Saitō clan
Saitō Toshifuji (斎藤 利藤) first built Nagara Tenjin Shrine during the Kanshō era (1460–1466) with the purpose of making it the family temple for the Saitō clan. Saitō Toshiyasu (斎藤 利安) completed repair work during the Eishō era (1504–1520), but Ikeda Terumasa was responsible for major upgrades in 1588.
