This is a hand-blown glass from Ryukyu glass, made by Moriyoshi Inamine, the former master of the hand-blown glass studio Niji in Yomitan Village, Okinawa Prefecture, and a modern master craftsman. This beautiful hand-blown glass, reminiscent of the Okinawan sea, is a valuable piece of Ryukyu glass by Moriyoshi Inamine, which is no longer available in the market. This is one of the last four pieces of the popular clear glass. Moriyoshi Inamine has already passed away, and his son, Seiichiro Inamine, has taken over the studio. Therefore, the only new Ryukyu glass made by Moriyoshi Inamine available is the stock currently in the market. We can no longer purchase Ryukyu glass made by Moriyoshi Inamine, so it is offered at a premium price. Please be aware of this. Although counterfeit Ryukyu glass is prevalent, our Moriyoshi Inamine Ryukyu glass is genuine, as indicated by the character "吉" (Yoshi) carved on the bottom.
