Mitsui Fudosan announces completion of Roppongi T-Cube, a modern, multi-purpose office complex in the fast-developing Roppongi area of Tokyo

Octorber 10, 2003
Mitsui Fudosan Co., Ltd.

Mitsui Fudosan Co., Ltd. (“Mitsui Fudosan”), in cooperation with Samsung Japan Corporation (“Samsung Japan”), has completed construction of Roppongi T-Cube, a large-scale private development located in the Roppongi area of central Tokyo. The completion ceremony for the building was held today. The building is a multi-purpose complex, incorporating serviced apartments (luxury furnished residences) and commercial facilities around a core of leased office space.

The Roppongi area, known for its international flavor, is currently the site of many large-scale development projects, and is increasingly looked at as a new business center. Located in the heart of this vibrant area, Roppongi T-Cube has a direct connection to “Roppongi 1-chome” subway station, and is convenient to two other subway stations, Tameike Sanno and Roppongi.

The modern design of the outer façade is open and bright, incorporating glass, aluminum, and a variety of other materials to produce a look well suited to the location. Glass, natural wood and granite are used to create an elegant, inviting foyer that provides continuity with the surrounding areas. The three-story open lobby, four-meter-wide sidewalks and elevator directly to the subway station not only make the building more open, safe and convenient, but add to the vibrancy and high-class image of the area.

The standard floor in the office area has 1,727sqm (18,590sqft) of column-free space, permitting an efficient and comfortable layout. Many features, detailed in the attached specifications, have been incorporated to meet the demands of today’s leading international corporations. The lower floors contain restaurants, cafeterias and a convenience store, supporting the office workers and providing them with a safe, comfortable and efficient work environment.

The upper floors contain serviced apartments (scheduled to be available from January 2004) managed by Oakwood Japan. These 54 units are the most elegant of Oakwood’s properties in Japan, and include a luxury penthouse on the top floor. They are ideally suited to international executives in Japan for mid- to long-term stays.

The Roppongi T-Cube project makes effective use of land held by Samsung Japan and other companies. The total land area was consolidated into a real estate trust by The Chuo Mitsui Trust and Banking Company, Limited, with beneficial interest acquired by Samsung Japan, Mitsui Fudosan and a special purpose company. Capital for the construction was raised through nonrecourse financing from Sumitomo Mitsui Banking Corporation. This arrangement allowed Samsung Japan to both acquire space for its head office and increase its earnings with leasing income, without additional investment. Mitsui Fudosan provided a portion of the funding, as well as undertook management of all aspects of the project, including development and planning, acquiring the necessary permits and approvals, management of the construction, leasing to tenants, and management and operation of the finished building. The solutions and services provided to the building clients by Mitsui Fudosan also helps enhance the added value of the property.

Tenants confirmed for the property include, in addition to Samsung Japan, Fuji Xerox Co., Ltd. and Fuji Xerox Learning Institute Inc. Despite the threat of the so-called “2003 problem” (an abundant supply of new office space in Tokyo) the property has achieved full capacity. Several international high-tech firms have also established offices in the surrounding area, raising expectations for a new high-tech oriented business district.
