In Japanese bathhouses, you can often see murals with Mt. Fuji motifs. In fact, the murals of the bathhouse have "three taboos", that is, monkeys, sunsets and autumn leaves are generally not painted.
This is because, in Japanese, "ape (monkey)" is pronounced the same as "going る (離)", which is easily reminiscent of "客が去る (guest leaving)", the sunset is reminiscent of business falling, and the autumn leaves are reminiscent of deficits, neither of which is a symbol of auspiciousness.
Correspondingly, people generally choose auspicious patterns such as the rising sun or pine trees, the most popular of which is Mt. Fuji. However, because the temperature in the bathhouse is high, there are generally no warm color murals painted on the walls, so the "red Fuji Mountain" against the sun is not too common in the bathhouse murals.
