The museum, located in Caretta Shiodome B1 & 2F (connected to the Dentsu Building), occupies two full floors, demonstrating Japanese advertising from its historical beginnings to present day. The museum is divided into two main parts: the exhibitions and a library.

The exhibition area demonstrates the development of Japanese advertisements from the Edo Period (1603-1868) to now, exhibiting different forms of advertising, from paper signs, postcards and posters to newspapers and television ads. It also shows how the culture and trends in Japan have changed over the years, as shaped by advertisements. Besides the permanent exhibits, the museum also has temporary galleries featuring commercials that were awarded the annual Kokoku Dentsu Award.

The library is located in B1F and it has all the books you can think of on advertising! The collection holds over 12,000 Japanese books and 2,700 foreign books with no cost to read any of them—just note that you can't take them out of the library.
