Tomoyuki Oiwa's black sake drinker who learned pottery under Ryuichi Kakurezaki.
He built a self-designed hole kiln in Kamigori, Hyogo Prefecture.
It is fired with the aim of strong burning, and the high amount of heat changes the black color of the painted soil to a wonderful color, making it a glossy clear black similar to the black of his teacher, Kakurezaki.
In terms of modeling, he pursues the beauty of a three-dimensional object, reminiscent of his teacher, Ryuichi Kakurezaki.
