Kaigyokusai Masatsugu (1813-1892) is known as one of the greatest craftsmen of netsuke toggles.
In this 4-square cm clam-shaped ivory netsuke, he recreated the view of Amanohashidate (Bridge to Heaven), one of the three most scenic spots in Japan, by engraving. This microscopic world changes its view based on the visual angle, showing pine trees with various shaped boughs and people enjoying sailing.
Despite the delicate carving, which is too small for everything to be recognized by the naked eye, each motif perfectly holds its shape. This amazing work is just like a microcosm within a clamshell.
