JP Score answers one question: is this Steam 18+ game actually good?
Most uncensored adult games on Steam are made in Japan and were sold in Japan first — on DLsite and FANZA, where they gathered real ratings from the audience they were made for. Steam's review section, with its smaller sample and different audience, often buries genuine classics. We show both, side by side.
• What's included: 389 games — adult-only titles on Steam with sexual content, made by Japanese
developers/publishers or with Japanese language support.
• Matching rule: normalized exact title match only. If we can't confirm it's the same game, we say
"No Japanese rating data found" instead of guessing (43 matched so far).
• Score honesty: every rating shows its source (DLsite/FANZA) and review count, exactly as published.
Small samples are flagged ("based on only N reviews").
• π Acclaimed in Japan: 4.4+ / 5 with 100+ reviews.
• Today's pick: a daily rotation of games acclaimed in Japan but with under 500 Steam reviews.
• Buying: DLsite has an English storefront and sells worldwide. FANZA only sells to customers in Japan (we still show its ratings as evidence). Steam links are plain links, not ads.
Data sources: public Steam store data, the official FANZA (DMM) affiliate API, and DLsite's public product data. We never reproduce review text — only numerical data plus our own words.
This is an adults-only (18+) information site. Visitors under 18 are not permitted.
Links marked "Ad" are affiliate links (they never change the price you pay).
