Kumano Kodo Nakahechi · Stage 4
The long day through the mountains, by Kobiro-toge and the Iwagami-oji stretch, reopened on 1 October 2025, to Hosshinmon-oji: about 13.5 km, 6 to 8 hours. No restaurants: bring lunch. From Kobiro-toge there is no water source until the vending machines at Hosshinmon-oji.
Best season: March to May and October to November. Open all year; spring and autumn are the popular seasons, the Tanabe City Kumano Tourism Bureau says, its autumn peak from September to November, though September is among the wettest months on its climate graph. Summer is hot, humid and wet, and typhoons bring floods and landslides: check the weather and ask your inn each morning. From late December to February the passes can have frost and snow, and the days are short. Before you go

Nonaka, strung along the old road around the shrine and the Nonaka Ipposugi bus stop: KUMANO TRAVEL lists 11 places, nearly all with supper. The last beds before Hongu, apart from two in Fushiogami, about 3 km short of it.
A town or village: find accommodation yourself. TrailSplits has not checked what is open.

Trailhead · 327 m

Make it your trip
Takahara, Chikatsuyu and Nonaka have limited beds, mostly small inns with dinner and breakfast, and they fill up in spring and autumn: the Bureau advises booking about six months ahead. Its KUMANO TRAVEL site stops taking bookings 20 days before the night, and a daily luggage shuttle carries bags between inns booked there. Aim to arrive between 15:00 and 17:00.
Three days with nights in Takahara and Nonaka; the last day, 21 km to Hongu, is 8 to 11 hours on the Bureau's times.
Plan this journeyThe last 6.8 km into Hongu (the Bureau's section page says about 7.5; its route map and this line, 6.8), by bus to Hosshinmon-oji: a very popular walk, the Bureau says.

Snow at the high point is estimated with a simple snowpack model from these temperatures and precipitation, not observed; steep islands and high summits can hold more snow than it shows.

Before you go
Arrange your stays, food and travel first, then check conditions again near departure.
Stamp boxes stand at 18 points from Takijiri-oji to Kumano Hongu Taisha, and the credential is free. Walk this route and the Camino de Santiago and register at the Hongu Heritage Center or the Tanabe Tourist Information Center to become a Dual Pilgrim.
The Bureau: Dual PilgrimSummer is hot and wet, and typhoons bring floods and landslides: ask your inn each morning. Mamushi vipers, giant hornets, leeches and ticks live along the way; bears are rare, and the Bureau notes that the attacks in the news are almost all in northern Japan. Put rubber caps on walking-pole tips.
The Bureau: tips for walkingArrive between 15:00 and 17:00 and carry a light, the Bureau says; in December the sun rises about 6:55 and sets about 16:53. The last day to Hongu, 21 to 24 km and 8 to 12 hours with breaks, barely fits that daylight: start at first light, or shorten it by the 7:23 bus from Chikatsuyu-oji (7:29 from Nonaka Ipposugi) to Doyukawa-bashi (about 17 km from Hongu), as KUMANO TRAVEL suggests. From December to March the last bus from Hosshinmon-oji leaves at 14:48.
The Bureau: tips for walkingGetting there
Travel around Tsugizakura-oji to Hosshinmon-oji.
Google Maps journey searches, not confirmed services. A mountain endpoint may need a booked transfer or an additional walk.
The Bureau advises the night before in Kii-Tanabe: from Osaka or Kyoto on the day, even the earliest train and bus leave too little time to reach Chikatsuyu or Nonaka, so only Takahara is within reach, as in the 3-day plan. Buses from Kii-Tanabe station reach Takijiri in 36 to 38 minutes (¥970), from 06:16; in busy seasons the 08:30 and 08:37 fill up, so the Bureau suggests an earlier one. From 19 September to 10 December 2026 an extra express bus leaves Kii-Tanabe at 06:55 for Takijiri (07:27) and Hosshinmon-oji (08:54). A taxi is about ¥8,000.
The Bureau: busesBuses from Hongu Taisha-mae reach Kii-Tanabe in 1 h 35 to 2 h 10 (¥2,100), the last at 16:40; Shingu in 1 h 15 to 1 h 25 (¥1,560), the last at 18:58; and Yunomine onsen in 10 to 15 minutes (¥310).

Route & sources
The Tanabe City Kumano Tourism Bureau gives about 38 km from Takijiri-oji to Kumano Hongu Taisha (its route map of May 2026: 37.1 km), in sections that end at Takahara, Chikatsuyu, Tsugizakura-oji and Hosshinmon-oji. The line here is the route on OpenStreetMap (relation 17094646, planet of 21 September 2026), walked in the pilgrims' direction, 35.9 km, cut at those section ends. The times are the Bureau's section times, which include breaks; its difficulty table gives about 6½ hours of walking for the 21 km from Tsugizakura-oji to Hongu that its section pages put at 8 to 11.
