Senzu Dam, Gravity dam in Shizuoka Prefecture, Japan
Description
Senzu Dam is a concrete gravity dam that rises across the Sumata River in central Shizuoka, built to harness water for power generation. The structure features a dual spillway system designed to manage water flow and control flooding.
History
The dam was completed between 1930 and 1935 by Hazama Corporation as part of Japan's effort to develop modern hydroelectric power in the region. Its construction reflected engineering advances of the early 20th century in central Japan.
Culture
The dam construction followed the 1906 Meiji government initiative to develop hydroelectric power, leading to collaboration through the Anglo-Japanese Hydroelectric Company.
Practical
The site is accessible via Senzu Station on the Oigawa Railway, which also connects to the nearby Sumata Onsen area. Visitors are best served by arriving during months with stable weather for clear views of the structure and surroundings.
Did you know?
Water stored behind the dam flows downriver to power a generating station that still produces electricity today. This system reveals how the structure remains an active part of Japan's energy network rather than just a historical monument.
