En un regard
Le château en bref
Ogawa Castle (小川城), also known as Ogawa-Shimo-jō, was located in Ogawa-chō Shimo, in the city of Anjō (Aichi Prefecture). This fortification on the edge of a plateau is said to have been founded around 1446 by Ishikawa Masayasu, a former supporter of Ashikaga Mochiuji who had settled in Mikawa. The Ishikawa maintained close ties with the Honganji school of Buddhism and the temple Honshōji, and later submitted to the Matsudaira of Anshō; their lineage would go on to produce Ishikawa Kazumasa, a close associate of Tokugawa Ieyasu. No siege and no date of abandonment are documented. A stone monument stands in Honjō Park, but no surviving enclosure is clearly identifiable; aerial photographs from the 1940s–1950s suggest a former quadrangular layout east of the park, without archaeological confirmation. The exact location remains debated, and no heritage protection is known.
