Gosho Dam (御所ダム, Gosho damu) is a multipurpose dam on the Shizukuishi River, a branch of the Kitakami River in Morioka, Iwate Prefecture, Japan, completed in 1981.

[1] Gosho Dam is the fifth of five large dams created in the Kitakami River valley for irrigation, industrial water, flood control and electric power generation under the aegis of the Ministry of Construction.

The project was strongly promoted by the government from 1954, although plans for a dam in the area for the purpose of flood control had been drawn up in 1941.

The dam was completed in 1981 by a joint venture of the Kajima Corporation with Nishimatsu Construction.

The Gosho Reservoir created by the dam is a popular vacation location due to its ease of access to the metropolis of Morioka.
