Typed Japanese is a TypeScript type-level library that encodes Japanese grammar rules as a DSL, letting users write and verify grammatically correct Japanese sentences via the TypeScript compiler. It also powers an interactive course and playground that teach Japanese grammar through type-checked code examples.

Use cases

• learn japanese grammar with typescript
• verify japanese sentence grammar using the type checker
• model japanese verb conjugations as types
• build a dsl for japanese sentence structure
• use type-level programming to validate natural language
• let llms output grammar analysis that can be type-checked

When to choose

• you already know TypeScript and want to learn Japanese grammar hands-on
• you want compiler-verified construction of Japanese sentences
• you need a structured, verifiable intermediate format for Japanese grammar analysis
• you want an interactive, beginner-friendly grammar course with type-checked examples

When to avoid

• you need production NLP parsing of arbitrary Japanese text
• you want a general-purpose Japanese translation or dictionary tool
• you don't use TypeScript and won't adopt its type system
• you need full coverage of Japanese grammar beyond the supported subset
