ATOK 2017
ATOK 2017 is a Japanese input method editor (IME) for macOS, developed by JustSystems. It enables users to input Japanese text using various input systems including romaji, kana, and stylus input, with support for kanji conversion, user dictionary customization, and predictive input. ATOK is widely used in Japan by business professionals, writers, and anyone regularly typing Japanese on Mac, and is available in both consumer and enterprise (J-License) versions. The app integrates deeply into the operating system's input method layer.

1 suggestionJustSystems has confirmed that ATOK 2017 for Mac runs under Rosetta 2 and is receiving ongoing updates and support via their J-License program. However, there is no publicly confirmed native Apple Silicon (Universal Binary) version of ATOK 2017 available yet. Given that Apple will remove Rosetta 2 in macOS 28 (September 2028), you should contact JustSystems directly to confirm whether a native Apple Silicon build is planned for ATOK 2017, or whether you will need to migrate to a newer version of ATOK (such as ATOK 2023 or later if available) before the September 2028 deadline. Check the JustSystems macOS support page regularly for announcements. As a contingency, be aware that Apple's built-in Japanese input methods (Hiragana, Katakana) and third-party options like Google Japanese Input (which has confirmed native Apple Silicon support) can serve as alternatives if ATOK 2017 does not receive a native update in time.
