History
According to the Chinzei Yoryaku (鎮西要略), in 724, Mibu Harunari, then governor of Hizen Province, received an oracle from the Hachiman deity to built a shrine on the land where a thousand chestnuts were growing. It became a dependency of the Usa Hachiman-gū in the Johei era (931-938). According to records of the Dazaifu, in 999 oil gushed out of the ground at the shrine and was presented to the Imperial Court. It has been recognized as the ichinomiya of Hizen Province since the Heian period, however, the title is disputed by the Yodohime Shrine, located in the city of Saga. The Chiriku Hachiman-gū burned down in December 1228. It is an indication of the importance of the shrine that the Court dispatched Konoe Kanetsune and Tsuchimikado Sadamichi, two high-ranking nobles in 1230 to investigate and discuss the reconstruction. During the Sengoku period, the shrine was the site of numerous battles and was destroyed several times, most notable in 1534 when it was razed by the Ōuchi clan; it was not rebuilt until 1583 under the sponsorship of the Ryūzōji clan. It continued to be supported by the Nabeshima clan, the daimyō of Saga Domain during the Edo Period. In 1609, it was awarded a plaque by Emperor Go-Yōzei recognizing its position as ichinomiya of Hizen Province.

During the Meiji period era of State Shinto, the shrine was designated as a National shrine, 3rd rank (国幣中社) under the Modern system of ranked Shinto Shrines

Okayu Matsuri-
The main festival of the shrine held on March 15th is affectionately called Okayu-san (粥祭) by the locals, and involves a type of fortune-telling that uses rice porridge to predict whether the harvest will be good or bad that year. On February 16, porridge is boiled with water from the Hara River in front of the shrine, divided into four pots representing the four provinces of Chikuzen, Chikugo, Hizen, and HIgo and placed in the shrine. It is taken out on March 15, and the direction where mold is growing is the region that will have a good harvest that year.
