Okinose W Arch

The Okinose W-Arch is situated on the Etchu-Miyazaki Coast, at the easternmost tip of Toyama Prefecture. Located approximately 1 kilometer offshore, it faces the open ocean. The water remains clear from spring through summer, although occasional strong currents can be encountered. The water depth here is about 15 meters, and the presence of two arches side by side is an exceedingly rare occurrence on the Sea of Japan side. According to local legend, an ancient shrine once stood in this area, making it known as a power spot. Visiting this site is highly recommended.

At the Okinose W-Arch, you can spot a variety of marine life, including big snappers, amberjack, yellowtail, sunfish, peppers, kijihata, aohata, horse mackerel, and more.
