Kumiko is a traditional Japanese wood assembling technique that has been used in Shoin-style architecture. The tray is designed with kumiko to produce a gorgeous environment for dinners and parties. Only Akita cedar, a high-end Japanese wood, is used for the WA-ZEN.
Traditional Japanese designs, such as Asanoha and Gomae are embodied into the Mitsukude Kumiko. The Hyakunen Monogatari 2020 version of WA-ZEN features shaved corners to make the original WA-ZEN trays even more sophisticated.
