Suncheon Castle, also known as Suncheon Waeseong (Hangul: 순천왜성, Japanese: 順天倭城), in Korean, Juntenjō (順天城) in Japanese, is the only remaining Japanese castle in Jeollanam-do, and the battlefield of Yi Sun-sin who tempted Konishi Yukinaga from here to Noryang Point known as Battle of Noryang Point.
The castle was built by the Japanese generals Ukita Hideie and Tōdō Takatora as an outpost during the second invasion of Korea in 1597. The castle was constructed using mud and stone with a footprint of 120,600 m2 for the outside castle (Hangul : 외성) 2502m for the inside castle (Hangul : 내성) 1342m. The site consists of 3 outside mud castles (Hangul:외곽성 or 토석성), 3 main stone castles (Hangul: 본성 석성) and 12 castle gates. It is the only castle preserved among 26 Japanese castles in the southern region.
The Japanese general Konishi Yukinaga stayed in this castle with 14,000 troops to fight on two occasions against Joseon and Ming (China) allied forces.
