About

502 games on Steam, matched by exact title, 53 found in Japan

Most 18+ games on Steam came out in Japan first, where a lot more people rated them. We put the two scores side by side.

Two store pages with the same title, matched

What we do

Match a Steam game to its Japanese store page only when the titles are the same, letter for letter.

A question mark crossed out

What we never do

Guess. If we cannot confirm it is the same game, the page says "No Japanese rating data found".

What the 🏆 badge means

Badge rule: score 4.4 or higher and 100 or more people
Both bars have to reach the gold part: 4.4 or higher, rated by 100 people or more. Right now 24 games do.

Where you can buy

A globe

DLsite

Has an English store and sells worldwide.
