Route Overview
The Kamikōchi Norikura Forest Road (officially: Nagawagawa–Azumi Line and Kamikōchi Norikura Super Forest Road) is a scenic mountain route in Nagano Prefecture, stretching approximately 35.1 km from Nagawa Onsen (Kurokawado) to Azumi (near the Kamikōchi entrance at Nakanoyu).
The road is divided into three sections:
- Section A: Nagawa Onsen → Norikura Highlands (approx. 15.3 km)
- Section B: Norikura Highlands → Shirahone Onsen (approx. 6.7 km)
- Section C: Shirahone Onsen → Nakanoyu (approx. 13.1 km)
Note: Section C is currently closed due to bridge damage from an avalanche, and has been inaccessible for several years as of 2025.
The entire road has been toll-free since 2008, and offers magnificent alpine scenery across different elevations.
Recommended Route
The best riding experience is found on Section A (Nagawa Onsen to Norikura Highlands) or Section B (Norikura to Shirahone Onsen).
Section A features steadily climbing curves with panoramic views as you ascend.
Please note that Section C remains closed, so complete through-routes are not currently possible.
Road Conditions & Safety
The entire route is paved but narrow in many sections, with steep gradients, sharp curves, and several long tunnels.
This is a typical mountain road, requiring cautious driving.
There are also rockfall warning zones, and winter closures are in effect from mid-November to late April.
Always check road conditions in advance due to frequent weather-related changes.
