In advance of the January 2009 start of construction on the main structure of the Nagatacho Sanno Mori Building in the Nagatacho district of Tokyo's Chiyoda Ward, Mori Building Co., Ltd. held a building–site ground sanctification ceremony (jichinsai) today, Friday, December 19.
This building is located in the Akasaka-Nagatacho area, a business hub. With six subway lines converging in the vicinity, this highly convenient site is only a two-minute walk from the Tameike-Sanno and Kokkaigijidomae Tokyo Metro stations. Bordering on Hie Shrine, the area is also notable for its extensive greenery.
The Nagatacho Sanno Mori Building is an office building rising 8 floors aboveground, with a total floor area of about 5,180 square meters. Featuring 3.0-meter ceilings, the standard leased floors will have a spacious feel, and the strong earthquake resistance (vibration damping), security functions, and design sense will contribute to the building grade.
We are moving forward with the work with a target completion of the spring of 2010.
Features
- 400-square-meter roof garden sharing greenery with adjacent Hie Shrine.
- High-range specs, earthquake resistance, and strong security.
- Business hub: Highly convenient access with six converging subway lines.
- Facade combining design sense and reduced energy consumption.

The top of the building will feature a roof garden with various greenery. In concert with the deep forest of adjacent Hie Shrine, the roof garden will provide a refreshing space for office workers while also contributing to a reduction of the heat-island effect in the city center.
The 3.0-meter ceilings on standard leased floors create a spacious feel, and, with 5.0-meter ceilings, the first-floor space is suitable for showroom use. Despite its relatively modest size, the building features a vibration damping structure, and there are three levels of security (building entrance, elevator car, office door).
This building is located in the Akasaka-Nagatacho area, a business hub. It is an extremely convenient area, with six subway lines converging in the vicinity (Tokyo Metro Namboku, Chiyoda, Marunouchi, Ginza, Hanzomon, and Yurakucho lines), and the Tokyo Metro Tameike-Sanno and Kokkaigijidomae stations are only a two-minute walk away.
Facade combining design sense and reduced energy consumption
The east and west facades consist of vertical louvers limiting the effects of the sun's rays. For a sophisticated design worthy of the building's Nagatacho location, the facades create a series of vertical lines while preserving the view. Since the air conditioning burden is highest on the east and west sides, the use of sun-blocking louvers there also serves to increase the building's energy efficiency.
