The Yuki no Otani, often colloquailly called the Tateyama-Kurobe Snow Wall or Snow Corridor, is arguably the most iconic view of the Tateyama Kurobe Alpine Route, a tall ice wall that is typically 7m tall, and can go up to 20m tall in years with heavy snowfall. The Yuki no Otani is at its tallest when the route just opens in mid to late April. The snow wall becomes progressively shorter as the year goes on, and in some years, you can still see some snow even in July or August.
The Yuki no Otani is formed simply from clearing the snow off the road in order to let the Tateyama Highland Bus pass through from Murodo Terminal to Bijodaira Station. Since the snow naturally piles up between 7m to 20m, simply digging a path through the snow creates this incredible sight.
