The NTT Docomo Yoyogi Building (NTTドコモ代々木ビル NTT Docomo Yoyogi Biru?) is a skyscraper located in the Shibuya in Tokyo, Japan. At 240 metres (790 ft) tall, it is the fourth tallest building in Tokyo.


The NTT Docomo Yoyogi Building is owned by the NTT Docomo group. Despite the building's name, it is not the head office for the company, whose headquarters are located in the top floors of the Sannō Park Tower. The building houses some offices, but is mainly used to house technical equipment (switching equipment, etc.) for the company's cellular telephone service.

To commemorate NTT Docomo's 10th anniversary, a 15-metre-diameter clock was put into operation in November 2002. The upper portion of the building also features colored lights that indicates if the weather forecast calls for rain on that day.[1][2]

Solar energy is partially used to power the building. A garbage separation system employed within the office helps to reduce waste and increase the recycling rate. The waste water is recycled for reuse, and rainwater is reused for the building's toilets.[1]

The building does not have any restaurants or other tourist attractions, tourists are not allowed into the building.
