Founded in 1921
For over 100 years, we’ve been making products that customers cherish.
HARIO has been planning, manufacturing and selling heatproof glass since its very inception — and is the only manufacturer with a heatproof glass factory in Japan.
Initially, we manufactured and sold laboratory glassware.
But in 1948, we began making coffee siphons by taking advantage of the properties of heatproof glass and our refined glass processing techniques.
We later expanded into a wide range of popular home products made from various materials.
Since the 1980s, we’ve been producing industrial glass for automotive light lenses.
We also offer items for coffee and tea (black, Japanese and herbal),
as well as microwave-safe cooking utensils and other kitchenware.
In the next 100 years, we want to continue enhancing the lives of everyone who loves HARIO and keep creating products that people consider their favorites.
We strive to be environmentally friendly.
HARIO’s heatproof glass has been manufactured without smokestacks since 1972 thanks to unique technology that melts glass using electricity instead of oil. The environmentally friendly process was ahead of its time and proved that glass factories didn’t have to be smoky and dusty. Our pollution-free factory doesn’t affect the local environment and provides a comfortable workplace for employees.
Products and services that earn long-term adoration.
For over 40 years, HARIO has been replacing product parts such as broken glass bowls and stained tea strainers. This is one of the reasons our customers stay loyal for so long. We highly value product designs and services that customers continue to love for decades.
