For more than 100 years since the company's inception, Hoyu has invested untold efforts in research and development. Upholding our ability to continually release products that are routinely heralded as "unprecedented" is a fusion of a solid foundation of research data and ultra-modern technology.


One in eight Hoyu employees works in R&D.

What makes us unique and alert is that our development is always based on the customer’s viewpoint. With more than 10% of Hoyu’s staff working in the R&D department, we have gathered and analyzed decades of knowledge and data about the beauty and health industry. Paired with our advanced technological capabilities, our R&D facilities are among the best in the industry. Our research covers a broad spectrum of topics such as hair-dyeing mechanisms, color science, manufacturing technologies, improvement of safety, the development of the most up-to-date technology and product testing. With our unique new technologies and commitment to our consumers, Hoyu has set many of the standards in the hair coloring industry.

Product Development

Customer satisfaction and environmental responsibility are our top concerns.

Our General Research Institute currently comprises the following three laboratories. The Basic Research Laboratory conducts fundamental research on the mechanism of hair coloring and product safety; the Applied Research Laboratory develops products incorporating state-of-the-art technologies; and the Research Management Room develops easy-to-use packages and conducts product testing. While maintaining close contact with our sales, production and other sections, the Research Institute devotes efforts toward consolidating the market status of the products, which bear our own brands. At the same time, it is focusing on study for the development of even safer, more usable and environmentally safer products.


New Technologies support our dedication to our founding principles.

Development of new technology, uncompromising production systems, and substantial monitor testing enable us to create new products.


Although Hoyu is a centenarian, we remain true to our founding ideals as a manufacturer: providing safe and high-quality products to consumers at the right time and place. Our dedication to this ageless tenet has allowed the company to amass a formidable wealth of exclusive, expert knowledge. By imposing high standards on ourselves and making effective use of futuristic technology, we at Hoyu have earned the trust of consumers in Japan and throughout the world.
