Senkaku Bay Ageshima Park

Senkaku Bay is one of Sado Island’s most scenic destinations, with five small coves along approximately 1.9 miles of coastline. Its series of cliffs rising nearly 100 feet is said to rival Norway’s renowned Hardangerfjord, and the bay has been selected as one of Japan’s 100 Best Beaches.

Senkaku Bay Ageshima Park is a sightseeing facility offering sweeping views of the bay. Across Machiko Bridge, made famous as a filming location for the Showa-era movie “Kimi no Na wa,” an observation deck on Ageshima Island provides panoramic views of Senkaku Bay. The glass-bottom sightseeing boat has a glass panel in the center of its floor, allowing passengers to see underwater scenery and schools of fish. The cruise also takes passengers close to the dramatic cliffs, accompanied by lively narration. Visitors can also feed the black-tailed gulls that fly alongside the boat.

In 2023, the aquarium in the park was renovated as the Ageshima Sea Digital Museum, where visitors can discover fish found in the waters around Senkaku Bay through state-of-the-art digital displays.

The café serves dishes showcasing ingredients from Sado, including plate lunches with grilled turban shellfish caught in local waters, a Burikko Menchi Burger made with young yellowtail, and a hot dog featuring Sado sausage that won a competition in Europe. The gift shop also sells original park merchandise.
