At Nishina Shinmeigu, the city records, the shrine has been rebuilt every 20 years. The 27 ridgepole tablets from the 2nd year of Eiwa (1376) to the 3rd year of Ansei (1856) are regarded as a detailed source on the rebuildings, the Nishina family line, its retainers, and the circumstances of construction, and are an Important Cultural Property. The main hall and middle gate are National Treasures.

A saddle room, a stable, an earth-floored kitchen, a hemp-scutching room and a mezzanine all fit in one building. It is an Important Cultural Property, which the city calls valuable for understanding farm-village living.

The city records that the framework of Omachi's town center was laid between the Kamakura and Muromachi periods by the Nishina clan's town planning. Behind the townhouses ran water drawn from the Kashima River; in front flowed the "Machigawa." Nyakuichioji Shrine was enshrined at the key point where that water was divided, at the northern edge of the town.
