I believe this is Arita-yaki (Arita porcelain). Diameter: Approximately 19 cm The gold-rimmed green design is beautifully drawn, and the overall appearance is refined and elegant. I once thought about using it, but I couldn't use it all, so it went into the cupboard. There are no chips or cracks, and the condition is good. I hope someone who can use it well will consider purchasing it.
