Hosooka Observatory — photo spot in 22-24 Tatsukobu, Kushiro, Kushiro District, Hokkaido 088-2141, Japan

Hosooka Observatory in eastern Hokkaido is a quiet stargazing spot framed by flat wetlands and dark skies—ideal for wide Milky Way shots and long-exposure nebula scenes when skies clear. Rural surroundings reduce light pollution; nights are cold, and weather changes fast. Best for astrophotography; daytime also offers calm landscape compositions.more
