In cooler, more temperate countries like Japan, the winter season usually means it’s also flu season. And to combat the disease, Japan’s Ministry of Health, Labor, and Welfare is once again teaming up with Attack on Titan. This latest collaboration will feature posters telling people to cover their mouths. And yes, campaigns like this would make Levi very happy to tell people to keep CLEAN.

The campaign poster reminds people that they must keep their etiquette when staying away from infectious diseases. It tells them to cough or sneeze into their forearms, wear masks, or use a tissue. Furthermore, the campaign also tells people not to use their hands in covering their faces, as this might also spread the disease with the things that they hold.

As part of the campaign, the ministry is also giving out posters and leaflets. They’re also letting people download them online via their official website.
