The Tokyo Setagaya-ku Cleaning and Recycling department uses expired departmental flyers for its business cards. The department uses the reverse side of printed material that has been used in the department. The front of the business card contains the usual business card information. On the back of the cards Lets Japan received is a portion of an announcement about the trash collection schedule at the end of the year. The flyer paper is not as heavy as a standard business card, but heavier than a standard piece of paper.
When two employees of the Cleaning and Recycling department presented their business cards to LJ, the employees pointed out the reverse side of their cards.
