Higashidōri Nuclear Power Plant, Nuclear power facility in Shiranuka, Japan.
Higashidōri is a nuclear power facility located on the eastern side of the Shimokita Peninsula in Aomori Prefecture, facing the Pacific Ocean. The site contains reactor units with cooling systems that use seawater, and includes separate buildings designed for equipment maintenance and heat exchange operations.
Construction of the first unit began in 2000 and was led by Toshiba, with completion finished in 2005. This was a significant project for Tohoku Electric and marked a turning point in the region's nuclear energy development.
The plant represents Japan's response to the energy crisis of the 1970s, when the nation decided to secure its power supply through nuclear energy. It reflects how such facilities became part of the country's industrial landscape.
The facility is located in a coastal region and can be reached by roads that pass through Aomori Prefecture's landscape. The site is visible from a distance, but access to the operational areas is restricted to authorized personnel only.
The facility uses a specialized cooling system that combines seawater with heat exchangers to optimize reactor cooling efficiency. This design shows how nuclear plants are adapted to coastal locations to make use of available natural resources effectively.
