The one and only place
for the continual
creation of new value

Mitsui & Co. and Mitsui Fudosan have decided to name the project "Otemachi One." This name symbolizes the characteristics of the development area as a place for the convergence of various people and talented individuals, and as the one and only focus for the continual creation of new value from the Otemachi 1-Chome District to the world. There will be a grand opening for the Otemachi Mitsui Hall and a shopping area with approximately 30 commercial outlets. At the same time, Mitsui & Co. will relocate into its new Head Office building. Subsequently, the Four Seasons Hotel Tokyo at Otemachi will open. Thereafter, tenant companies will begin to move into the development in phases.
