A pure JavaScript port of the Kuromoji Japanese morphological analyzer that tokenizes Japanese text and returns part-of-speech information. It runs in both Node.js and the browser using bundled IPADIC dictionaries.

Use cases

• tokenize japanese text into words
• segment japanese sentences with no spaces
• get part-of-speech tags for japanese words
• build a japanese full-text search indexer
• analyze japanese text in the browser
• extract word base forms from japanese sentences

When to choose

• you need japanese word segmentation and POS tagging in JavaScript
• you want tokenization to run client-side in the browser
• you need basic-form extraction for search or text analysis

When to avoid

• you need languages other than Japanese
• you need state-of-the-art accuracy from neural tokenizers
• you need active development or official license clarity - the project is minimally maintained
