If light can reach the lakebed, submerged aquatic plants can generate oxygen through photosynthesis, enabling bacteria on the lake floor to purify the sludge. Based on this idea, I designed an architecture that delivers light to the depths of the lake.

This structure is not merely an environmental device; it also reinterprets the memory of the village above the water through light. The image is of Tomata Village, slightly closer to the sky, re-emerging as a shimmering landscape on the lake’s surface—its presence carried by light rising from below, inheriting and transforming the memory of what was once there.
