This non-electrified single-line connection between the city of Okayama and the old castle town of Tsuyama in the central mountains between the Inland Sea side of Western Japan and the Japan Sea is 58, 7 km long. From Tsuyama junction there are railway lines to the east and west of the central plateau of Western Japan (i.e. the Kishin-sen to Niimi and to Himeji via Sayo), and the continuation northward across the mountains to Tottori via Chizu (i.e. the Inbi-sen). The Tsuyama-sen follows the Asahigawa River from Okayama up to Fukuwatari and then branches away across the hills to Tsuyama.
Since the opening of the Chizu Kyûkô railway in 1994 the Tsuyama-sen has lost its function as a link between the Inland Sea and the Japan Sea. The line has repeatedly been damaged by stone fall and landslides; part of it had to be closed for 5 months 2006/7, and again in July/August 2018 damage was serious. The region is noted for heavy rainfall, hot and humid summers and cold winters.
The Tsuyama-sen was completed in 1898, the link into Tsuyama town (1, 9 km) in 1923. In 1944 it became part of the national network. Freight services ended in 1987. There are 22 trains (of which 8 are accelerated trains) Tsuyama - Okayama and 24 Okayama – Tsuyama (of which 7 are accelerated trains) Tsuyama – Okayama. In addition, a few trains run only part of the way.
