The evening sun sinks down into the sea of clouds, marking the end of a long day. We call this the magic hour, because it's the time of day where the mountain scenery looks its absolute best. Feast your eyes on the grand spectacle performed by the sky and clouds as they gradually shift between orange, pink, red, and purple.
With luck, you can see a rainbow appear at this time over the Tateyama Mountain Range, opposite the sunset.

The time of the sunset at Murodō-daira is standard for this part of the world, although it changes somewhat depending on the place you are looking from.
