Free Photocopies on Advertising-Sided Paper

Tadacopy in Japan offers students free photocopying though there is on reason why the business model could not work more broadly. The revenue comes from advertising placed on the reverse side of the paper.

This is a really new business idea. And it’s a new way to make profit. The revenue comes from advertising placed so if we want make business bigger. I think first we should let more and more students come there and use it and make it popular. So that the price of advertising placed will be higher. But I think the costs of this business will be very high. Because photocopies for students are free. How to reduce the costs is another thing we should do. Maybe we can limit the number of students to copy in a day. So if students want to copy they will come earlier and maybe it can make it popular at the same time.
