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.
Ordinary days become special when you take the time to relax and savor delicious coffee or tea. See how customers obtain and use HARIO products.
