"HARIO" means "King of Glass" in Japanese. The HARIO Group, a Japanese brand, was founded in 1921 and has a century-long history. Initially, it manufactured scientific glassware for physical and chemical purposes. After World War II, leveraging the heat-resistant properties of glass and the glass processing techniques developed from producing chemical products, HARIO ventured into the unknown realm of the household market by creating siphon-style coffee makers. As the sole heat-resistant glass manufacturer in Japan, it stands alongside Corning Glass in the U.S. and Schott Glass in Germany as one of the world's three major heat-resistant glass manufacturers.
