Nagaoka Temmangu is a Shinto shrine located in Nagaoka City to the south of Kyoto. It is a shrine dedicated to Sugawara no Michizane who was a scholar, poet, and politician of the Heian Period. Nagaoka Temmangu was built in 901 when Michizane was demoted to a minor official of Dazaifu, in Chikuzen Province. Nagaoka was a place where Michizane visited frequently accompanying with Ariwara no Narihira , his contemporary poet, and spent his time to compose poems. In 1638, Prince Hachijo Toshihito constructed a pond named Hachijo-ike and donated it to the shrine.
