Sakazakiko Castle (Mikawa)


Sakazakikojou (1).jpg


Sakazakikojō was built by Hiraiwa Shigemasu around 1522. Although this site is called 'Old Sakazaki Castle' in relation to Sakazakijō, it's not clear to me which fort existed first, and both seemed to have existed simulataneously. 'Old Castle' belonged to the Hiraiwa Clan, and 'New Castle' belonged to the Amano Clan, but these two clans were related and fought alongside each other. I suppose the names may have been bequethed to the castle ruins anachronistically. Or Sakazakikojō was abandoned before Sakazakijō.

Castellan Hiraiwa Chikayoshi, born at Sakazakikojō in 1542, served Tokugawa Ieyasu alongside Amano Yasukage in the middle 16th century. Chikayoshi tutored Matsudaira Nobuyasu, Tokugawa Ieyasu's first son, until Nobuyasu was suicide(-execute)d on the orders of Oda Nobunaga in 1579. It is said that Chikayoshi offered his own head in place of Nobuyasu's, but was confined to his estate / put under house arrest (at Sakazakikojō?) until after the execution. Hiraiwa Chikayoshi helped plan the construction of Kōfu Castle in 1583. Sakazakikojō was likely inhabited no later than 1590.

Visit Notes

Sakazakijō is fortification site which is now that of the village of Sakazaki in Kōta Township, Nukata County. The specific locality (koaza) is called 'Shiro (castle)' and this area is slighty elevated and forms a squarish footprint. There are earthworks remaining in the form of dorui (earthen ramparts), and karabori (dry moats) identified by castle-explorers, but I think the ruins are on private property. There is also a waterway said to be the inheritor of a mizubori (wet moat).
