The autumn leaves of Tateyama are unique in that they aren't just red and yellow, but offer a variation of colors such as the dark green of Japanese stone pine trees, the light green of broad-leaf bamboo trees, and so on.
From the observation deck on top of Kurobe Dam station, you can gaze at the Tateyama mountain range before you and the exciting display of water discharged from the Kurobe Dam. You'll notice how the changing of leaf colors starts near the top of the mountain and they slowly work their way down to the Kurobe Dam, creating what is called the "Three Steps of Autumn".
Take a walk through a truly unique autumn scenery
Tateyama is filled with the red and yellow leaves of fall, plus the dark green of Japanese stone pine trees, the light green of broad-leaf bamboo trees, and more, making it a rare scenery worth seeing.
The red leaves of the Japanese rowan trees, and the yellow leaves of both the mine maple and stone birch trees begin to appear in the end of September around the mountain summit and slowly work their way down the mountains until the beginning of November. If you time your visit right, you can see "Three Steps of Autumn". The peak of the mountain is white with snow, the middle is filled with red and yellow leaves, and below them are the remaining green leaves.
This area is even more impressive when you realize that the Kurobe Dam is an overflow-type dome arch dam, located 1,470 meters above sea level, and is the tallest in Japan at 186 meters. It even discharges 10 to 15 tons of water every second!
Standing on the observation deck on top of Kurobe Dam station and gazing at both these views is guaranteed to take your breath away.
