Drinkware born from 100 years of craftsmanship and science.

The history of HARIO, Japan’s only domestic heat-proof glass maker, began with its production of laboratory instruments.
Through repeated trial and error, HARIO achieved the accuracy, durability and practicality demanded of rigorous laboratory experiments and earned the trust of researchers around the world.
In 2021, to mark the 100th anniversary of our founding, we condensed the laboratory equipment expertise we developed early on to create a new series of "Crafts Science" drinkware.
This drinkware embodies the history of HARIO by melding our advanced processing technology, craftsmanship and functional scientific design.
Coffee making is a science. When someone grinds beans, boils water and extracts coffee, the taste greatly varies depending on the amounts, temperatures, timing and instruments used.
Spout sharpness, operational stability and molding precision all make a difference.
The scientific thinking HARIO developed at its inception now makes it possible for perfectionists to achieve their ideal flavor.
