The Czech Republic and Japan formed a bond during the 2023 World Baseball Cup when the Czech national baseball team, mostly made up of amateur players, played against Japan and lost 2-10. The Czech pitcher Ondrej Satoria struck out Shohei Ohtani, earning admiration from Japanese fans. In a related development, Japanese developer Eba Game is launching a game called Ball Boy Simulator on Steam, which includes Czech language support due to a request from a Czech user. The game explores the psychological horror of high school baseball clubs and incorporates AI-generated content for various elements. The quality of localization for the Czech audience is yet to be determined.
