What Are Japanese School Swimsuits? The Fetish of “Sukumizu” in Anime

in Your Friend in Japan

One thing we love a lot is anime episodes with Japanese school swimsuits, which are always pleasing to the eye. Let’s examine the history of Japan’s “school mizugi” (aka sukumizu) as seen through anime, and also study the history of actual school swimsuits in Japan!

It’s a very special time for us at J-List, because 30 years ago this week, we started the first anime and hentai shop selling to fans around the world. And we’ve been able to make it this far thanks to our wonderful customers. We’re celebrating with a huge 20% sale on all in-stock Japan products, through October 7th. Start browsing now!

What Is a Sukumizu? (Explaining Japanese School Swimsuits)

Sukumizu is short for スクール水着 (sukūru mizugi), the official “school swimsuit” that students in Japan wear in swimming class at school. For girls, it’s a tight, dark navy one-piece, usually with a name tag sewn on the chest, and everyone in Japan must wear them during swimming class. That’s why it became such a fixture in anime: everyone in Japan has worn one, and has a close connection to them. (And every boy has probably had a crush on a girl wearing one.)

What is the history of Japan’s Sukumizu?

In the years after WWII ended, Japan was rebuilding its ruined country. It was common for children to take school trips to different parts of the country. On May 11, 1955, the ferry Shiun Maru, carrying students on a school trip across the Seto Inland Sea, collided with a freighter in thick fog and sank within minutes. 168 people died, around 100 of them students. Very few of them had been able to swim.

The disaster shook the country and made swimming safety a core issue for educators. Schools began building pools, a push that increased as the 1964 Tokyo Olympics approached. Before long, swimming had become a core curriculum for all students in Japan. And since Japan loves to put their children in uniforms, the “school swimsuit” was born.

Why Did School Swimsuits Change?

The original school swimsuits, now called old-style sukumizu (旧スク水), had a unique design with a line across the crotch and a place for the student to write their name and class number, as in the clip above.

“Old type” school swimsuits give way to modern ones

As the design evolved — and, to be honest, the swimsuits started becoming sexualized in anime and hentai games — the design was modernized. Today, school swimsuits are more like the clip above, lacking some of the features that made them so unique. Sadly, the classic school swimsuit design is now mostly something you see only in otaku circles.

The 8 Best School Swimsuits Seen in Anime

Let’s look at 8 of the best sexy school swimsuits appearing in anime!

Yoshika Miyafuji’s swimsuit got fans’ attention

Yoshika Miyafuji Was Defined by Her Sukumizu

In Strike Witches (it’s an anime about WWII, honest!), Yoshika has a tight-fitting school swimsuit on under her sailor uniform. Of course, the camera moves in for a close-up quite often.

This classic school swimsuit design is perfect for fan service moments, and anime like To Love-ru Darkness made great use of the swimsuit’s body-hugging features.

School swimsuits represent the ultimate image of youth gone by

School Swimsuits Represent Youth

A school swimsuit represents youth and innocence and is often associated with young-looking “loli” characters. A joke we often see is, “A high school girl is still so flat-chested she can still fit into her school swimsuit from the sixth grade of elementary school.”

Swimsuit scenes also serve as fan service

You don’t think of Kaguya-sama as a fan-service show, but they put a bonus episode on one of the Blu-rays to thank fans for faithfully buying all the discs.

School Swimsuits as Fetishism

Several anime series draw heavily on the fetishization of the classic school swimsuit. This is Softenni! the Animation, an anime about soft tennis, as you can see.

Sukumizu Are a Staple of Hentai, Naturally

It’s common to see characters wearing school swimsuits in hentai anime, like the Eroge! hentai anime. It’s great to see a guy having sex with a girl wearing one of these sexy swimsuits.

Wish Fulfillment with School Swimsuits?

What would you do if you had the power to stop time? Would you have some fun with girls wearing these swimsuits? That’s the premise of the Gakuen de Jikan yo Tomare! hentai anime.
