Riwon County (also spelled Iwon) is a county in South Hamgyong province, North Korea. It is located at the province's northeastern tip, and borders the Sea of Japan (East Sea of Korea) to the southeast.
Riwon is mountainous, although there are also small plains, and is home to the Taedok Mountains (대덕산맥). The highest peak is Taedoksan (1,442 m). There are some 10 significant streams; the chief of these is the Namdaechon, which drains into the Sea of Japan. There are various bays and islands along the coast. Thanks to its coastal location, the county enjoys a mild maritime climate. Forestland (70% of which is coniferous) takes up 73% of the county's area.
Mining and manufacturing
Machine manufacturing dominates the local economy, accounting for half of annual industrial production. Deposits of iron, iron sulfide, talc, limestone, graphite, quartzite and silica are found in the county. The Riwon Mine produces talc.
