Kashii Shinto Shrine has been called "Kashii-byo" since ancient times. Chuai, the 14th Emperor, built his temporary palace, Kashii-miya of Chikushi, here( Kogû Shrine). The origin of the modern name of Kashii can be traced to this.

In the 4th century, the Emperor Chuai came down to Chikushi to conquer the rebellious Kumaso tribe of Kumamoto. Unfortunately, he died before he accomplished his intension, and his plan was taken over by the Empress Jingu, who, according to the legend, disguised herself in men's clothes at Mishima and conquered all of Kyushu. Afterwards, she invaded the southern part of the Korean Peninsula. And legend has it that there was a continuous flow of tributes and cultural assets from overseas. It is said that in order to pay homage to this achievement this shrine has been exclusively designated "byo", instead of "sanryo"(imperial tomb) or "jingu".

The shrine has a deep connection with the emperors from generation to generation. Before the Meiji Restration there was a traditional event of sending annually the sacred water of longevity to the imperial palace in Kyoto, and in every ten years the emperor sent an imperial envoy to the shrine with votive offerings in return.

The main shrine is built in Kashii style which is unique design. Please take this opportunity to pray in this unique building and visit the other interesting cultural assets in the area.
