Echizen Katsuyama Castle (Echizen Katsuyama-jo) was built in 1579 by the daimyo Shibata Katsuyasu. It changed hands frequently due to war. As Japan entered the era when the entire country was ruled by the Tokugawa family, the daimyo Ogasawara Nobutoki raised the castle on the pretext of restoring an old castle. Due to fires, it was never completed. The existing five-tiered, six-storied castle tower was built in a different place in 1992. For the stone wall, 6,500 large rocks were used.
