This place is written as [豊平峡ダム] in Japanese.

Hoheikyo Dam, located in Jozankei, Minami-ku, Sapporo, is one of the most renowned sightseeing spots in the city.

Situated upstream of the Toyohira River, it serves as a vital water source for Sapporo’s domestic use. Standing at 102.5 meters tall and spanning 300 meters wide, Hoheikyo Dam is an arch-type concrete dam of the ‘concrete dome arch dam’ variety.

This type of dam is rare in Hokkaido, with Oku-Shimukappu Dam on the Shimukappu River being one of the only other examples. The dam creates Lake Jozan (Jouzan-ko), a picturesque destination known for its vibrant autumn foliage, situated within the scenic Shikotsu-Tōya National Park.

History

The Toyohira River, flowing through Sapporo, was historically prone to flooding, especially during heavy rains in the Meiji era. To mitigate this, the Hokkaido Development Commission undertook a project to straighten the river’s course. However, after World War II, Sapporo’s population surged rapidly, leading to increased demands for water and power. Despite efforts to manage flooding, incidents still occurred during spring snow melts and heavy rains.

In response, the Hokkaido Development Bureau formulated plans to construct a dam to both prevent floods and enhance electric power supply. The construction of the Hoheikyo Dam took place between 1965 and 1972, coinciding with the Sapporo Winter Olympic Games. At that time, Sapporo’s population had reached one million (now 1.92 million), underscoring the dam’s critical role in supplying water and electricity to the growing city.

After the completion of the Hoheikyo Dam, Sapporo’s population continued to grow, necessitating further infrastructure development. Consequently, another dam was constructed on the opposite side of the Jozankei area, known as the Jozankei Dam. Together, these two dams play crucial roles in supporting the water and power needs of Sapporo’s expanding population.
