Kurume-jou, or Kurume Castle, was once built in Sasayama-machi, Kurume, Fukuoka Prefecture.
The castle originated from a fortress made by a local clan during the period of Eihyou Era (1504 ~ 1521). It is believed that it was after Toyotomi Hideyoshi conquered Kyuushyuu region that the castle was renovated extensively using a more modern building technique by the order of Kobayakawa Hidekane in 1583.
In 1620, the castle was given to Arima Toyouji as recognition of his contribution to the victory of Osaka no Jin Battle.  Since then, until the end of Edo Period, the castle was occupied by the Arima family, the lord of Kurume Clan.
The Chikugo River ran along the Northwest side of Kurume Castle and it functioned as a natural  protective moat and the castle was built making the most use of other natural geographical advantages to protect it. The castle compound had seven castle towers with  two or three stories soaring above high white stone walls. Among them, the three storied Tatsumi castle tower, the main castle in the southeast corner, was the most imposing and impressive.
Now only the stone wall remains and inside the castle compound are Sasayama Shirine, worshipping the Arima lord, and Arima Kinenkan Museum that exhibits  reference materials related to the Arima family.  
Kurume Castle is an old castle ruin that is also designated as a prefectural cultural asset.
