| Explanation | This is commonly known as a Jomon pochette. It is very rare to find a three-dimensional shape of a woven basket, and is representative of the Jomon period. The inner bark of the cypress family is used in the Ajiro-weave technique, which is still used today. Walnut shells were found in the bark baskets. |
