About Sugahara

Pursuing the Possibilities with Glass

Since our beginnings in 1932, in Tokyo, our artisans at Sugahara have applied traditional Japanese design techniques to reveal and express the beauty of glass in ways never before seen, in handcrafted glassware for the tabletop and other uses.

“Glass is alive.” “Communicate with glass.” These expressions may sound funny to you but this is how Sugahara artisans talk about glass. They communicate with glass by observing it and hearing its “voice” every day. As the artisans capture and shape the glass at its key moment – when it is extremely hot liquid – flowing liquid-like forms are created in keeping with the unique consistencies and intensity of the material, and the infinite characteristics of glass are explored and revealed to maximum effect in the end product. 

Our goal is glassware that pleases you when you hold it, and that livens up and brings warmth to your table when you entertain your friends and loved ones.
