Japanese Glass Identification Guide + Gallery

Back to Glass Encyclopedia Home

There is currently not all that much known about the Japanese glass industry, but more and more quality pieces of glassware are appearing, bearing Japan labels. Not just new glass, but vintage pieces from around 1950's - 1970's, the quality and style of which rivals Murano, Scandinavian, and Czech glass production.

Iwatsu Glass

Iwatsu Glass Co. was, and still is, based in Osaka, Japan. They produced colourful art glass during the 1970's, the quality and style of which matched, and is often mistaken for, Italian Murano glass and Czech glass from the same era. From labelled pieces found online, they seemed to have had two main ranges or brands, which were "Hineri", and "Art Glass".
