1. Toyama, Japan
You have probably seen these images all over the internet. They are indeed of the Tateyama Kurobe Alpine Route near Toyama, Japan. The route is carefully built so that the surrounding environment is not damaged. Consequently, three lines go entirely under tunnels. (This is also to protect the lines from snow.) Among them are two are trolleybus lines and these are used to prevent exhaust fumes from melting the snow.
2. Aomori City, Japan
Aomori and its surrounding area are renowned for heavy snowfall, the heaviest among all Japanese cities, and, in fact, among the heaviest in the world. The particularly heavy snow is caused by several winds that collide around the city and make the air rise and cool, resulting in quick, thick cloud formation followed by intense precipitation.
