Our company’s roots lie in Marunouchi where our predecessor, Marunouchi Architectural Office, first opened its doors in 1890 during the early days of modern Japan, and our Mitsubishi Ichigokan project formed a starting point for the development of this district of Tokyo. Ever since then, we have been involved in the ongoing development of Marunouchi as the in-house design office for Mitsubishi Estate Co., Ltd. and as a member of the local community, while also building a strong track record in design and supervision throughout Japan. Working from the multiple perspectives of building owners, users, and managers, our professionals carry on a tradition of design excellence accumulated over more than a century. Today we apply this expertise to projects right across Japan.
Just as the Marunouchi district constructed by our forebears 120 years ago still maintains its vitality, the buildings we design today will create a link to the 22nd century. As a comprehensive construction design company, we will do our utmost to meet the needs of the construction and urban development sectors. Leveraging the experience, ideas and technology that are our heritage, we will continue to meet the challenge of creating a new era in design.
