The "Towada Art Museum" created by artist Rei Naito and architect Ryue Nishizawa is set to be built on a small hill overlooking the Seto Inland Sea in the area called Karato on Toshima Island. Abandoned rice paddies have been revitalized together with local residents, and at one corner of the vast land, a building shaped like a water droplet has been installed. It features a concrete shell structure with an area of approximately 40×60 meters and a maximum height of 4.3 meters, and it contains no columns. Two openings in the ceiling allow the surrounding wind, sound, and light to flow directly into the interior, creating an organic space where nature and the building respond to each other. Inside, a "spring" is born throughout the day. This landscape communicates an infinite variety of expressions with the changing seasons and the passage of time.
