Hario has been dedicated to the design and production of quality heatproof glass since it founding in 1921, and currently operates the only heatproof glass factory in Japan today. Hario has began its history as a manufacturer of laboratory glassware. In 1964, we expanded our production to household items, starting with the coffee syphon. We also began producing lenses for automotive headlights in 1980. Today, Hario continues to make a variety of items, from microwave-safe kitchenware and coffee and tea implements, to aromatherapy and pet products.
