Okazaki Castle is classified as a hilltop castle (its layout: Teikakushiki), and is located in Aichi Prefecture. During the pre-modern age, it found itself within the borders of Mikawa Province. It is associated with the Honda, Mizuno clans. Dates in use: 1531 - 1873.

Yes, it is a concrete reconstruction but it is a site of some significance as it was the birthplace of one of Japan's most well-known historical figures, Matsudaira Takechiyo, better known to the world as Tokugawa Ieyasu.

Remaining today are sections of stonework & moat. As at early 2010, a turret had been rebuilt. And, as described to me by David LaSpina (who I thank for use of these photos) the turret sits in the middle of the car park.
