Uesugi Kenshin built the Otate in present-day Niigata Prefecture as residence for Uesugi Norimasa, Kantou Kanrei, when the latter escaped from Hira Castle in 1552, which was under attack by Houjou Ujiyasu with 20,000 soldiers, and sought aid from Kenshin (Nagao Kagetora at the time) at Kasugayama Castle. Kenshin later used the Otate as his public government office.
In 1578, after Kenshin's death, Kagetora escaped from Kasugayama Castle and set up his headquarters at Otate on June 18th during the Otate no Ran. Kagekatsu attacked Otate in February of the following year, finally destroying it by flame in April after Kagetora and his family had evacuated.
Nothing of the building (which had not been grandiose in the first place) remains today; the area is now mostly devoted to housing districts with a small "Otate Park."
