Vintage 9 newest piece wood bowl set Japan made

newest This is a vintage bowl set of wood made in Japan. They are all stamped with "Japan" though the script is a bit different between the bowls. They are all a fairly light weight wood in a light color. I'm not sure what kind of wood.

The large bowl measures 9.75 inches across the top and stands a bit under 3 inches tall. The small ones are 5 inches across the top and stand 1.25 inches at the side.

They are all in very good vintage condition.
