The listed woods include tochi, keyaki, pine, cherry, inu-enju, mulberry, katsura, sen and ginkgo, or lumber with equivalent qualities. Keyaki and tochi appear especially often: keyaki is hard and weighty, with lively grain, while tochi resists deformation and works well as a base for lacquerware.
Before a piece reaches the lathe, a craftsperson judges the outside of the log and chooses material for the intended object and dimensions. The choice is concrete: hardness, weight, grain, deformation risk, lacquer compatibility and the eventual size of a tray, bowl or serving vessel all matter before the first rough cut.
