Presented at the reconstructed Jōmon landscape “Jōmon no Sato” at Aquamarine Fukushima, this work inserts a contemporary phenomenon into a recreated ancient environment.  Focusing on ripples generated by a waterfall, a structure was quietly placed upon the water’s surface. The intention was not to block the waves but to soften and slightly redirect them. As a result, new patterns emerge—subtly different from the original. Natural rhythm is maintained, yet minute differences appear. Reflections of light and surrounding scenery blur the boundary between natural and artificial. Through minimal intervention, a dialogue between water and structure unfolds.
