The Osaki Channel Crossing is a power line crossing over Seto Inland Sea south of Yoshina, Takehara in Japan, which was built in 1997 and runs from Chugoku Electric Power's Ozaki Power Station at 34°15′26.4″N 132°52′25.1″E / 34.257333°N 132.873639°E / 34.257333; 132.873639 to the Japanese Mainland at 34°18′19.6″N 132°52′29.1″E / 34.305444°N 132.874750°E / 34.305444; 132.874750, with two water crossings: the Nagashima Sector, connecting the Power Station to Usujima, with a span width of 1603 metres, and the Yoshina Sector, which spans from Usujima to the mainland at 2145 metres long.[1] At a height of 223 metres, the towers of the Yoshina Sector are just 3 metres shorter than those of the Chūshi Powerline Crossing, making them the second-tallest electricity pylons in Japan. The pylons follow a barrel design with 3 crossbars.

These sectors are part of the greater Osaki Thermal Power Line, which links the main power station with the Kurose Substation by a 220-kilovolt transmission cable.[1]
