CEO – Sou Hashimoto

“Hydrogen, with its antioxidant properties, becomes a key player in promoting health.”

” I want to ensure that patients can regularly consume hydrogen water.”

These words, received from a physician, marked the beginning of the Doctors’ Man initiative.

Guided by the company’s foremost mission to create an environment where high-concentration hydrogen water is affordable and can be consumed correctly, we embarked on the development of our unique hydrogen water server.
Since then, as pioneers in the field of hydrogen therapy, we have continually researched and developed various technologies to improve our products and expand our lineup based on customer feedback and diverse applications.

Currently, our Hydrogen productss are installed in various locations, including fitness clubs, hospitals, clinics, offices, factories, construction sites, stores, and even professional sports venues, steadily spreading the network of hydrogen water stations.
In recent years, hydrogen’s effectiveness for health has become increasingly established academically through numerous clinical studies and research papers.
Taking these circumstances as a foundation, we consider them as evidence and, as a company, are fully committed to promoting the use of hydrogen for medical and lifestyle purposes.

While Hydrogen is utilized and spread rapidly and widely around the world, we believe our role is to develop and manufacture the products based on scientific facts (evidence based medicine)”
We are also committed to cooperating with Development Center of Keio University School of Medicine, and intend to expand high-quality products around the world.
We will continue to work together as a company to drive product development that meets the demand for hydrogen applications in various fields and contribute to the further dissemination of hydrogen
The heartfelt sentiments of the aforementioned physician have fueled our passion, and by giving shape to that passion, Doctors’ Man has gradually grown as a company.
Believing in a future where everyone around the world can be consistently healthy and live longer, we will continue to embrace challenges in our pursuit of growth and success.
