Hidden Kii Peninsula - Hatenashi Mountains: Walking the Kohechi Shugendo Trail

The Hatenashi Mountains, lying near the border of Wakayama Prefecture and Totsukawa Village in Nara, form the mountainous area crossed by the Kohechi, the most rugged of the five Kumano Kodo routes. The vast range continues so far it is described as endless, and it has long been known as a training ground for shugendo ascetics. This is a journey through a true hidden region wrapped in deep silence and an air of prayer.

Highlights: The Kohechi, a Path of Prayer Linking Koyasan and Kumano

The Kohechi connects Koyasan (Wakayama), the sacred center of Shingon esoteric Buddhism, to Kumano Hongu Taisha over about 70 kilometers, the Kumano Kodo route with the greatest elevation change and demanding the most stamina. The route crosses three passes near a thousand meters in elevation, and the section over Hatenashi Pass is especially demanding, opening onto a rigorous yet beautiful world of mountain pilgrimage: moss-covered stone-paved paths, abandoned villages, and clusters of jizo statues standing on the heights. Walking it through to the end brings a deep sense of accomplishment.

Hatenashi Hamlet: The Sky Village

Hatenashi Hamlet, midway along the Kohechi, is a small settlement on a mountainside height. Stone Kannon statues modeled on the Saigoku 33 pilgrimage are dotted along the stone-paved road, and the scenery against terraced rice fields and mountains is a spectacle called the village in the sky. Chosen for the 100 Best Villages of Japan, it is a place photographers long to visit. A distinctive charm is how the old road passes right through the yards of private homes, and a signpost reading World Heritage Kumano Pilgrimage Route Kohechi greets travelers at the eaves.

Enjoying the Seasons

Early summer with fresh greenery brings vividly shining trees and comfortable hiking. In autumn (roughly late October to November), the mountains take on color, spreading a brocade landscape together with the terraced fields. Winter carries the risk of snow and ice and suits advanced hikers only. On clear days from spring through autumn, an early-morning visit to Hatenashi Hamlet can reveal the dreamlike sight of a sea of clouds filling the valleys.

Access and Basic Information

To Totsukawa Onsen, route and limited-express buses run from Osaka (Kintetsu Yamato-Yagi Station) and the Shingu area. Hatenashi Hamlet and Hatenashi Pass are basically reached on foot from Totsukawa Onsen. Crossing the passes of the Kohechi is genuine mountain hiking, so prepare full hiking gear, trail food, water, and maps, and plan conservatively working backward from sunset. Confirm escape routes and lodging in advance.

Practical Travel Notes

The Kohechi is among the most demanding Kumano Kodo routes for fit hikers, with almost no shops or vending machines along the way. Water, food, rain gear, warm clothing, a map, and a headlamp are essential. Mobile-phone reception is absent in many sections, so tell family or your lodging your itinerary. If visiting only for Hatenashi Hamlet, it can be reached in a short round trip from Totsukawa Onsen. Totsukawa Village, spreading at the foot of the range and large in area, has three hot springs: Totsukawa Onsen, Kamiyu Onsen, and Tosenji Onsen, all free-flowing from the source and ideal for easing hiking fatigue. The village is also known for its declaration of source-flowing hot springs.

A Word of Advice

The Kohechi is a route for advanced hikers, demanding real stamina and preparation in exchange for its sense of accomplishment. If walking the full route is difficult, a day trip to visit only the spectacular Hatenashi Hamlet still fully conveys the charm of the sky village. After hiking, easing the body in Totsukawa's source-flowing hot springs is the classic finish. Mountain weather changes quickly, so do not overreach and plan with safety first.
