Japan is a weird country with many weird traditions and days that are really hard for outsiders to understand. おっぱいの日 (Oppai no Hi) is one of those days. Oppai no Hi can be translated to 'Breast Day' in English. It is a made-up holiday created by netizens in Japan and somehow the community loves it and keeps it going every year on November 8.

Actually, it is not that hard to understand why people love it so much because, on this day, all the beautiful girls will show off their breasts on the internet. Many celebrities, actresses, pornstars also join in with the fun of the day, giving everyone a nosebleed.
