Our only factory is in Japan.
Our factory has no smokestacks because we melt raw materials with electricity. This unique technology — the first of its kind in Japan — is cleaner and safer for the surrounding community and workers in the factory. Learn more about where HARIO glass was born.

We do our best to protect natural resources.
HARIO heatproof glass is made from 100% natural, earth-friendly material. All glass left over from the production process is recycled into raw material or used to make glass wool insulation if printed on. By carefully protecting natural resources, we are helping to realize a sustainable society.
