Onagawa Nuclear Power Plant, Nuclear power plant in Onagawa and Ishinomaki, Japan
Onagawa Nuclear Power Plant is an energy facility located on the Pacific Ocean coast in northern Japan, operating three reactor units. The station sits on a coastal site where the ocean plays a key role in the plant's cooling systems.
The plant was built in the 1970s and underwent extensive safety reviews and upgrades after the 2011 earthquake and tsunami. A 14-meter protective seawall helped shield the facility from severe flooding during that event.
The plant's location on Oshika Peninsula connects industrial development with traditional Japanese coastal landscapes near Minami Sanriku Kinkazan Quasi-National Park.
Access to the facility is limited since it is an active industrial and security-sensitive site. Interested visitors should check in advance about any available tours or viewing areas.
During the 2011 earthquake and tsunami, the plant opened its gymnasium to shelter displaced residents and distributed supplies to the affected community. This action showed how industrial infrastructure can serve local needs during emergencies.
