Round chip box. Also called magemono (bent round object). This is a utilitarian liquid storage container or kurimono (hollowed out object), used since the Yayoi-era and before the invention of the oke (tub) and taru (barrel). Magemono were made by bending thin boards of hinoki (Japanese cypress) or sugi (Japanese cedar), softened by heating or soaking in hot water, into a circle, then using rice glue to attach a bottom board with strips of cherry or birch. Magewappa (sugi only) is the dialectic word for magemono. This is one of most beautiful wooden crafts of Japan.
