This is a single-flower vase (or tokkuri, a sake bottle) made of Bizen-yaki, a traditional craft of Okayama Prefecture. The appeal lies in the "yohen" (kiln transformation) scenery created solely by the power of the earth and fire, without using any glaze. Top: You can see the rough "goma" (sesame) kiln transformation, created by the flames and ash. Bottom: You can enjoy the powerful, rustic texture of the earth, characteristic of Bizen-yaki. It's a simple design that blends well with modern spaces. You can use it not only for flowers but also as a tokkuri for sake. Enjoy the changes in appearance that come with use, as the flavor deepens over time.
