Tateyama Kurobe Alpine Route — Murodo to Ogizawa via the Northern Japan Alps Snow Corridor
Snow walls 20m high. Japan's alpine impossible.
The Tateyama Kurobe Alpine Route is one of Asia’s most surreal mountain experiences — a 37-kilometer crossing of the Northern Japan Alps that combines a roster of transport modes with one genuinely drivable road segment between Ogizawa and the Kurobe Dam. The snow walls at Murodo, sometimes reaching 20 meters at opening in mid-April, are the kind of thing you have to see to believe. Kurobe Dam itself, the tallest arch dam in Japan at 186 meters, sits at the route’s heart and is accessible by a 6.1-kilometer pedestrian tunnel. The drivable Ogizawa spur road is the overlander’s entry point on the Nagano side, and it’s worth doing in a high-clearance rig if you want to push as far as gates allow before the mixed-transport section takes over.
This is not a full drive-through in any conventional sense — sections use ropeway, trolley bus, and funicular. The drivable Ogizawa approach is straightforward in good weather, but snow can close it until late April or May. Best season is May through November; the route closes entirely in December. No technical 4WD required for the road portion, but mountain weather is fast and unforgiving. Fuel in Omachi before you go — there’s nothing at altitude. Permits not required for the road access, but the transit crossing costs money and planning. What you get is Japan’s version of an alpine expedition, with vending machines at the top.

Frequently asked questions
Can I drive my own vehicle the full route, or is it all transit?
Private vehicles are prohibited on most of the route — you'll use a combination of electric buses, cable cars, ropeways, and tunnels operated by the Alpine Route. The Ogizawa access spur is the main segment where your own rig is relevant, and high clearance helps there on gravel.
When do the snow walls actually peak, and is the route open year-round?
The snow corridor peaks in mid-April to early May when walls can hit 20 meters. The route runs May through November — it closes entirely in winter due to extreme snowpack and avalanche risk.
Are there permits or fees to travel the Alpine Route?
No permit required, but the transit tickets are not cheap — expect to pay ¥9,000–¥13,000+ per person depending on how much of the route you cover. Book through the official site at alpen-route.com, especially for the May snow corridor season when it sells out fast.
What's the hardest or most committing part of this crossing?
The Murodo plateau section at 2,450m (9,839 ft) is the crux — weather shifts fast, visibility can drop to near zero in fog or storm, and you're fully exposed with no quick exit. The altitude hits some people hard too; headaches and fatigue are common if you're ascending quickly.
Is there anywhere to camp along the route, or do I need to book lodges in advance?
Dispersed camping doesn't exist here — the route runs through a managed alpine corridor with mountain huts (sanso) that book out months ahead for peak season. Murodo has the most options including Murodo Terminal Hotel; book well in advance or plan to base in Omachi or Tateyama and day-trip.
