Akizuki-jou, or Akizuki Castle, was once located in Akizuki-cho, Asakura, Fukuoka Prefecture.
The origin of the castle dates back to 1203 when Harada Tanekatsu built a mountain castle in Mt. Koshouzan (856m above sea level) and his residential castle at the foot of the mountain. He changed his name to Akizuki Tanezane and the residential castle was occupied by generations of the Akizuki family.
In 1587, faced by Toyotomi Hideyoshi’s massive army surrounding the mountain castle, Akizuki Tanezane surrendered to Hideyoshi and the mountain castle was abandoned.
In 1924, Kuroda Nagaoki, who was granted the land of Akizuki, transferred the residential castle to the old mountain castle and made extensive renovations. The ruins we see today are from this castle, in which successive lords of Akizuki family of Kuroda Clan resided until Meiji Period.
The castle’s main gate, Kuromon, is still remaining and the area is known for its fall foliage.
The ruins of Akizuki Castle is a historical site dating from Kamakura Period.
