A Trail With 1,000 Years of History
The Kumano Kodo is one of only two pilgrimage routes in the world designated as a UNESCO World Heritage Site — the other is the Camino de Santiago in Spain. For over a millennium, pilgrims have walked these mountain trails through the Kii Peninsula south of Osaka, connecting three grand shrines through dense forests of Japanese cedar and cypress.
For trail runners, the Kumano Kodo offers something no purpose-built trail can match — the weight of history in every step. The stone-paved paths have been worn smooth by centuries of feet. Moss-covered stone markers guide you through passes where emperors and monks once walked. The forest is ancient, towering, and deeply quiet.
The Nakahechi Route
The Nakahechi (Imperial Route) is the most popular and accessible path, running roughly 70 kilometers from Tanabe to the grand shrines of Kumano. Most hikers take 4-5 days. Trail runners can complete it in 2-3 days, though the temptation to slow down and absorb the atmosphere is strong.
The trail climbs through mountain passes between small villages, each with its own character. The Takijiri-oji trailhead marks the traditional start, where a torii gate stands at the forest edge and the modern world falls away. The highest point on the Nakahechi is the Mikoshi-toge pass at about 800 meters — not high by alpine standards, but the sustained climbing through dense forest is surprisingly demanding.

The three grand shrines — Hongu Taisha, Nachi Taisha, and Hayatama Taisha — are the spiritual heart of the Kumano Kodo. Hongu Taisha sits in a mountain clearing surrounded by cryptomeria trees, its wooden torii gate the largest in Japan. Nachi Taisha overlooks Nachi Falls, a 133-meter cascade that is the tallest single-drop waterfall in the country. Arriving at these shrines on foot, as pilgrims have for centuries, carries an emotional resonance that arriving by bus simply cannot match.
Onsen Recovery
Japan's onsen culture transforms the Kumano Kodo from a great trail into a transcendent experience. Nearly every village along the route has a hot spring bath — some are centuries-old public bathhouses, others are riverside pools where thermal water meets mountain streams.
Yunomine Onsen, a tiny hot spring village along the Nakahechi, has been in continuous use for over 1,800 years. The Tsuboyu bath, a natural rock pool inside a small hut, is a UNESCO World Heritage Site itself. Soaking in 42-degree water after a day of mountain running is recovery at its most primal and effective.
