Corporate history

Our Japan Headquarters established Macau Branch and Hong Kong Branch in 1982 and 1984 respectively to start the business in Great China areas. In order to facilitate the work registration in Mainland China on project-basis, a subsidiary named Hong Kong Limited was established in 1994 to assist the same. Since Takasago Constructors & Engineers (Beijing) Co., Ltd. was established in 2003, this subsidiary took over the Mainland China business and Takasago Hong Kong and Macau Branch was closed after transferring the Hong Kong/Macau business to Takasago Thermal Engineering (Hong Kong) Co., Ltd.


Currently our engineering department is handling two main streams of engineering works which consist of cleanroom/laboratory construction and general heating, ventilation & air-conditioning system installation. Other supporting departments include accounting, project administration and technical administration. A new business department also launched in 2018.
