Section length: 12.8 kilometers; Time required: approx. 7 hours (not including the approach to Mt. Amamizu)
This is a section that often feels like the Trail has entered untouched nature; many giant beech trees can be found around Nonoumi Ike pond. There are many unusual and rare plants in and around Nonoumi wetland. Immediately after the snow melts, iwauchiwa (Shortia uniflora), a very rare flower, blooms here, while in autumn the colors are spectacular. Photography fans will be busy on this section of the Trail!
The starting point for Sections 5 and 6. Crossing highway 403, there is parking space for one or two cars. Vehicles cannot turn at the pass. There is a larger parking lot about 10 minutes by foot from the pass on the Niigata side.
Accessible by vehicles, with a small parking lot for about three cars. There are often road closures in spring due to fallen trees and landslides.
Currently accessible from the Nagano side; the Niigata side has closed due to a landslide. The approach to the Nonoumi camp site is close by here.
The starting point for sections 6 and 7. Unfortunately, it does not provide good views. From here it is about a 45-minute descent to the Mt. Amamizu Matsunoyama trailhead.
Provides parking space for about three cars, and a bio-toilet.
