Nagano Prefecture sits in the heart of the Japanese Alps, a landlocked mountain region of central Honshu famed for hosting the 1998 Winter Olympics. Towering peaks, deep valleys, and pristine highland plateaus define the landscape, while centuries-old temples, historic post towns along the Nakasendo highway, and legendary onsen hot springs reveal a culture shaped by isolation and resilience. The prefecture stretches across five distinct mountain ranges, offering year-round outdoor pursuits from ski slopes at Hakuba and Shiga Kogen to summer alpine trekking through Kamikochi and the Northern Japan Alps.
