History
Yanagawa was under the control of the Date Clan from 1189, when Date Tomomune received the land, until Date Masamune forfeited it to Toyotomi Hideyoshi in 1590. In 1598, the entire Fukushima Basin (Shintatsu Plain) became the territory of Uesugi Kagekatsu and Suda Nagayoshi became the lord of Yanagawa Castle.[1]
By 1960, the town of Yanagawa had merged with the villages of Awano, Sekimoto, Shirane, Ooeda, Isazawa, Tomino, and Yamafunyuu. The town's symbol was established in 1965, and in 1983, cherry blossoms, persimmon trees, and wagtails were designated as the town's official flower, tree, and bird, respectively.[2]
A whole body skeleton of Paleoparadoxia was excavated in Yanagawa on August 21, 1984. The skeleton is named the “Yanagawa Specimen”.[1]
In 2006, Yanagawa merged with the towns of Date, Hobara, Ryōzen and Tsukidate, creating Date City.
Yanagawa Castle was constructed in the Kamakura Period and used as the headquarters of the Date Clan from the time of the 11th lord of the Date Clan, Date Mochimune, through to that of the 14th lord, Date Tanemune. Mochimune's son, the 12th lord, Date Shigemune was influenced by Higashiyama Culture and built the inner garden, including Shinji Pond, which is still visible at the site today. The 17th lord of the Date Clan, Date Masamune stayed at Yanagawa Castle when the last member of the Date Clan to own the castle, Date Tessai Nyuudou resided there.[1]
