Miraishin no Oka, the Hill of Eternal Hope is a sculptural work located on a hill above Kosanji, the somewhat bizarre temple located on Ikuchijima along the Shimanami kaido that connects Hishu with Shikoku.
I have posted about it before, the link is here Heights of Eternal Hope for the Future
All the statues and in fact the surface of the hill top, is constructed out of Carrera marble from Italy where the Japanese sculptor, Kazuo Kuetani lives and works.
I revisited it while on my second day walking along the Shimanami Kaido, a route most often cycled by visitors.
