Traditional Okinawan pottery, Yachimun! This fish pattern is called "Gyomon" (fish crest) and is a traditional design that symbolizes the prosperity of descendants and warding off evil. "Yachimun" is the Okinawan word for "pottery." The colors and shapes that evoke the nature of Okinawa become familiar in your life once you start using them, and it's pottery with many fans. The green rim and blue color are cute! Although it is new and unused, please refrain from purchasing if you are nervous about home storage m(_ _)m
