Sep'o is a kun, or county, in Kangwà Ân province, North Korea. It was created as a separate entity following the division of Korea.
The county is primarily mountainous, and is traversed by the Masingryà Âng and Kwangju ranges. There are numerous mountains outside of these two ranges as well. The chief streams include the Namdaech'à Ân, Yongjich'à Ân, and Komitanch'à Ân (고미ÃÂÂì²Â). 75% of the county's area is occupied by forestland.
Sep'o county is divided into 1 Ã Âp (town), 1 rodongjagu (workers' district) and 24 ri (villages):
Sep'o is host to deposits of molybdenum, silver, zinc, and fluorite. Agriculture also contributes to the local economy; Sepo is particularly known for its radishes. In addition, livestock raising and orcharding play a role, and there is some small-scale manufacturing as well.
