If you're building Japanese web interfaces with AI coding agents, this is the missing piece. It extends Google's DESIGN.md format with the typography rules that actually matter for CJK: proper font stacks that cascade from Noto/Hiragino through system fonts, line-height specs in the 1.7-2.0 range instead of Western defaults, letter-spacing values, kinsoku shori line-break enforcement, and OpenType feature flags for proportional punctuation. Includes 24 real-world reference files from MUJI, Mercari, SmartHR, note, and others. Drop one in your repo root next to AGENTS.md and your agent will stop generating Japanese UI with 1.4 line-height and missing mixed-typesetting rules. Solves a specific problem cleanly.
