Kōshū Kaidō · Stage 14
By Kami-Suwa to Shimosuwa, where the Kōshū road ends at the Nakasendō: 11.9 km, +97 m.
Best season: Spring and autumn; the Sasago pass road closes in winter. No body manages the old road or publishes a walking season: the month table below is from climate normals. Most of the road is on town streets and main roads; in winter the Sasago pass holds snow and its road is closed to traffic. Before you go

Make it your trip
Every day ends at or near a railway station, but from Saruhashi to Fujimi most of them have no place to stay nearby: base yourself in Ōtsuki for the passes, in Kōfu for the basin, and in Kobuchizawa or Kami-Suwa for the last days, and ride the JR Chūō Line to and from each day's ends. In Tokyo, Fuchū and Hachiōji have hotels by their stations.

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. Daylight is for the 15th of each month. Hut, transport and park seasons are separate: check them for your dates.
Before you go
Arrange your stays, food and travel first, then check conditions again near departure.
Most of the road is urban or follows main roads with traffic: keep to the pavements, and where a road has none, walk facing the traffic. Through Hachiōji the old road is the national highway.
The old road on OpenStreetMapBlack bears live in the mountains along the road: Hachiōji city lists its western mountains, where the Kobotoke pass is, as bear habitat, and Hokuto city recorded a bear 1.3 km from Hinoharu station on 9 September 2026, with sightings from late June to late November. On the pass and hill days carry a bell or radio, walk in company where you can, stay off the paths at dawn, dusk and after dark, and check the cities' sighting pages before you go.
Hachiōji city: bears and hikersMost of the road is asphalt with little shade, and the Kōfu basin (days 9 to 11) is among the hottest places in Japan in July and August. In summer start at first light, carry more water than you think, and rest through midday.
Kōfu (climate table, Wikipedia)The Kobotoke pass (day 4, 548 m) and the Sasago pass (day 8, 1,096 m) are mountain paths and old roads, with no shops between the stations. The prefectural road over the Sasago pass closes every winter to walkers as well as cars (in 2025/26 from 15 December to mid-April): in that season take the train from Sasago to Kai-Yamato.
Kōshū city: winter closure of road 212Getting there
Travel around Chino to Shimosuwa.
Google Maps journey searches, not confirmed services. A mountain endpoint may need a booked transfer or an additional walk.
The walk starts at the Nihonbashi bridge in central Tokyo, by Nihombashi and Mitsukoshimae subway stations and a short walk from Tokyo station.
Kōshū Kaidō (Japanese Wikipedia)The JR Chūō Line follows the road from Hachiōji to Shimosuwa, and the Keiō Line in the Tokyo suburbs: every day of this guide ends at or within about 1 km of one of their stations. At the smaller mountain stations, check the timetable before you set out.

Route & sources
The line is the old road as mapped on OpenStreetMap (relation 9561988, 甲州道中, planet of 27 September 2026), 215.9 km from Nihonbashi to Shimosuwa, mostly on town streets and main roads; through Hachiōji the old road is the main road, walked on its pavements. The days end at railway stations on or near the road, most in its old post towns: TrailSplits chose them, not an authority, and the walking times are our estimates.
