Dossuyama

Dossuyama [安水山 どっすやま] is a city located in southern Mikei Prefecture. As of 2022, it has a population of around 64,000. 
The area of present-day Dossuyama was part of ancient Namema Province, and later Sanzama Province. The well-known Sakadate Temple, which stands in the city centre, claims to have been founded in the year 951. It is also believed that a castle, known as Dosumizu, also once existed in the area during the 12th century, but was later ruined or destroyed. In 1341, Ya'on Castle was built just outside the town by the Omiya clan, taking advantage of Dossuyama's position on the border with Eiita Province. Sakadate Hot Spring, one of the oldest resorts in the prefecture, was founded in 1389.
From the 15th through to 18th centuries, Dossuyama was known as a popular koman.
== Geography ==

Dossuyama is known for having a very cool climate, much like the other southern Mikei municipalities. During the winter months, large amounts of ice and snow can greatly interrupt daily life in the city.

Dossuyama has a mixed economy, dominated by light manufacturing of electronics, automotive components and food processing. Agriculture is dominated by rice cultivation on the flatlands and goat, horse and sheep rearing in more hilly areas.
