Minamoto no Yoritomo
During the late Heian period (1062) Minamoto no Yoriyoshi and his son, Minamoto no Yoshiie donated thousands of zelkova saplings to the shrine as part of a prayer for victory in military campaigns in Mutsu Province, and in 1182 Minamoto no Yoritomo made an invocation for the safe delivery of a child during the pregnancy of Hojo Masako. Following the start of the Kamakura period, Minamoto no Yoritomo extensively rebuilt the shrine. It was rebuilt again in 1590 under Tokugawa Ieyasu and after a fire in 1649.
