Today’s subject is a Japanese art scroll dedicated to fart warfare.

Yes, you read that correctly. Not chemical warfare. Not psychological warfare. Not even “somebody microwaved fish in the office break room” warfare. We are discussing He-Gassen, a Japanese illustrated scroll whose title is usually translated as “Fart Battle” or “Fart Competition.” It is one of those rare works of art that forces the viewer to ask deep philosophical questions, such as, “How did this survive for centuries?” and “Why did my high school art history teacher not mention this even once?”

What Is He-Gassen?

He-Gassen comes from the Japanese words commonly understood to mean “fart” and “battle” or “competition.” The scroll is associated with Japan’s Edo period, which lasted from 1603 to 1868, a time of samurai, kabuki theater, woodblock prints, strict social hierarchy, and, apparently, people painting other people being blasted across the countryside by weaponized flatulence.

The scroll shows a series of scenes in which men and women bend over, aim with surprising confidence, and unleash shaded gusts of gas at their enemies. Victims tumble backward. Objects are knocked aside. Animals are inconvenienced. At least one assumes the plants had no idea what they had done to deserve this.

It is crude. It is ridiculous. It is also carefully drawn, visually energetic, and unmistakably part of a long tradition of Japanese comic art. In other words, this is not merely a doodle scratched onto the back of a bored monk’s grocery list. This is a full artistic commitment. Someone sat down with ink, paper, and purpose and said, “History must remember this.”

The Edo Period Had Jokes, Too

Modern audiences sometimes make the mistake of assuming that people in the past were constantly solemn. We imagine them walking around in robes, composing poetry, contemplating mortality, and refusing to laugh unless someone made a particularly elegant comment about the moon.

This is nonsense.

People in the past laughed at the same basic things people laugh at today: embarrassment, exaggeration, bodily functions, pompous people being knocked down a peg, and anything involving a cat being surprised by events beyond its control. The technology changes. The architecture changes. The jokes remain stubbornly committed to immaturity.

The Edo period was especially rich in popular visual culture. Woodblock prints, illustrated books, theater programs, cartoons, and satirical images circulated among a growing urban population. Comic and bawdy subjects were not some strange modern corruption imposed by the internet, that vast international archive of bad decisions. They were already there, in ink and paper, long before anyone could blame social media.

Was It Just a Joke, or Was It Political Satire?

The obvious answer is that He-Gassen is funny because farts are funny. This is not a difficult academic conclusion. It does not require a symposium, three footnotes, and an assistant professor blinking slowly over a cup of fair-trade coffee.

Still, some art historians and commentators have suggested that the scroll may also reflect political or social anxieties in Japan during the later Edo period. Japan spent much of the Edo era under the Tokugawa shogunate’s policy of restricted foreign contact. As pressure from Western powers increased in the 19th century, Japanese society faced growing questions about foreign influence, national identity, and the uncomfortable realization that isolation works better when other countries politely agree to stay isolated from you.

Within that context, some have interpreted He-Gassen and similar images as satirical depictions of Japanese resistance to outsiders. In certain related works, foreigners were reportedly shown being blown away by Japanese flatulence. This was not exactly diplomacy as recommended by Emily Post, but satire rarely begins by asking whether everyone is comfortable.

That said, we should be careful not to overinflate the interpretation. Sometimes art is a symbolic response to geopolitical anxiety. Sometimes it is a fart joke. Occasionally, as in this case, it may be both. History is complicated, and occasionally wearing no pants.

Flatulence as Fine Art, Because Humanity Is Consistent

One of the strangest things about He-Gassen is how familiar its humor feels. The images are centuries old, but the basic gag could be understood by a classroom of middle-school boys in approximately 0.8 seconds. Possibly less, if snacks were involved.

This is part of what makes the scroll fascinating. It bridges the gap between refined art history and the universal human instinct to laugh when someone makes a noise they cannot plausibly blame on furniture. It reminds us that historical people were not marble statues with tax records. They were human beings with appetites, grudges, bad jokes, and a willingness to weaponize the obvious.

The artwork is also surprisingly dynamic. The gusts of gas are not subtle little wisps. They are visual shockwaves. They bend the action of the scene. They knock people around like invisible cannon fire. One could almost imagine a military strategist examining the scroll and saying, “Unorthodox, yes, but we must consider all options.”

Fortunately for everyone involved, this does not appear to have become a mainstream military doctrine.

It did, however, become a prominent feature in entertainment, as we discuss in “Professional Farters: The Weird Career Path Your Guidance Counselor Never Mentioned.”

The Divine Wind and the Less-Divine Wind

There is also an irresistible linguistic temptation here. The Japanese word kamikaze is commonly translated as “divine wind,” originally referring to the storms that helped destroy Mongol invasion fleets in the 13th century. Centuries later, the term became associated with the suicide attacks of World War II.

We should tread carefully here, since one term belongs to serious military history and the other belongs to a scroll full of people aggressively mooning their enemies. Still, one cannot help noticing that wind—divine, natural, or suspiciously personal—has enjoyed a surprisingly dramatic role in Japanese historical imagination.

He-Gassen simply takes the concept in a direction no respectable naval historian asked for.

Why He-Gassen Still Matters

It would be easy to dismiss He-Gassen as nothing more than an old dirty joke preserved by accident. That would be a mistake. A very understandable mistake, but a mistake.

The scroll matters because it shows how humor survives across centuries. It shows that satire, popular entertainment, and visual exaggeration were thriving in Edo Japan. It shows that art does not always have to be solemn to be culturally useful. Sometimes art teaches us about politics, identity, class, anxieties about outsiders, popular taste, and the eternal human need to make fun of things that make noises.

It also reminds us that the line between “high culture” and “low humor” is thinner than we like to pretend. Museums are full of masterpieces depicting war, mythology, romance, death, and divine judgment. He-Gassen adds another category: people attacking each other with their backsides. The canon is broader than advertised.

The Final Gust

He-Gassen is one of those artifacts that makes history feel less distant. It collapses the centuries between us and Edo Japan with one magnificently undignified premise: people have always found bodily humor funny.

Yes, the scroll may contain social commentary. Yes, it may reflect anxieties about foreign influence. Yes, it belongs to a broader tradition of comic and satirical art. All of that is worth remembering.

It is also a long illustrated fart battle.

History, ladies and gentlemen, is not always written by the winners. Sometimes it is drawn by anonymous artists who understood that civilization may build temples, write poetry, and organize governments, but sooner or later someone is going to bend over and ruin the meeting.
