MHI History

Back to Company

A history you can trust

Mitsubishi Heavy Industries has delivered engineering excellence for over 130 years across three main industries: power systems, industry & infrastructure and aircraft, defence & space.

Dating back to 1870, our company demonstrated its aptitude for innovation in engineering early on, becoming an established full-scale marine transportation company by 1874. This expertise took us into several industries and propelled us into a household name by 1911.

Turning our expertise to air conditioning in Japan 1953, we introduced our first units to Australia in 1975 through a local distributor and established our first company in 1999. Through our successful operations in Australia, we steadily grew as a division of Mitsubishi Heavy Industries, and eventually spanned off as Mitsubishi Heavy Industries Air-Conditioners Australia in 2009.

The MHI focus is on developing world-class, highly efficient and energy saving air conditioning systems that offer comfort and reassurance to our customers. The expansion of MHIAA has allowed the company to provide a more diverse range of products to the Australian and New Zealand markets and provide comprehensive support to our partners and homeowners through our presence in all major and regional areas.


The “MITSUBISHI MARK” was created by Yataro Iwasaki, the founder of Mitsubishi, in the early Meiji period. The original mark combined sankai-bishi (three lozenges) which is the family crest of the Iwasaki family and mitsu-gashiwa (three oak leaves) which is the family crest of the Yamauchi family in Tosa Clan.

The mark which we know today was used for the first time in an English business brochure of a Mitsubishi limited partnership corporation in 1910.
