1.Kabushima Island

A breeding ground of black-tailed gulls and designated as a natural monument.

From spring to summer, the dazzling yellow rapeseed flowers are in full bloom.

The Kabushima Island is appointed as a natural monument where black-tailed gulls would breed in great numbers. As its name suggests, it was originally an island, but due to extensive land reclamation work during the war, the island is now connected with the main island of Japan.
Since black tailed gulls only mate on cliffs and islands far from civilized areas, in Japan, it is quite hard to observe them breed. Kabushima Island is the only place where people can see up close and watch the nests of these creatures. It is an overwhelming site to see 30 - 40 thousand black tailed gulls from spring to summer along with the rich yellow nanohana flowers or rapeseed flowers.
In addition, 1933 (Showa 8) and plate indicating the amount of inundation of tsunami of 2011 (Heisei 23) which attacked the Sanriku coast are installed in approach to a shrine spreading out to bushimashinsha.
