History of the Okazaki Castle


 Tradition has it that the first Okazaki Castle was constructed at the present site in Sugo, Okazaki around 1455 by the Saigo family. In the first half of the 16th century, the Saigo family yielded possession of Okazaki Castle to Matsudaira Kiyoyasu, the 7th lord of the Matsudaira family (and the grandfather of Iyeyasu) that had risen into power in northern Mikawa.
 However, based on recent research, the prevailing belief is that the first Okazaki Castle was built at Myodaiji, Okazaki in the first half of the 15th century and that Matsudaira Kiyoyasu moved it to the present site in 1531. Incidentally, the original castle was most probably a fort the size of the current main citadel on a small plot of land.
  In 1590 however, Tanaka Yoshimasa - then lord of the castle - enlarged the precincts surrounded with moats and Lord Honda Yasunori built a complex castle tower well worthy of the name.  For 3 centuries Okazaki Castle has been honoured as the birthplace of the deified Iyeyasu and cradle of the Tokugawa Shogunate. It was guarded successively by the hereditary vassal daimyos who wielded enormous power. At the same time, Okazaki was valued as a strategic point along the Tokaido Road.  During the Meiji Restoration, the feudal clans were abolished and between 1873-1874, Okazaki Castle was demolished, leaving only its moat and stone wall. But in 1959 the three-tiered, five-floor donjon, together with the annex and wellhouse, were masterfully reconstructed according to the original model.

Our displays contain authentic historical materials to give our visitors an idea of what Okazaki and its feudal lords were like in the Edo Period.
