Incest in Japan – Why Does It Look Acceptable?


You may have noticed in today’s anime, novels, and manga the amount of incestuous content in the stories. Not only in erotic works, but also in children’s and youth works you always find a passion or fetish for younger sisters.

Why does Japan allow such anime? How did this genre become popular? How does Japan really view incest? We will answer these questions through this article.

Although Japan is very traditional, it is quite open when it comes to sexuality, probably due to the absence of Christian religions in the country. Even in the Shinto religion the Japanese believe it was an incestuous relationship that gave rise to the country.

In feudal Japan the lack of freedom made the family grow incestuously. Clans traditionally encouraged cousin relationships to perpetuate family dynasties. If a father were widowed, he would usually marry his daughter.

How does Japan view incest?

It was only with the westernization of Japan that the practice of incest was prohibited in the country. Genetic science researchers have found that incest causes several problems in human DNA.

A law against incest was created, but it was abolished in 1881, giving freedom to consensual incest. However, the Civil Code of Japan does not allow marriage between family members. Socially incest in Japan is strongly stigmatized.

After globalization, this kind of relationship became unusual. This topic is not usually addressed in Japan. The Japanese have no opinion on the subject, they regard it as a shameful act and deny anything about it. As much as the Japanese say that incest does not exist, it happens in secret from Japan and the world.

Some reports say that even mothers were having sex with their teenage children as a result of their husband’s absence at home. Some mothers claim that this kept their children focused on studies and not girls.

As much as some see sex as pleasure, having relationships with relatives can end up affecting emotionally and changing the way we view our relatives.

Just don’t take it literally, nor generalize, it’s a case among millions. Such cases also happen in all countries. Worst of all is when these things happen without consent.

Why is incest successful in anime?

The first incest anime / hentai (involving sex) was released in the 1980s under the name Cream Lemon, which focused on the brothers Hiroshi and Ami.

There are currently several hentais involving incest from sisters, mothers, and others. Even TV anime often pull aside incest with works involving younger sisters like oreimo and Imouto sae Ireba Ii.

In anime the younger sisters end up acting in an indecent manner. Do the younger sisters really behave like anime? In Japan, older brothers are greatly admired and sought after by their younger sisters.

Many older brothers strive to care for their younger sisters. It would not be abnormal if it ends up resulting in a passion or love relationship.

The target audience for these incest animated works is usually antisocial and lonely otaku. Probably some of them had a younger sister or had a fantasy with them, so they eventually identify with these works.

Another explanation for the popularity of these anime involving sibling romance is why it is unusual. Unusual and abnormal things get attention and are often more exciting. Companies care little about whether it is right or wrong, their interest is to generate income and profit.

One of the most famous of its kind, I recommend it to everyone, even those who do not like incest, the subject is treated in a very light and comical way. I don’t like the incest genre, but I like this anime, its animation, history and iconic characters.

The anime tells the story of two brothers who do not have a good relationship, but who discover that their younger sister is an otaku addicted to eroge, the relationship of the two approaches. From the synopsis it may sound like something pretty perverted, but the anime is great, funny, innocent and is among my favorites.

How should I view Japan because of incest?

Many people end up creating a prejudice from Japan over incestuous anime. I consider this kind of relationship wrong, but I don’t get involved in criticism and I think each one does what they want. I hate it when people say, “Japan is gross because of incest.”

I think this is hypocritical as several countries like France, Spain, Russia, Turkey, Luxembourg and other European countries allow incest. Even American countries do not forbid family relationships.

Remember that just because otaku like it doesn’t mean the Japanese population approves. Possibly they hate it too. Even if you see incest as wrong because of religion, I find no reason for discrimination. Sexual intercourse itself is disgusting no matter if the person is heterosexual, homosexual or incest.

If it’s consensual, then I don’t care, they face the consequences. We cannot force humanity to follow our concepts of morals. Of course incest in anime is something totally different from real life, I personally see no problem watching anime focused on imouto (younger sisters). Is that you? How do you view all this?
