Daikokudo

There was a schoolhouse in the commentary version. It seems that he initially kept the treasures of the Shrines, but when he was a forty-second ninja, he began to devour Daikokuten. The structure of the wall is an interesting bellows type.

It's like a schoolchild like Odakyodo who feels like a part of Shosoin. Originally it was a place that housed treasure of the mountain in the warehouse, but it is said that the Shinzo superstar relocated Daikokuten from others and settled here Then it became the origin of Ashikaga Shichi Fukami and became faithful.
