Before the bullet trains and the expressways, before neon and megacity sprawl swallowed the horizons, there was the road. The Nakasendo – “the road through the mountains” – was one of Japan’s Gokaidō, the five ancient highways radiating from Edo, the city we now call Tokyo. For centuries, daimyō lords processed along its packed-earth surface, their retinues stretching for miles; pilgrims moved through cedar shade toward mountain shrines; merchants carried silk and lacquerware between the capitals. The road was the country’s circulatory system.

Much of Japan has changed almost beyond recognition since those feudal processions. But in the valleys of the Central Alps, where the Kiso River has carved deep between forested ridgelines, the Nakasendo endures. Post towns – juku – that once existed to house and feed travellers stand largely intact. Their dark-timbered facades, sake breweries and family-run inns feel closer to the Edo period than to the Tokyo of today.

Walk Japan has been pioneering guided walks along these routes for decades, and its flagship Nakasendo Way tour remains the gold standard: an eleven-day journey from Kyoto to Tokyo, beginning in the cultural capital and ending in the gleaming modern one, with the Central Alps in between. Small groups (never more than twelve) walk with an expert Walk Japan Tour Leader who provides the historical and cultural context that transforms a hike into something far more rewarding. Nights are spent in rural ryokan, traditional inns, with evening meals drawing on locally foraged mountain vegetables, fresh-water fish from nearby streams, and the deep, earthy flavours of Japanese countryside cuisine.

For those with less time, the Nakasendo Way: The Kiso Road distils the experience into five days in the Kiso Valley – the most scenically and historically concentrated section of the full route. The walk reaches the high alpine Kaida Plateau before descending through post towns where time has moved at a different pace. At the end of each day, onsen thermal baths offer the particular kind of restorative quiet that only deep mountain Japan provides. Walk Japan offers deep insight and lasting memories in one of the world’s most distinct cultures.
