Bonseki (盆石; lit., tray rocks) is the ancient Japanese art of creating miniature landscapes on black lacquer trays using white sand, pebbles, and small rocks. Small delicate tools are used in Bonseki such as feathers, small flax brooms, sifters, spoons and wood wedges. The trays are either oval or rectangular, measuring about 60 by 35 centimeters in size. Oval trays have a low rim while rectangular ones are flat.
