Every year, Germainゼミstudents visit the advertising museum in Shinbashi. The museum holds a comprehensive collection of Japanese posters and CMs.

Looking at the many advertisements on display, it is possible to discover patterns of change in the way advertising messages were communicated at different times of history. For example, in the Edo period, paper was rare and expensive. As a result, most advertising was done on signs and goods, which were usually expensive, and had to remain local. When paper became more common and cheaper, flyers and posters became the preferred way to advertise. This change led to the production of more adverts, and it became possible for shops and companies to communicate with customers throughout Japan, using newspaper adverts and poster campaigns.
