Naruse Dam is a trapezoidal CSG dam certified as a river structure as part of the Omono River System River Improvement Project, and is the largest multipurpose dam in Japan, the first to exceed 100m in height. Naruse Dam is located in one of the snowiest areas in the Tohoku region, and because pouring cannot be carried out in winter, pouring of CSG and concrete is limited to a seven-month period from mid-April to mid-November. For this reason, the construction of the embankment, the largest of its kind in Japan, was undertaken as quickly as possible while ensuring quality and safety. In this article, we report on construction examples to date, since the pouring of CSG was completed in 2024.
