Ever wonder why most anime characters bleed through the Nose? In today's article we’re going to talk about one of the biggest clichés of all time, Nasal Bleeding or Nasal Hemorrhage called hanaji [鼻血].

In most anime this happens to represent when an anime character feels excited and has perverted thoughts, but how does it happen? Why does it happen? Who created this cliché? We will try to find out in this article.

In most works this happens more with male characters, but it can also happen to females. And it doesn't always mean that the person is aroused or thinking nonsense, simply because something may have caused an impact on their eyes or embarrassment, it is easy to notice that the person doesn't even have time to think and the nose starts to bleed.


Of course, this visual cliché is just a way to demonstrate what the character is feeling and thinking, but there are also some origins and curiosities behind this story.

What is the origin of the bleeding nose cliché?

The nosebleed is like a Japanese superstition, like that if you sneeze 1 time someone is saying something good about you, 2 something bad, 3 you have a cold.

Authors often use this cliché because they find it funny, no other reason in particular, in the same way that all Japanese traits are similar, customs in stories too.

Some claim that the idea is that sexual arousal causes an increase in blood pressure, which in turn triggers a nosebleed. It is even true that blood pressure goes up, but it has nothing to do with nose.


Some believe that this custom came about because in the past professional fighters made small cuts on the forehead to build up tension and atmosphere during a match.

Probably the authors had the same idea of creating this exaggeration and representing that feeling. In other words, there is no story behind this custom of bleeding your nose because of an excitement in anime.
