Raison 賴尊 / 頼尊 (Heian or Kamakura period; lifedates unknown) — Japanese Esoteric (Shingon-tradition) scholar known principally as the author of the Jīngāngdǐng jīng jì-shì 金剛頂經偈釋 (KR6j0028, T61n2224) — a verse-commentary (jì-shì = explanation of the gāthās) on the Vajraśekhara-sūtra (KR6j0024, T18n0865). The work is a doctrinal exegesis of the verse-passages of the Vajraśekhara — one of the principal Esoteric scriptures — with characteristic Shingon-school doctrinal interpretation.
His other works are not preserved in the Buddhist canon. The DILA biographical information records only his Japanese provenance and his authorship of the Jìshì; no further dates or biographical data survive.
