Shimane Prefecture lies along the San'in coast of western Honshu, home to Izumo Taisha, one of Japan's oldest and most revered Shinto shrines, and Matsue Castle, one of only twelve original castles remaining in the country. Known in Japanese mythology as the land where the gods gather each October, Shimane blends ancient shrine culture, samurai heritage, celebrated gardens, and a quiet, uncrowded coastline far from Japan's typical tourist circuit.
Shimane faces the Sea of Japan on Honshu's San'in coast and has a humid subtropical climate with a distinctly different rhythm from Japan's Pacific side. Winters (December–February) are cold, grey, and considerably snowier and wetter than Tokyo or Osaka at the same latitude, due to moisture-laden winds crossing the Sea of Japan. Summers (June–August) are hot and humid with a pronounced tsuyu rainy season in June–July. Autumn brings typhoon exposure but also Shimane's most culturally significant season, Kamiarizuki.
