Dentsu Japan Headquarter

Text and image from wikipedia.

Dentsu's sales are more than double its nearest competitor, Hakuhodo or ADK, in the Japanese market, thanks to the company's origins as a media representative during the early part of the 20th century, producing the first newspaper advertisements as well as the first television commercials in Japan. The company now offers a range of services, from traditional and creative marketing to specialty disciplines such as sports marketing, investing in feature film production and acquiring broadcasting rights, PR, digital contents, and a growing range of communications services.
