GEN-NAI’s dream of a lifetime comes true

1.GEN’s life started in the sky.

“I felt that human beings had been flying in the sky long ago.”

Yanagisawa Gen-nai (hereinafter called “GEN-NAI”) is the Project Owner and Developer of the GEN H-4 Project. Of course, GEN-NAI did not mean that people had feathers on their back and were therefore able to fly in the sky. For him, flying in the sky cannot be considered as an almost unattainable desire, as it is in fact an act broadening the horizons of everyday life.

< As a child, he felt the sky as very close; as an adolescent, he learned how to fill him up with new energy >

GEN-NAI was born in Matsumoto, Nagano Prefecture, in 1932. Like other great engineers, in his childhood he used to break down several things in his house, making all the people around him quite annoyed.
In that period, the city of Matsumoto welcomed many people evacuated from Tokyo due to the WWII bombings on Japan’s biggest cities. The city also hosted several factories which built airplanes, and some of his relatives were pilots: therefore, it was quite natural for him to think he would have been a pilot in the future.

The WWII defeat represented for Japan a significant turning point, which marked GEN-NAI’s passage to adolescence.
In the aftermath of the war, GEN-NAI enrolled into the Department of Mechanical Engineering at the University, where his ability and easiness in assembling and disassembling things and his remarkable engineering studies were highly admired. So much so that he was appointed as Assistant at the University of Tokyo once graduated.

At that time, the University of Tokyo was one of the center gathering and analyzing information on the latest internal combustion engines from all over the world. During his period there, he also had the possibility to build up, for instance, aircraft engines. Working as Assistant at the University, he was also offered a training period in several corporate manufacturing sites, in which he had the opportunity to experience first-hand how combustion engines were built.

After spending two years in the best environment for further deepen his engineering knowledge and skills, he participated as a system engineer in a project aimed to produce a motorcycle as high-quality as the BMW motorcycles, which at the time were the best in the world. He was appointed to the development of not only the engines but also the gear boxes, being required to work not only on the design of effective top-tier products, but also on the development of the tools required for their production.
Thanks to this two-year period, GEN gained a remarkable experience as engineer, and even afterwards he kept developing engines for industrial and agricultural machinery, as well as aircraft engines in Tokyo.

< Back to his hometown, he started approaching the sky >

For GEN-NAI, a turning point was represented by the return to his hometown, Matsumoto. Even after he came back there, people used to place him orders for mechanical designs. After his return, he founded Engineering System Co. in order to solve technical problems which could be found in the manufacturing and research process. In the Suwa areas, where precision machinery and electronics industry had become popular, people made use of his deep knowledge of engineering, and the machine developments he created contributed to the commercialization of several innovative technologies. Engineering System Co. has made a name for itself as a credible, unique company that can meet the demand of solving manufacturing process for production machineries’ problems from numerous leading companies. Therefore, we can say that GEN-NAI opened a new chapter of his engineering life.

2. GEN-NAI’s dream flies higher and further.

< The creation of the GEN 125 engine >

In 1988, Engineering Systems Co., Ltd., which had offered several engineering consultancy services to a lot of different companies, created its own product: a compact, lightweight, high-power GEN 125 engine. Produced thanks to years of experience accrued by Yanagisawa GEN-NAI as a specialist in internal combustion engines, this horizontally opposed 2-cylinder, 10-horsepower and 125 cc engine weighs 3.5 kg and his overwhelming performance heavily contributed to the development of GEN-H4, the smallest manned helicopter in the world.

< The time has come >

At the very beginning, the purpose of the development of this engine was the unmanned flight transport of a rice bag (60kg). In GEN-NAI’s imagination, this carrier would have automatically followed the route of its owner while he moved, representing a sort of a new industrial revolution – far more convenient than the use of bogies, carriages or trucks, this vehicle is in fact a true flying machine, a noticeable leap forward in technology.
Just in GEN-NAI’s feeling, it would have become a natural ability for human beings to control flying with such a device, making them feel closer to the sky.

< A new challenge for the unmanned air transport >

The development of an unmanned air transport vehicle in the 1990s was quite impossible, as no infrastructure was in place to support it. Therefore, GEN-NAI took a very engineer-like approach to develop a safe, durable and reliable aircraft such as the GEN-H4, a manned helicopter based on four GEN 125 engines and a coaxial-rotor. Following the demonstration flight at the Oshkosh Air Venture in 1998, the experimental manned product became world-famous as GEN-H4.
As of today, GEN-H4 can carry a total loading amount of 120kg, twice the initial target – which, unsurprisingly, was a 60-kilo rice bag.

< Time to fly >

Unlike the 1990s, in 2019 the infrastructure required for unmanned transport is in place – it is now therefore time to give new life to GEN-NAI’s project, an unmanned air carrier which could make people feel closer to the sky.

3. GEN-NAI’s dream beyond individual to social.

< He wanted to make everybody feel the sky as their own >

In 2019 New Year’s Day, GEN-NAI made a solemn promise to the sky. Back in the days, his dream was strongly linked to the development of human society. In recent times, it is all the more so: his project can in fact be used as a relief tool in the event of a disaster – e.g. earthquakes or floods. GEN-H4 can actually get off anywhere. It can easily carry heavy supplies. And there is no worry about possible secondary damage, as it is unmanned.
GEN-NAI focused on the values of “Corporate Social Responsibility”. He is now attracted by the idea of “Sustainable Development Goals”, as the air transport system represented by GEN will prove to be an unparalleled relief tool, as well as being open to other safe, reliable uses according to the developers and customers’ needs.

GEN-NAI’s dream can represent a true aid instrument for society – this is why his heart is full of hope and joy.
