The Kumano Kodo is not one trail but a web of pilgrimage routes that has threaded the forested Kii Peninsula, south of Osaka and Nara, for more than a thousand years. Of these routes, the Nakahechi is the one most walkers choose. It is the “imperial route”, followed by retired emperors and their courts from the 10th century onward, and today it is the best waymarked and best supported section of the network. Since 2004 it has been part of the UNESCO World Heritage listing “Sacred Sites and Pilgrimage Routes in the Kii Mountain Range”, one of only two pilgrimage routes in the world with that status. The other is the Camino de Santiago, and a walker who completes both can register as a “dual pilgrim”.
We walked the Nakahechi over five days in late October and came away with a clear sense of why the route rewards slow travel. It is not high, it is not technical, and it is not remote in the way a Himalayan valley is remote. But the forest, the small shrines and the villages along the way create a rhythm that is hard to find on a modern hiking trail.
The shape of the route
The classic Nakahechi walk begins at Takijiri-oji, a shrine at around 80 m elevation where the pilgrimage path leaves the road and enters the mountains. From here the trail runs roughly 38 km eastward to Kumano Hongu Taisha, the first of the three grand shrines known collectively as the Kumano Sanzan. Most walkers take two or three days for this section, staying in the villages of Takahara and Chikatsuyu, or in the small hamlets around Hongu.
From Hongu, a second stage continues to Kumano Nachi Taisha on the coast, another 27 km or so over two passes called the Kogumotori-goe and the Ogumotori-goe. These names mean the “small cloud-catching pass” and the “large cloud-catching pass”, and the second one lives up to it: the trail climbs to Echizen-toge at about 870 m, the highest point on the whole Nakahechi, before descending steeply through cedar forest to the Nachi shrine and its waterfall. The third grand shrine, Kumano Hayatama Taisha, sits in the town of Shingu at the mouth of the Kumano River, and pilgrims historically reached it by boat.
A trail of oji shrines
What sets the Nakahechi apart from a simple forest walk is the string of oji, or subsidiary shrines, that marks the way. In the medieval period there were said to be ninety-nine of them, and pilgrims stopped at each to pray, recite poetry and make offerings. Many are now only a stone marker under a tree; a few, like Takijiri-oji at the start and Hosshinmon-oji near Hongu, remain active shrines. The name Hosshinmon means “gate of awakening”, and passing it was understood as entering the sacred precinct of Hongu itself.
The stretch from Hosshinmon-oji to Hongu is only about 7 km and mostly downhill, which makes it the most popular half-day on the route. It passes through terraced fields, tea plots and a viewpoint looking down to the Oyunohara sandbank, where the original Hongu shrine stood until a flood in 1889 forced it to higher ground. The sandbank is now marked by a torii gate almost 34 m tall, one of the largest in Japan, and walking beneath it after days in the forest feels like a genuine arrival.
Terrain, distances and daily effort
The Nakahechi is a walking route rather than a mountain trek, but it should not be underestimated. The first day from Takijiri to Takahara is short, around 4 km, yet it gains roughly 300 m almost immediately on rooty, rocky steps. The second day to Chikatsuyu is about 10 km with a pass at around 690 m. The longest single stage, from Chikatsuyu to Hongu, is close to 25 km if walked in one push, and most people either break it with a bus link or accept a long day of eight to nine hours.
Surfaces vary from smooth forest track to ancient stone paving worn slick by centuries of feet and rain. Poles are useful on the descents, especially on the Ogumotori-goe, which drops several hundred metres on stone steps. There is nothing that requires a head for heights, and navigation is straightforward: bilingual signposts appear at every junction, and numbered markers every 500 m let you check your position.
When to walk
The Kii Peninsula is one of the wettest parts of Japan, with more than 3,000 mm of rain a year in the interior. This is why the forest is so lush, and also why timing matters. Spring, from late March to May, brings mild temperatures and fresh green leaves. Autumn, from mid-October to late November, is drier and cooler, with maples turning colour in the valleys. Both seasons are busy, so accommodation in the small villages should be reserved well ahead.
Summer is hot and humid, with the rainy season from early June to mid-July and typhoons possible from August into early October. Walking is still feasible, but the heat on the exposed sections is draining and trails can close after heavy rain. Winter is quiet and often clear; snow is rare on the lower sections but possible on the passes, and daylight is short.
Hot springs, food and the pace of village life
One of the pleasures of the Nakahechi is that the trail passes through inhabited landscape. Villages such as Takahara, Chikatsuyu and the small settlements near Hongu offer family-run lodging where dinner and breakfast are included, and where a bath is waiting at the end of the day. Around Hongu, three hot spring hamlets sit within a few kilometres of each other. One of them, Yunomine, is said to have been in use for 1,800 years and includes a tiny stone bath that is itself part of the World Heritage listing. Pilgrims traditionally bathed here to purify themselves before approaching the shrine.
Meals lean on the region’s produce: river fish, mountain vegetables, pickled plums from the nearby coast, and rice. Vegetarian requests are usually manageable if made in advance. Convenience stores are rare once you leave the roads, so carrying snacks and at least 1.5 litres of water per person for each stage is sensible.
Practical notes and respect for the place
No permit is needed to walk the Nakahechi. Access is by rail to the coastal towns of Tanabe or Shingu, then by local bus to the trailheads, and bus links between villages make it easy to shorten stages. The trail is well suited to walkers with modest experience, but it is worth remembering that this is a living religious route. Shrines are active places of worship, and a small bow at the torii, quiet behaviour in the precincts and staying on the marked path are simple courtesies that local people notice and appreciate.
We finished at Nachi in light rain, with the 133 m waterfall, the tallest single-drop fall in Japan, roaring beside the vermilion pagoda. After five days of cedar shade and stone steps, it was a fitting end to a route that has been drawing walkers to the same spot for a very long time.
