Hario is a Japanese company founded in Tokyo in October 1921 by Hiromu Shibata as Hiromu Shibata Works. Initially, Hario manufactured and sold laboratory glassware. The name Hario comes from the Japanese words for glass (玻璃, hari) and king (王, ō), thus meaning "King of Glass". Yasuhiro Sibata is the current Chairman & CEO, and Tadayasu Sibata is the President.
Hario expanded into household items in 1948, starting with the coffee siphon. The company is the only heatproof glass manufacturer in Japan with its own factory. Hario further expanded its product line to include microwave-safe kitchenware, coffee and tea implements, aromatherapy products, and pet products. The V60 dripper, known for its V shape at a 60-degree angle, was developed in 2004 and has gained popularity worldwide. Recent news includes the V60 Brewers Cup 2025 and the introduction of the Hario Bloom series with sustainable packaging. Hario products are known for their design, functionality, and ergonomics, making them popular among baristas and coffee lovers.
