There is a walled alpine route of up to 20 feet of snow in Japan. This is the Tateyama Kurobe. The views are nothing but surreal. This road became operational at the beginning of the 1970s.
To be able to travel all the way, you can use 5 different public transports: cable car, bus, trolleybus, aerial tramway and pedestrian path. The route has been constructed in such a way that it does not harm the surrounding natural environment.
If you want to make stops along the way, there are hotels close to the station, where you can take tours of trekking through the mountains.
Without doubt, walking among the ice is something worth it if you’re in Japan.
