ATOK (エイトック /ˈetoku/ or /ˈeɪtɔːk/) is a Japanese input method editor (IME) produced by JustSystems, a Japanese software company.
Contents

ATOK is an IME with roots from 1983 and DOS, but it now supports a large number of platforms including Linux, macOS, Windows, Android, and iOS.

Sun Microsystems chose ATOK as their input method when running under the JP locale in Solaris 10 and above, enhancing Sun's already strong Japanese language support. For embedded systems, JustSystems has developed +ATOK. Some Japanese mobile phones, PDAs, video game consoles (PSP, PS3 and Wii), digital video recorders, automotive navigation systems come with +ATOK.

Once ATOK meant Automatic Transfer Of Kana-kanji. Now, it means Advanced Technology Of Kana-kanji Transfer. It is occasionally taken to stand for Awa-TOKushima, site of the headquarters of JustSystems, or ASCII TO Kanji.
