This is a teacup by Ryōichi Hashiba, a Mino ware artist. It has a texture similar to Shino ware, and while it is bold and rustic, it also has a certain stylishness. The market doesn't seem to highly value his work, but I believe this piece is a good one. I am selling it to organize my collection. Please check the condition in the photos before purchasing.
