Tochio Castle
History. The exact date of the castle's foundation is unknown but built in the Muromachi period. In 1543, Uesugi Kenshin left Kasugayama Castle and entered the castle as a joint commander by Nagao Harukage`s order. In 1544, Kenshin made his first battle against local lords opposed to the Nagao clan in the castle and broke the siege. In 1548, Kenshin returned to Kasugayama Castle as a feudal load of the Nagao clan. The castle is now only ruins, with some earthenwalls, well and moats. Its ruins have been protected as a Prefectural Historic Site. Tochio Castle History
