My wife always has bad allergy problems when she visits Japan, especially at this time of year, but she puts up with it because she doesn’t want to wear a mask. The Japanese however don’t care how silly they look as long as their face mask protects them from germs and allergy causing stuff.
The latest in high-tech Japanese face masks is this USB cooled one with a built-in fan. Just plug it into your laptop USB port and enjoy cool fresh air blasting into your nose and mouth at 1500rpm.
All that high tech and it only costs 2480 Yen (about $24).
