Settle

A job board for foreigners in Japan that states visa and Japanese-level facts up front

Japanese job ads rarely say whether the employer sponsors a visa, how much Japanese you really need, or whether foreign staff are welcome. Settle has an LLM read every listing and label those three things with quoted evidence. Listings stay in the original Japanese; the UI and labels are in English, Chinese and Vietnamese. Around 2,500 Tokyo listings are ingested continuously and served as a fast static site.
