Corporate profile

Origin of the company name

H-one was born through the merger of Hirata Technical Co., Ltd., and Hongo Co., Ltd., in April 2006. The company name represents the will to strive toward the realization of dreams by “bringing together (as one)” “the wisdom (eichi in Japanese)” of Hirata and Hongo employees united. “H” (pronounced as eichi in Japanese) also comes from the initials of both companies: “HIRATA” and “HONGO.”
The trade name of the new company was sought and selected publicly based on the principle that it should be determined by the ideas generated by employees, and was selected from among 260 applications. The history of H-one started with the aim of creating a new company culture and to be a company that can respond with speed and flexibility to the demands of our customers around the world.
