A part of the company name “MEC” comes from the initial letters of “Mitsubishi Estate Company,” and MEC Design International offers interior designs utilizing the experience and technical abilities the Mitsubishi Estate Group has cultivated and network.
The initial letters of “MEC” are our key words: “Mind,” “Environment,” and “Creation,” and we create interior designs that meet the needs of the times.


We believe what is required for interior design now is people- and environment-friendly aesthetic and comfort.
To accomplish this, rich experience and knowledge, flexible ideas and credible technical abilities are required.
MEC Design International has pursued better interior designs since our establishment, in 1972 as a member of the Mitsubishi Estate Group.
We have been offering consistent services from designing and consulting to construction/installation centering around “design & production”
We will continue to meet customer needs as well as contribute to the realization of a truly desirable society through interior designs of office buildings, hotels, hospital facilities and residences.
