There are several mountains called Mt. Tate ("tate" meaning "mansion" or "small castle") in Japan. The Mt. Tate referenced in the Houjou arc of Mirage of Blaze is located near the south-western tip of Chiba Prefecture. It was a part of Awa-no-kuni in the Sengoku Era and ruled by the Satomi Clan, who built Tateyama Castle there. Tateyama City grew out of the old castle town.
