Chūshi Powerline Crossing, High-voltage cable crossing in Takehara, Japan.
The Chūshi Powerline Crossing is a high-voltage cable installation that spans the Seto Inland Sea, connecting Takehara on Honshū with Ōkunoshima island. The structure uses two tall towers that rise above the water and carry six conductors arranged in three separate levels.
This powerline was constructed in 1962 as a major milestone in Japan's electrical infrastructure development. It was built to establish a dependable connection across the Seto Inland Sea and support the region's growing power demands.
The towers stand as examples of Japanese engineering precision, demonstrating the national commitment to efficient power distribution across geographical barriers.
The structure was designed with adequate clearance underneath to allow ships to pass safely below the cables. Visitors can view the installation from the water or nearby coastal areas and appreciate its scale from multiple vantage points.
The infrastructure spans 2,357 meters between its towers, making them the tallest electricity pylons in Japan, with conductors designed for 645 amperes maximum current.
