All of Stata's interface—all menus and all dialogs—is now available in Japanese.
If your computer language is set to Japanese (ja), Stata will automatically use its Japanese setting. To change languages manually using Windows or Unix, select Edit > Preferences > User-interface language... using Mac, select Stata > Preferences > User-interface language... You can also change the language using the set locale_ui command.
StataCorp gratefully acknowledges the efforts of LightStone Corporation, Stata's official distributor in Japan, for the translation to Japanese.
