Nagano Hiking & Trekking Guide 2026

Where to walk in Nagano — from easy half-days to serious treks, with honest difficulty grades.

By Updated Reviewed by Daniel Mercer

Nagano has 10+ hiking trails covered in this guide, led by Kamikochi Valley Floor Walk, Togakushi Okusha Inner Shrine Trail and Tsubakuro-dake (Swallow Peak) Summit. Each entry below includes the practical details — what it costs, when to go, and how to plan around it.

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.
