An App Store listing in Japan needs Japanese keywords, and not a machine translation of English ones: people there search differently, in a script where word boundaries do not exist the way they do in English.
AI keyword suggestions now return terms in the language of the storefront you are working on, transcreated rather than translated. The work behind it was mostly a model change: transcreating English intent into Japanese, Korean or Chinese search behaviour turns out to be a task smaller models quietly fail at while producing confident English output.
If you run listings in several markets, this is the release that makes multi-market tracking worth using end to end.
