Global Philosophy of Inaba Group

Global Philosophy of Inaba Group

At Inaba Group, we are committed to improving the global environment in the fields of energy saving and resource conservation and to creating enriched communities and comfortable spaces for the people who live there.

To realize our global philosophy, Inaba Denko America serves as a point of contact for our partners and users in North America. We ensure hands-on local assistance and business continuity on a long-term basis. Moving forward with our expertise, we strive for further achievements on product development, distribution system and customer relations.



Our initial business began in 1938 and an HVAC division was established in 1978 as Inaba Denko. Our company has maintained an independent operation and the largest market share in Japan since its founding.


Our global network has expanded from Japan to North America, Asia, Oceania, the Middle East, Europe and Africa over the years. We have seen continued sales achievements worldwide.


We have gained a wealth of knowledge and expertise in ductless air conditioning in order to compete in the Japanese market, the birthplace of ductless system, and to expand globally.


Engineering process in design and development is centralized in Japan and customized at each manufacturing location. Quality is dually controlled by the headquarters and each manufacturing location.


We maintain dispersive manufacturing strategy for stable supply and business continuity. That includes three company factories in Japan and one in Thailand as well as partner factories throughout Asia.


We efficiently manage global logistics through our corporate factories and our partners’ warehouses. We utilize distribution centers of our channel partners in the U.S. for faster delivery.
