Sunpu Castle is classified as a flatland castle, and is located in Shizuoka Prefecture. During the pre-modern age, it found itself within the borders of Suruga Province. It is associated with the Tokugawa clan. Dates in use: 1585 - 1869.

The castle that Tokugawa Ieyasu built here in 1585 replaced the fortified residence of its former lords & Ieyasu's former captors, the Imagawa. At Ieyasu's order, Daimyō from all over Japan contributed to its reconstruction in 1607. Just three short years later their efforts were reduced to ash whereupon Ieyasu once again ordered its reconstruction, this time with a massive seven-story main tower.
