It took 8 months for the order to arrive!! I've never used it and it's been stored away. Yamada Katouen, a pottery workshop established in 1794 (Kanei 6) in Mino, a historic pottery production area dating back to the mid-Heian period, has been making pottery such as suribachi (mortar) and oroshiki (graters) for generations. This is a suribachi made by the 7th generation, Tomoya Kato. Thank you for looking.
