"HARIO, The King of Glass"

Since our founding in 1921, HARIO has been committed to the design, production, and sale of high-quality heatproof glass. We are the only manufacturer in Japan that produces heatproof glass in our own factory.

Originally specializing in laboratory glassware, HARIO expanded into household products in 1948, beginning with the coffee siphon. In 1980, we further diversified by manufacturing automotive headlight lenses. Today, our product range includes everything from microwave-safe kitchenware and coffee and tea accessories, to aromatherapy and pet products.

The name HARIO is derived from the Japanese words for glass (玻璃, "hari") and king (王, "ō"), reflecting our goal to be recognized as the world’s leading glass manufacturer.
