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.

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.
