Hisaizu Shrine is located in Iwatsuki-ku, Saitama City, Saitama Prefecture. The enshrined deity is Okuninushi no Mikoto. It is said that the shrine was founded by the Haji clan from Izumo during the reign of Emperor Kinmei (539-571). Later in 1457, when the Ota clan built Iwatsuki Castle under the order of Uesugi Sadamasa, the shrine was designated as the guardian of Iwatsuki Castle.
The present main hall was built in 1789. The most distinctive is the Third Torii Gate, which is built of Japanese cypress plain wood. The wood, which had been used for Itagaki Minami Gomon (the south gate) of Naigu (inner shrine) in Ise Shrine, was dismantled at Shikinen Sengu (reconstruction of all the buildings of Ise Shrine done once in every 20 years) and reconstructed into the Third Torii Gate in 1993. The shrine forest is designated as “Furusato no Mori (Hometown Forest)” by the prefecture.
