ATOK 辞書ユーティリティ

ATOK Dictionary Utility (辞書ユーティリティ) is a dictionary and input management tool for ATOK, Japan's most widely used Japanese input method editor (IME) for macOS and Windows. It allows users to add, edit, and manage custom dictionaries, user-defined words, and input settings to personalise the IME's conversion and suggestion behaviour. The utility is used by writers, translators, programmers, and anyone regularly typing Japanese on macOS who needs fine-grained control over vocabulary and input preferences. It is distributed as a companion utility to ATOK itself, which handles the actual Japanese text input.
