This is an ice-cut sake cup, a representative work of Ryukyu glass made by Moriyasu Inamine, the former master of the Chubu Glass Studio Niji in Yomitan Village, Okinawa Prefecture, and a modern master craftsman. Originally, the crack pattern that appeared as a manufacturing failure was boldly brought to the surface, making it very popular among the works created by Moriyasu Inamine. Moriyasu Inamine has already passed away, and the studio has been passed on to his son, Seiichiro Inamine. Therefore, the Ryukyu glass made by Moriyasu Inamine as new products is only available in the stock on the market. Our store can no longer purchase Ryukyu glass made by Moriyasu Inamine, so it is offered at a premium price. Please be aware of this. Although counterfeit Ryukyu glass is rampant, our store's Moriyasu Inamine Ryukyu glass has the character "吉" (yoshi, meaning good luck or auspicious) carved on the bottom to indicate that it is genuine. #️⃣RyukyuGlass #️⃣MoriyasuInamine #️⃣Okinawa
