Dentsu's head office rose in Shiodome in 2002 after a competition won by Ateliers Jean Nouvel. Besides offices it holds halls and studios, the Advertising Museum Tokyo and the Dentsu Shiki Theatre SEA.

Office history: from a 12-foot rented house to a 48-floor tower
- 1901 A small rented house
Hoshio Mitsunaga started an advertising agency, Nippon Kokoku, in July 1901 to fund a news agency, which he set up in the same building that November. The company started out in a rented house only 12 feet wide by 18 feet deep (6 tsubo).
