IBM Plex extended to Japanese, delivering a unified design system across one of the most complex script combinations in global typography.
About
IBM Plex Sans JP is a substantial undertaking that brings the Plex family's consistent design language to Japanese, covering thousands of kanji alongside hiragana and katakana. The result is a coherent typographic system for Japanese–Latin bilingual interfaces, publications, and software products that need reliable cross-script harmony. Its seven weights give designers meaningful control over typographic hierarchy in both Japanese and Latin text settings.
Classification
IBM Plex Sans JP extends the Plex design philosophy into Japanese, harmonising kanji, hiragana, and katakana with Latin and Cyrillic counterparts through unified weight progression and proportional logic. It reflects a genuinely integrated approach to multi-script typography rather than a superficial adaptation.
