About Takasago Thermal Engineering

A Legacy of Engineering Excellence Since 1923

The company started as Takasago Heating Works Co., Ltd. in 1923. Until today, the company handled and mastered the art of air conditioning equipment construction and peripheral fields.

Takasago Thermal Engineering Co., Ltd. (TTE), Japan has continued to take on challenges in advanced technologies to become an entity of customer trust and pioneers of optimum systems and equipment.

Since inception, our business objective has been heating-related work, starting with "Entertainment Hall Audience Seating Cooling (Mitsukoshi)" and "Whole Building Heat Pump Air-Conditioning (Kyoto Dento).”

In 1960, when air conditioning became commonplace, and thereafter, we achieved the #1 position in the construction industry, providing comfortable air conditioning systems to buildings such as the World Trade Center, New National Theatre, Tokyo and the National Art Center, Tokyo, and large volume air conditioning systems to buildings such as Tokyo Dome and Kyoto Station.

In addition, we also worked on the Osaka World Exposition venue and Shinjuku subcenter. We have always satisfied customer requirements while fulfilling changes in the society, such as air conditioning equipment for comfortable office environments, industrial air conditioning equipment, and using energy conservation and CO2 reduction technology for the preservation of the global environment.
