Tsu Castle is classified as a flatland castle (its layout: Rinkakushiki), and is located in Mie Prefecture. During the pre-modern age, it found itself within the borders of Ise Province. It is associated with the Tomita, Tōdō clans. Dates in use: 1571 - 1871.

When the three-story turret was rebuilt in 1958, certain features were introduced to make it more visually appealing. Instead of the very vanilla-looking turrets seen in photos from the dawn of the Meji period, the rebuilt turret sports six additional gables, four on the lowest layer & two on the middle layer. Finally, it is topped off by a pair of fire-fighting Shachi.

Remaining today, there are reasonable sections on stonework & about three-quarters of the inner moat.There is also a relocated gate. The striking, red gate is of the top-heavy, Yakui style.
