In the late 16th century, a new art was developed in the Japanese garden; that of "ōkarikomi" (大刈込), the technique of trimming bushes into balls or rounded shapes which imitate waves. According to tradition this art was developed by Kobori Enshū (1579–1647), and it was most frequently practiced on azalea bushes. It was similar to the topiary gardens made in Europe at the same time, except that European topiary gardens tried to make trees look like geometric solid objects, while "ōkarkikomi" sought to make bushes look as if they were almost liquid, or in flowing natural shapes. It created an artistic play of light on the surface of the bush, and, according to garden historian Michel Baridon, "it also brought into play the sense of 'touching things' which even today succeeds so well in Japanese design."
