It is said that Tokugawa Ieyasu stopped by Tokuei-ji Temple during his escape from Sakai, where he was staying, to his home base in Okazaki of Mikawa Province, when the Honno-ji Temple Incident occurred in 1582. In later years, Ieyasu donated forests, rice fields, and farmland surrounding the temple as a token of his gratitude. The main hall of the temple is decorated with tiles of the hollyhock crest of the Tokugawa family, which the Tokugawa family permitted for use.
