1990-2002 Developing Advanced Technology Linking Humans and Machines Together

Kenji Ekuan, the founder of the GK Design Group, was involved in the design of many Yamaha products since the company’s earliest days and clearly remembered these words of Yamaha Motor founder Genichi Kawakami: "A motorcycle fitted with an engine is not a true motorcycle until it is made into something beautiful. What this means is that a motorcycle connects with people through its beauty." Atsushi Ishiyama, who long served as the president of GK Dynamics, explains the concept in this way: "Because you straddle a motorcycle to ride it, it produces a unique feeling of being one with the machine. An instinct for riding horses has been inside us since ancient times-to race across the open plains, to chase game, to conquer. A motorcycle reproduces this instinct through the union of man and machine. It is precisely because it is a motorcycle that man and machine become as one. The machine itself is a source of the eternal raw energy sought by the human soul."

In 1991, Yamaha condensed these concepts and began using the term "humanonics." This word was coined by Yamaha to mean human-oriented technology and connote ergonomic engineering that takes into account human senses and feelings. Ergonomics has traditionally been connected to the structure and positioning of the body, but "humanonics" extends beyond that to encompass senses and feelings.

At certain times and situations, the human body is unconsciously and reflexively controlled by autonomic nerves unrelated to the person's will. Humanonics technology involves measuring and assessing these human rhythms and biological fluctuations and applying that data to product development. Yamaha initiated wide-ranging research in this area by launching the Humanonics Research Group, which is led by the Technology Development Division.

Also in 1991, as this research was being advanced, the humanonics concept was further extended, crystallizing into the new term "trinics." Trinics refers to the fusion of the three areas of mechanics, electronics, and humanonics. It subsequently became a pillar of Yamaha's engineering strategy, as the company laid out a clear policy of incorporating human comfort into the production of better products.

At the Tokyo Motor Show in 1997, Yamaha presented technology that appealed to the senses, centering on the theme of sensuality between rider and machine, and in 2002, it combined the words "human" and "machine" to form the term "humachine," further enhancing Yamaha's philosophy since its founding-the stimulation of human sensibility.

Since that time, humachine technology has been defined as the core element in actualizing Yamaha's mission of being a “Kando Creating Company” and has constituted an important theme in the company's product development activities.
