Tochigi Hiking & Trekking Guide 2026

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

By Updated Reviewed by Daniel Mercer

Tochigi has 9+ hiking trails covered in this guide, led by Mount Nantai Summit Trail, Senjogahara Marshland Boardwalk Trail and Ryuzu Falls to Yudaki Falls Trail. Each entry below includes the practical details — what it costs, when to go, and how to plan around it.

Tochigi Prefecture is a landlocked gateway north of Tokyo where the UNESCO World Heritage shrines of Nikko rise beneath cedar forests, cool highland onsen resorts fill the Nasu plateau, and potters still throw Mashiko-yaki by hand — a prefecture of mountains, waterfalls, and craft traditions found nowhere else in the Kanto region.
