Ryukyu Glass

Brief Summary and History

Ryukyu glass is manufactured by experienced glass artisans who blow each piece of glasswork by hand.

Early glass production in Okinawa dates back to 1910, when merchants from Kagoshima prefecture founded a company known as Okinawa Glass Works in Naha City. At that time, main products manufactured were practical, clear glass items such as lamp chimneys, medicine bottles, pickling jars and fly traps. While factory premises were lost in the ravages of WWII, glass production quickly resumed with postwar economic recovery. As Okinawa came under American military rule, glass production gradually shifted to reflect American demand for colorful glass souvenirs, tableware and ornaments. Export routes with America and the Japanese mainland were established, leading to dramatic expansion of the company’s market share. After the reversion of Okinawa to Japanese control, the production of Ryukyu glass evolved to cater to the needs of tourists from mainland Japan. Production methods, materials and product designs were improved and developed based on traditional glass making techniques, leading to a diverse range of products spanning multiple genres. Amongst them include popular, well-known signature designs such as molded glass with vertical lines and spiral patterns, intentional decorative cracks known as “ice cracks,” as well as various types of “bubble glass”. Ryukyu glass, which is made using discarded glass bottles and raw glass, was officially designated as a prefectural traditional craft product on June 12th, 1998.
