Bonseki is the Japanese art of creating miniature landscapes on black lacquered trays using sand, pebbles, and small rocks. Small, delicate tools such as spoons, feathers, and wooden wedges are used. It is believed that the practice was invented over six hundred years ago by Japanese Emperor Temmu. Bonseki pictures are transient in nature, and are displayed in tokonoma, or alcoves, in homes. There is believed to be 10,000 people in Japan that still practise bonseki.
