Founded in 1922, Shotoku Glass is a long-established glass manufacturer with a history of over 100 years. Initially, the company manufactured glass for light bulbs, but later shifted to producing glass tableware. By refining the light-blowing method cultivated through the production of light bulbs, in 1989 we completed a glass called ``Usuhari'' that made full use of traditional techniques. It is widely used as a glass that allows you to enjoy alcoholic beverages more delicately and more deliciously, with the least amount of foreign body sensation when the glass touches your lips.
