As the light bulb industry automated, Shotoku Glass shifted to manufacturing glassware, concentrating on the production of mouth-blown glasses of several thousand kinds. Shotoku Glass is most known in Japan for their “Edo glass” – a small beer glass that is admired for its handiness and delicate strength, earning a high reputation within top restaurants and the hospitality industry. With a long and rich experience in mouth-blown glasses, Shotoku Glass has succeeded in creating an ideal series of very thin glassware.
