I believe the artist was Saro Onishi of Shigaraki-yaki. If I'm mistaken, I apologize. It is definitely a Shigaraki-yaki piece, but please consider the artist information as a reference. We will not accept claims based on incorrect artist information. I haven't been able to use this because I thought it was too precious, so I'm putting it up for sale. I think I've used it a few times.
