Toyama Prefecture sits on the Sea of Japan coast of central Honshu, framed by the dramatic Tateyama mountain range and the deep waters of Toyama Bay. Home to the Tateyama Kurobe Alpine Route, one of the world's great high-mountain crossings, and the UNESCO-listed gassho-zukuri thatched-roof villages of Gokayama, Toyama pairs alpine scenery with a coastline famous for firefly squid and glass shrimp, plus a proud tradition of glassmaking and sake brewing in its historic port town of Toyama City.
Toyama faces the Sea of Japan on Honshu's north-central coast, backed directly by the towering Tateyama mountain range, and has a humid climate with one of the most dramatic seasonal swings in Japan. Winters (December–February) are cold, grey, and among the snowiest of any populated area in the country, thanks to moisture-laden winds crossing the Sea of Japan and colliding with the Northern Alps. Summers (June–August) are hot and humid with a pronounced tsuyu rainy season in June–July. Spring and autumn are Toyama's showcase seasons, framed by the snow-capped Tateyama range visible from the city itself on clear days.
