Company Timeline

1948

The founder of Denyo, Eiza Kuboyama, with a strong passion for rebuilding Japan from its state of ashes, has established Japan Power Welding Machine Co., Ltd., the predecessor of Denyo Co., Ltd. in 1948.

1959

Despite being a small player at that moment of time, the company had a strong vision of a future international market of its very own original products – hence the birth of Japan’s first high-speed engine-driven welders in 1959.

1973

In 1973, Denyo began to manufacture engine-driven air compressors to meet rising market demand. Denyo established itself as the leading company in the outdoor power source sector with its equipment widely used on various large-scale construction projects.

1986

To make a difference, Denyo came up with the invention of the excitation system with a special excitation winding in 1986. This made it possible to not only reduce the number of parts but also to meet diversification in loads of engine generators such as a thyristor, an inverter and so on.

1992

Power generators were increasingly used in events and exhibitions. For such deployments, requirements for low-noise, superior electrical properties and greater mobility were greatly desired.

1997

Denyo responded to changes in regulations with exceptional speed by promptly dealing and complying with the new technical standards, as well as obtaining certification for the JG standard in 1997.

2000

In 2000, Denyo was listed on the First Section of the Tokyo Stock Exchange.Following that, the company expands its global reach by establishing its Singapore subsidiary, Denyo Asia Pte Ltd.

2007

In 2007, Denyo developed the first engine-driven air compressor with variable pressure and speed control system in Japan.

2010

Following the plants in Indonesia and the U.S, Denyo established its third overseas plant, Denyo Vietnam Co., Ltd. in 2010 near the city of Hanoi in Vietnam.

2014

Up till date, Denyo has produced more than 50 models of engine-driven welders in ranges spanning from 30A to 500A.

2017

In 2017, Denyo developed the World’s First Quietest and Smallest Generator, Malie. Registers at just 43dB in sound emission; this piece of engineering marvel represents the culmination of Denyo’s technological breakthroughs in portable power technology for more than 7 decades.
