The word "hentai" does not have the same meaning in the West as it does in Japan. If in the West the sexual connotation is clear, it is not the same in Japan. Hentai in Japanese means weird or bizarre and does not refer to porn as we usually imagine. The Japanese have another term for what is pornographic in general: "ecchi". In the West the use of the term "hentai" has been derived to refer to actual Japanese pornographic manga.
Hentai is known for its exaggeration of male (penis size, for example) or female (large breasts, etc.) attributes and its exploration of taboo subjects. It is a haven for fantasies and fetishes. This explains why there are many subcategories in hentai (sadomasochism, incest, etc.). Among these categories, the one we are interested in is mizugi or sukumizu.

What is mizugi?
Mizugi or sukumizu is a subcategory of hentai that can be classified as fetishism. Sukumizu is a contraction of school mizugi. It refers to a navy blue swimsuit that is usually a one-piece, but can be a two-piece. Sukumizu can be worn by boys or girls. To speak of mizugi for a swimsuit worn by an adult may be considered an insult. In hentai, it refers to a category of pornographic manga that caters to (Japanese) swimsuit fetishists. In these pornographic vignettes, the mizugi is presented in such a way as to highlight the advantageous shape of the girl wearing it, especially her large breasts. It is an exaggeration and a fantasy.

The Japanese fantasy behind the mizugi
Seen from a Westerner's point of view, it may seem strange that a swimsuit as sexy as an Eskimo coat could be worth so much fantasy. This is to forget that the Japanese don't like bikinis, which they consider too vulgar. Although these swimsuits on a European woman's body are not sexy, legend has it that the mizugi worn by a pretty Japanese woman can turn any man's head, especially when wet, that's how Japanese males like it.

However, behind this fetish lies the schoolgirl fantasy. It must be said that in Japan, almost all schools have swimming pools. Thus, most of the hentai mizugi scenes take place in these pools. Hentai mizugi is a world of schoolgirl fantasies in which a gym teacher with sexual immoderation has no qualms about seducing and penetrating his young students, always looking innocent and, if necessary, wearing glasses.

Mizugi and water
As you can see, almost all mizugi scenes take place in an aquatic environment. The water in the mizugi is not simply water. It is sublimated in the drawings to the point of becoming erotic. Seeing it flow over this swimsuit reminds us of the bodily fluids resulting from sexual intercourse. The water, moreover, enhances the shapes of these sukumizu-clad bodies.

Example of hentai sukumizu scenarios
One of the most famous hentai sukumizu is Mizugi Kanojo. Mizugi Kanojo is a series that tells, in each episode, the escapades of couples with always the Japanese swimsuit as the central theme. One of the episodes stars Mizuho-chan, a girl with big breasts, and Hiro-kun, her well-built boyfriend. One day, Hiro suggests to Mizuho that she take up swimming to keep in shape. He even offers to train her after work at the pool where he is a lifeguard, as he has a lot to learn about swimming. Mizuho dutifully accepts. What she doesn't know is that her new sport will turn out to be more exciting than expected. Meanwhile, Takuya finds himself in a compromising situation with his pretty neighbor.

Another episode tells the story of girls who have nothing in common except their passion for swimsuits. They discover that they have a connection that goes back a long time. The ancestor of one of them was a female ninja whose specialty was sexual combat. This means that she defeats her enemies by draining all their sexual energy. One day the spirit of this ancestor will awaken in her and it will be her boyfriend who pays the price.
