JOHMON ART was held as part of the Onahama International Environmental Art Festival 2022 at the Aquamarine Fukushima Environmental Aquarium in Iwaki. Feeling the nature in the Jomon no Sato area, which reproduced the environment of that time, I thought of creating a pattern on the surface of the water with a waterfall. By placing a structure on the water surface, which is rippled by the waterfall, to quieten the movement of the water surface, a visual contrast was created. The aim was to create a 'pattern' on the surface of the water. This experimental work changes the scene by altering the movement of the water.
