An imperial mausoleum at Utano Baba-cho, Ukyo-ku, Kyoto, managed by the Imperial Household Agency as the tomb of Emperor Koko, the 58th emperor. According to a Kyoto City trial excavation report, the plot just south of the mausoleum once held a temple called Kowa-an, and a 2015 survey there found a Muromachi-period surface.
