An HIV diagnosis here drops you into one of the best-performing treatment systems anywhere — over 99% of people in care reach an undetectable viral load. Care is specialised and concentrated in a designated hospital network, and while the medication looks expensive on paper, a specific disability-certificate route brings your real cost right down. This is the pathway from diagnosis to stable treatment, and the support around it. For the biology, treatment, and what U=U means, use the general HIV guides linked at the foot of this page.

🏥 Who Treats You: The AIDS Core Hospital Network

HIV care runs through a national network of AIDS Core Hospitals (エイズ治療拠点病院) — designated hospitals with physicians specifically screened and approved to manage HIV. After a confirmed positive result, you're referred into this network, not left with a general clinic. Every region has core hospitals, so care is available nationwide even if you have to travel further to reach one.

In Tokyo, the AIDS Clinical Center (ACC) at the national medical centre is the flagship.

💴 The Cost, and How It Drops

On paper, antiretroviral therapy (ART) is expensive. In practice, two things make it manageable:

  1. Health insurance takes you to the standard 30% payment — roughly ¥45,000–60,000 a month for combination ART before further help.
  2. The disability certificate (身体障害者手帳 for immune-function disability) unlocks the 自立支援医療 / 更生医療 subsidy, which cuts your monthly out-of-pocket cost sharply — often to somewhere between ¥0 and ¥20,000 a month, scaled to income.

Apply for the disability certificate early. Your HIV social worker or core-hospital team will help you file it. Two catches: eligibility uses clinical thresholds (CD4 count, viral load, AIDS-defining history), so not everyone qualifies straight away, and processing usually takes around two months. Ask about the High-Cost Medical Expense cap to limit what you pay in the meantime.

⚖️ The Legal Position and U=U

  • There is no HIV-specific criminal law in Japan, and no reported HIV-criminalisation prosecution to date. Not disclosing your status to a partner is not covered by any specific criminal statute here.
  • U=U — an undetectable viral load means HIV can't be transmitted sexually — is established science and applies to you here like everywhere. With no HIV-specific disclosure law, U=U is a question for your relationships and your honesty, not a courtroom. The U=U guide below explains what "undetectable" means and the timeline to get there.

Stigma, not the law, is the harder reality here. Disclosure rates are low and many people living with HIV keep their status very private out of fear of discrimination. That's a valid, self-protective choice — and it's exactly why the peer support below matters.

🤝 Peer and Social Support

You don't have to do this alone. Core hospitals have medical social workers (医療ソーシャルワーカー) attached to HIV care to help with the certificate, the costs, and disclosure decisions.

  • PLACE Tokyo (ぷれいす東京) — counselling, peer support, and practical help for people living with HIV; long-established and trusted.
  • CHARM (Osaka) — multilingual support, especially strong for non-Japanese speakers and migrants living with HIV.
  • akta and the regional community centres — community connection and referral.

The Mental Health guide below lists affirming, English-capable support for the emotional side of a new diagnosis.
