Gujō Hachiman Castle was built in 1559 by Endo Morikazu (遠藤盛数). Morikazu had barely finished the castle when he died, leaving it to his son Endo Yoshitaka. Yoshitaka later became a retainer to Oda Nobunaga and the direct control of the castle fell into the hands of Inaba Sadamichi, who renovated much of the castle. Yoshitaka returned to rule the castle following the Battle of Sekigahara. The castle was expanded following Tsunetomo's appointment to the castle in 1646. In 1870, during the Meiji Restoration, the castle was torn down during Japan's attempts to modernize.. Though the castle had been destroyed in the early Meiji Period, it was rebuilt in 1933. Unlike most reconstructed castles, Gujo Hachiman's was rebuilt with wood rather than concrete, but its interior does not follow its original design, nevertheless. The castle's hilltop location provides a beautiful view of the town in the valley below. Maple trees surround the castle and make the area particularly attractive during the autumn leaf season in early to mid- November. During this time, the colorful leaves are further showcased by a night time light display.
