Tachibana studied literature under Shuan Kagawa in Kyoto.
Tachibana made extensive tours curing the sick and making literary discourses and in the Sanyo district he was looked upon as a second Kobo-Daishi, a distinguished priest of yore. Toward the end of the Temmei Era he was appointed physician to the Court. Nankei wrote many books and his Tozai-yuki, an account of his travels, is still being read.
