A bomb threat has been made against the headquarters of Dentsu Inc. in Tokyo, the advertising agency said Friday, with police cordoning off the building and commercial facilities in the vicinity.

The threat was made as a posting with a personal name on the company's website on Friday morning, an informed source said. The message also said that "a bad company that disturbs the world will be disciplined," the source said.

Dentsu is based in the Shiodome business and leisure district near Tokyo Bay, marked by office towers, shopping centers, and high-rise hotels.

Companies including Shiseido Co., ANA Holdings Inc., Nippon Television Network Corp. and Kyodo News have their headquarters in the area.
