Wakasa Kokubunji Temple is thought to have been founded upon the order of Emperor Shomu to build Kokubunji Temples in various provinces for the purpose of protecting nation with Buddhism. There used to stand an old Kokubunji Temple at the site of the present one whose length of one side was two Cho (about 218 meters), a part of which is now remade into a park with historic sites. In the temple precincts is a big ancient burial mound on which Wakasahime Shrine is enshrined. This kind of architectural combination of a temple and a shrine built on an ancient tumulus is rarely found across the nation.
In the precincts of Kokubunji Temple that we see now, Shakado-hall standing at the site of Kondo, the main hall, enshrines a great statue of Shaka Nyorai which is said to be the biggest one among the statues of Shaka Nyorai in Wakasa region. Besides this, Yakushido Hall enshrines a wooden seated statue of Yakushi Nyorai designated as an important cultural property. This statue has been the object of faith among the devout local people.
