Site of Mt.Tenzin Castle
Mt. Tenzin (height 250mt) is the site of a mountain castle that occupied a large territory. The keeper of the castle was called Oguni. It is not clear when the castle was constructed, but the existence of someone called Oguni has been confirmed in the area in the Muromachi period (approximately 1336 to 1573). In the 11th year of the Tensho era (1583) Kurasuke Shimizu became the keeper of this castle. The castle then came under the control of the Uesugi family, and in the 3rd year of the Keisho era (1598) control of the area passed to Aizu (in present day Fukushima Prefecture) under Kagekatsu Uesugi and the castle ceased to be used.
In the NHK historical drama based on the book by Masashi Hisaka, Tenchijin, the younger brother of the main character Naoe was portrayed as the keeper of the Mt. Tenzin Castle, and both brothers devoted their lives to serving the Uesugi family.
