Kakuōzan Nittai-ji is a Buddhist temple located in the city of Nagoya, Aichi prefecture, Japan. It was built in 1904 in order to keep the ashes of Buddha, given to Japan by the Kingdom of Thailand. ”覚王” literally means "Enlightenment King," referring to the Buddha, and “日泰” means Japan and the Kingdom of Thailand in Japanese.
Usually, each temple in Japan belongs to a religious sect. However, Nittai-ji doesn't belong to any religious sect. Every three years, 19 religious sects take their turn to dispatch a chief priest to Nittai-ji. Usually, the ambassador of the Kingdom of Thailand visits Nittai-ji on his birthday.
