Junkei 順繼 — Late-Kamakura or Nanbokuchō-period Japanese Shingon scholar-monk, the author of the Shaku makaen-ron dai-jū kō tanzaku 釋摩訶衍論第十廣短册 (KR6t0243, T79n2537), a short scholastic text on the tenth chapter of the apocryphal Mohe-yan-lun 釋摩訶衍論 (the Treatise on the Mahāyāna Commentary, a pseudo-Nāgārjuna work attributed to Vajrabodhi-Vajrasattva).
The work treats the kanjō-retsu-kōshō-futai-mon 勸劣向勝不退門 (“Gate of Encouraging the Inferior toward the Superior, Non-Retrogression”) and the four-faith principle-contemplation (四信理觀), framed as a scholastic question-and-answer document. The text indicates a scholastic-tradition setting (referencing 學者 — “scholars” — and the standard medieval-Shingon-Tendai Shaku makaen-ron commentary tradition).
No lifedates are recorded in DILA; the work itself has no internal date but is conventionally placed in the late Kamakura / Nanbokuchō period.
