KOSHI means waist and MENTORI means scraping off in Japanese. As the name suggests, the bottom side of this bowl is boldly and rhythmically scraped away. And the inside and a portion of the outside is covered with beautiful white glaze. The light brown color of the clay emphasizes the warm atmosphere. The harmony and contrast of natural clay and the noble white glaze are very unique.

This Matcha bowl is made in the kiln of Shigaraki, which is one of the six major old Japanese kilns. The texture of the clay is the most essential characteristic of Shigaraki Yaki ware, creating its natural, simple style. The soil of Shigaraki is used for this bowl to emphasize the texture. Therefore, you can feel the rough texture of the clay itself.

While imagining the completed form, Eizan Okuda, who is the craftsman of this work, carefully shapes and characterizes this bowl by trimming, using specialized tools to create MENTORI scraping off form, considering the usability, thickness of the glaze, and so on. KOSHI MENTORI silhouette adds boldness and a dynamic impression to this bowl.

The warm and rough surface of this bowl is coated by the white glaze. To emphasize the beauty, glazed in white, the artisan Eizan Okuda controls the firing time on purpose to produce warm and calm colors. The dynamic shape of this bowl and elegant white glaze are well balanced, and create a sophisticated atmosphere. When designing this piece, he considered the balance of color between the inside of the bowl and the green Matcha that will one day grace its surface.

He is also particular about the details of design. There is a round portion that is not glazed inside the bowl and the rim of the bowl is lined by trimming tools which is called KUSHIME pattern since it looks like it has been combed by KUSHI Japanese hair comb. Each design is matched very well, therefore this bowl is very attractive. You can feel his attention to detail.

Its form and size fit perfectly into both hands when drinking Matcha and it is lighter than it looks. The artisan and tea master Eizan Okuda designs his works not only to have a beautiful appearance but also for functionality in the tea ceremony.

To consider the time and care, it is set at quite a reasonable price. This will deepen in atmosphere over time. Please enjoy your green moment with this Matcha bowl, which will enrich your tea time!
