Serving as a breeding ground for black-tailed gulls, Kabushima Island is designated as a national natural monument.
Originally a separate island, it became connected to the mainland after the Imperial Japanese Army constructed a causeway in 1942.
Black-tailed gulls fly in to raise their young yearly from March to August.
The island is filled with black-tailed gulls, said to number between 30,000 and 40,000.
In Hachinohe, black-tailed gulls have long been cherished as the messengers of the Japanese goddess Benzaiten (the protector of prosperity and fishing) of Kabushima jinja Shrine, who guides fishermen.
In mid-May, canola flowers bloom on the island.
The yellow of the canola flowers, the red of the torii gate of Kabushima jinja Shrine, the white plumage of the black-tailed gulls, and the blue sky create a beautiful contrast.
