A 40-tonne sculpture unveiled late last year beneath the waters of Tokunoshima in Japan waits to be reclaimed by fish and coralOcean Gaia, unveiled late last year beneath the waters of Tokunoshima in Japan, is both a sculpture and a sanctuary. Although monumental at 5.5 metres wide, the work feels intimate, its stillness amplified by drifting light and the quiet shift of currents. The pregnant figure is Gaia, meaning Earth, the mother of life. She cradles her belly as she sleeps. The sculpture is perforated around the edges so that fish and coral can claim it over time.
