The waterfall theme is very popular. One sees it very often in Japanese paintings. The waterfall is a symbol of the duality of persistency and change. Hokusai painted his waterfalls abstractly. It seems that the water is flowing right out of a bowl, a giant blue moon.
The second picture shows a couple on a bridge visiting a waterfall of Nikkô, a famous sightseeing spot in the north of Tôkyô. This painting is more naturalistic. Although the water flows down in giant streams, there is no danger for the two people.
The third painting shows a little waterfall in autumn, this could be one in a Japanese garden. The fourth example is another Hokusai painting, where the water stands like a concrete wall.
