Tateyama-Kurobe Alpine Route
This tour route goes through the Northern Alps, lined with mountains over 3,000m above sea level, stretching 37.2km, and the difference in altitudes from the foot to the top is up to 1.975m.
Every April when the route opens, tons of tourists flock here. Even though the journey involves crossing mountains and a lot of travel, it's all worth it just to see the Snow Corridor.
