Most design systems are born English-first and struggle with Japanese: line-height assumptions break, form patterns differ, and business software in Japan has its own conventions around density and information hierarchy.
This system was built Japanese-first: a type scale tuned for CJK glyphs, form patterns that respect Japanese business data (names, addresses, furigana), and documentation written for the engineers who actually consume it.
