Mitsui Fudosan Co., Ltd.

Mitsui Fudosan announced the start of construction today of the Yokohama Mitsui Building (tentative name) under development in the Minato Mirai 21 area of Yokohama. Construction is scheduled for completion on December 31, 2011.

As Mitsui’s largest office building in the Yokohama Station area and the first “Mitsui Building” in the region, this project is expected to serve as Mitsui Fudosan’s flagship tower in the locality. The building is strategically situated in block 67, the northern gateway to the Minato Mirai 21, and the nearest to Yokohama Station.

Kanagawa Prefecture and Yokohama City have introduced a proactive system into the Minato Mirai 21 area for attracting enterprises, and the area is expected to develop as a center for headquarters of major companies. The area is also becoming a hub of business, commerce and cultural facilities; the Nissan Motor Co., Ltd. head office building, Fuji Xerox Co., Ltd. R&D facility and the Shiki Theater Company’s “Cats Theater” can all be found in the vicinity of the Mitsui Fudosan project.

The Mitsui Fudosan Group has a long track record of contributing to the Yokohama area through its office building businesses such as the Yokohama Shin Kannai Building and Yokohama Creation Square, commercial facilities business such as Mitsui Outlet Park Yokohama Bayside, Mitsui Fudosan’s first outlet mall in the Kanto Region, and LaLaport Yokohama, and through its residential housing business with condominiums such as Park City Kanazawa Hakkei, Park Tower Yokohama Station Premier, and its Fine Court series of detached urban housing. Mitsui Fudosan is committed to assisting the future development of the Yokohama area by continuing to provide spaces that bring affluence and comfort.
