Because a Tendai Sect monk was invited to serve as head priest and the fact that the temple precinct was previously the site of a temple named Renge-ji Temple, the newly rebuilt temple was given this name and devoted to the Tendai Sect.
開山として招かれたのが天台宗僧であること、境内地が蓮華寺という寺院の跡地であったことから、寺号が改められ、天台宗に帰属するようになった。
