The Symphonic Sculpture by Gabriel Loire (1904–1996) is one of the highlights of the Hakone Open-Air Museum in Kanagawa Prefecture. The museum spreads across 70,000 square metres of lush green garden space and was the very first outdoor gallery in Japan!  Marvel at the dazzling light as you ascend the 18-metre tall spiral staircase to look out on the grounds of the museum and across the mountains
