Before you install
- Requires SudachiPy to be installed and functional; dictionary file is downloaded during installation, requiring network access and disk space.
- High install friction: the package downloads a large dictionary file (sudachidict_full-20260723.tar.gz) during setup.
- Active maintenance with recent releases; last commit 2026-07-24.

What it is and what it does
SudachiDict-full is a dictionary resource package for Japanese natural language processing, specifically designed to work with SudachiPy. It is one of three dictionary editions (small, core, full) and provides the most comprehensive morphological lexicon for tokenizing and analyzing Japanese text. The package manages dictionary resources as a Python package, automatically downloading the dictionary data during installation rather than bundling it directly.
The full edition is the largest and most complete option, suitable for applications requiring broad vocabulary coverage. It integrates with SudachiPy v0.5.2 and later, where you can specify the dictionary directly from the command line or program. Installation involves downloading a large archive, so it has high install friction but provides the most extensive Japanese morphological analysis capabilities.
Use it for
- Building Japanese text search or indexing systems that require accurate morphological analysis
- Processing Japanese documents for NLP tasks like named entity recognition or dependency parsing
- Running production Japanese language processing pipelines where vocabulary breadth matters
- Developing Japanese chatbots or conversational AI that needs comprehensive tokenization
