Onagawa Town, Oshika District, Miyagi Prefecture, is known for its nuclear power plant and fishing port.

As a result, the town is still undergoing reconstruction efforts. Onagawa Town's main festivals are the Onagawa Port Festival and the Onagawa Sanma Harvest Festival. The Onagawa Port Festival is held every year on the last weekend of July and attracts many tourists.
