Visit Toyama's snow corridor of Tateyama Kurobe Alpine Route, near Murodo Terminal. It is a place where you can feel as if you have truly gone to another place. We can surround ourselves with walls of snow, breathe the crisp mountain air, and enjoy a walk down the snow valley. The snow walls near Murodo are open for walking each spring. This year the walkway officially closed June 10th, but you can pass through other areas with snow throughout June. I went up there May 12th.
The snow walls were as high as 15 meters that day. Oh, bring a hat to protect you from the sun and to keep you warm if needed.
