The national framework is the same wherever you are — nationwide insurance, the free hokenjo testing network in every prefecture, and the AIDS Core Hospital system for HIV care. What changes outside Tokyo is density: the self-pay PrEP/PEP clinics and the gay-community organisations cluster in a handful of big cities and thin out sharply beyond them. Here are the major hubs and the rural fallback.
🌆 The Major Hubs
Japan's gay-community HIV infrastructure grew up around community centres in a few cities. These are your best regional contact points for testing events, PrEP referrals, and peer support.
| City | Community / services | Notes |
|---|---|---|
| Osaka | MASH Osaka and the community centre dista (Kansai) | The strongest hub outside Tokyo. Runs community HIV/STI testing, including low-cost weekend testing at partner clinics. |
| Nagoya | Gay-community centre (Chūbu, est. 2004) | HIV prevention and testing outreach; regional contact point. |
| Fukuoka | Gay-community centre (Kyūshū, est. 2006) | Serves western Japan; testing and prevention outreach. |
| Sendai | Community outreach (Tōhoku) | Northern Japan contact point. |
| Naha (Okinawa) | Community outreach | Southern-islands contact point. |
Near one of these cities? The community centre is usually a faster, friendlier way into testing and PrEP referral than cold-calling clinics. They know which local providers are gay-friendly and which run current testing events.
🩸 Testing Anywhere in Japan
Wherever you are, your prefecture runs free, anonymous HIV and syphilis testing at the local hokenjo — this genuinely covers the whole country, not just the cities. Search your prefecture or city name plus 保健所 エイズ検査 (hokenjo AIDS testing), or ask the nearest big-city community centre. The hokenjo guide below covers what that testing does and doesn't include.
Postal home testing is the great equaliser for rural areas — a mail-in kit reaches anywhere with an address.
🏥 Rural and Smaller Cities
Away from the hubs, expect this:
- HIV care: still there — every region has designated AIDS Core Hospitals. You may travel further to reach one, but the specialist network is genuinely national.
- PEP: harder. A dedicated self-pay PEP clinic may not be close. Your fallback is a hospital emergency department for a bridging supply, then travel to the nearest specialist centre. Don't let distance push you past 72 hours — act locally first.
- PrEP: limited nearby. Many men in smaller cities rely on periodic trips to a city clinic plus personal importation of generics, with monitoring bloods done locally.
In rural areas, don't assume a local general clinic knows PrEP, doxyPEP, or gay men's sexual health. Bring the specific terms from the vocabulary guide below and be ready to travel to a city hub for anything the local clinic can't do.
