Kuromoji is a self-contained, easy-to-use Japanese morphological analyzer written in Java, supporting word segmentation, part-of-speech tagging, lemmatization, and reading extraction. It ships with multiple dictionaries (IPADIC, UniDic, etc.) and is designed with search applications in mind.

Use cases

• segment japanese text into words
• tag japanese text with part of speech
• lemmatize japanese verbs and adjectives
• extract furigana readings for kanji
• tokenize japanese text for full-text search
• analyze japanese sentences in a java application

When to choose

• you need japanese tokenization in a JVM project like Elasticsearch or Lucene
• you want a self-contained analyzer with no external dependencies
• you need multiple dictionary options including NEologd variants

When to avoid

• you need a non-JVM language like Python or Ruby
• you need modern neural NLP models rather than dictionary-based analysis
• you need actively developed features, as the project is in maintenance mode
