A lexicon for Japanese tokenizer Sudachi.

Latest version

Python packages

Dictionary types

Sudachi has three types of dictionaries.

  • Small: includes only the vocabulary of UniDic
  • Core: includes basic vocabulary (default)
  • Full: includes miscellaneous proper nouns

Build from sources

SudachiDict needs Git LFS to download the sourses of the system dictionaries. If you fail to build the dictionaries, install Git LFS and git lfs pull.

Building the dictionaries fails with a locale other than UTF-8. Add -Dfile.encoding=UTF-8 to MAVEN_OPTS.
