if you’re over 40, book a ningen dokku this year at an English-friendly clinic. Your future self will thank you.
Next step: Contact your local ward office this week to ask about your cancer screening eligibility, or browse English-language ningen dokku packages at hospitals like St. Luke’s International or Tokyo Midtown Medical Center to find one that fits your schedule and budget.
