This museum, in front of Sumpu Castle Higashi Gomon Tatsumi Yagura (the southeast turret), was opened in January 2023 to promote the history and charm of Shizuoka. In the free area on the first floor, there is an in situ display of the remains of a road and stone walls from the late Sengoku (Warring States) Period, which were unearthed from this site. In the exhibit rooms on the second floor, you can find an introduction to the life of Tokugawa Ieyasu (the first shogun of the Tokugawa Shogunate) and the history of the Imagawa Clan (who laid the foundations of Shizuoka). From the observation lounge on the third floor, you can enjoy the view of Sumpu Castle Park.
