Kōgen Prefecture (江原道, Kōgen-dō) was one of the administrative divisions of Korea during Japanese rule, with its capital at Shunsen. The prefecture consisted of modern-day Kangwon/Gangwon, divided between North Korea and South Korea due to the division of Korea. While each Korea has its own Kangwon/Gangwon Province, the North Korean portion of Gyeonggi and the South Korean portion of Hwanghae have been absorbed into other provinces. Shunsen is in present-day South Korea.
