Later in 902, Emperor Daigo made the temple as a temple for prayer for 'the Imperial Court with comfort, home land protection, and long lives of descendants,' so it was given a title of 'Chogosonshi-ji Temple' from the Emperor ('Cho' is for the Imperial Court, 'go' is for protection, 'sonshi' is for descendants) by the Imperial Court.
その後、902年（延喜2年）に醍醐天皇が、「朝廟安穏・守護国土・子孫長久」の祈願寺としたことから、「朝護孫子寺」の勅号を賜った。
