【Designated by the City：Historic Site】Nisumi Utaki Sacred Site

Located at the hilltop about 1km northwest of the Masubari settlement, the Utaki is strongly fortified with a sheer cliff to the north, facing the ocean, and leading to the Shirakawa-Hama to the west. There are two water wells nearby, the Sagai-I, at the bottom of the cliff, and another, the Kanagi-i, towards the ocean. There are remains of a stone wall around the Utaki that appears to be a castle wall, but the scale of the whole thing is unclear.
However, from a wide area in the surroundings, including the farm fields, there have been findings of celadon and Southeast Asian pottery pieces, and taking into consideration of the location of the wells and other factors, it suggests that the area was once home to a settlement. According to the local historian, Kenpu Inamura, the Nisume Utaki was the fortress of the chieftain, Nisume-aji, but because the location was too small, the chieftain later moved to where the Tobitori Utaki sacred site is.
