In Western-made works, Asian characters, especially those who are otherwise unassuming Funny Foreigners, are likely to know some kind of martial arts and demonstrate it proficiently, if not superlatively. For instance, the stereotypical Japanese character in many Western works written in the first half of the 20th century will probably demonstrate his jujitsu skills on some other character at some point.
See also Everybody Was Kung-Fu Fighting. All Chinese People Know Kung-Fu is a similar trope, but is about how Japanese (one Asian group) view Chinese (another Asian group). All Monks Know Kung-Fu is this trope applied to all kinds of monks. Can lead to a Chop Sockey.

- During the 1970's kung-fu craze, it was established that Fin Fang Foom knows giant monster-sized kung-fu that he can use against other giant monsters. Because he's a Chinese dragon, you see. Or at least, an alien dragon that hung out in China.

- Weiss starts off as a Politically Incorrect Hero in White Noise. The first thing she says when her father tells her that Yang is her bodyguard is that "because she's Asian, and probably knows some kind of kung fu, I'm supposed to believe that she'll be able to keep me safe over your other guards?". Yang doesn't know martial arts, but she can still fight.

- In the original The Karate Kid series, every single Japanese character knows karate - namely, the men. The women, on the other hand...

- In Judge Dredd, the film's Asian Evil Genius, played by Joan Chen, busts out martial arts during the climax's Designated Girl Fight, even though there was no prior mention that she was capable in combat.
- In Anna and the King, the King is shown doing tai chi. This is completely contrary to history note and was put in to appeal to fans of Chow Yun Fat and of this trope. Even the movie poster has a martial arts background.
- Averted in The Green Hornet Serials. With one exception (a karate chop), Kato uses the same Hollywood fighting style that everyone else is using.
- Ironically, the actor playing Kato in the original series was specifically chosen for his martial arts prowess. His name? Bruce Lee.
- The Dead Pool plays with this trope. Dirty Harry gets a new partner. An asian one. He assumes his new partner knows martial arts, the partner points that it's kinda racist to assume this. Some ten minutes later, said partner disarms and knocks out a robber with some fancy martial arts moves.

- For the first three seasons of Star Trek: Enterprise, Hoshi Sato is the least confident member of the crew, but in an effort to make her more of an Action Girl she's retconned with martial arts skills which she uses against Phlox's kidnappers in Season 4. While it's quite likely Hoshi would have become more assertive after her experiences during the Xindi conflict, it would have made more sense for Hoshi to have used the more simple takedowns taught to the crew by Major Hayes during this time. But less cool, we're sure.
- In an episode of Lovejoy, a Japanese customer helps Lovejoy escape some thugs by pretending to know martial arts. They believe this trope and run.

T.J.: Where'd you learn to do that?Cassie: My ancestors invented it.

- In an episode of The Invisible Man, Hobbes has to work with his Chinese counterpart. Given Hobbes's personality, he soon comes to verbal blows with the Chinese agent and offers to settle it with martial arts. The Chinese agent claims that Hobbes believes this trope. However, the guy in question is a spy. It's kinda assumed that someone like that would be trained in hand-to-hand combat.
- Averted and played for laughs in MADtv's "Average Asian" sketches where a common joke is that everyone believes the eponymous character has martial arts abilities despite him constantly telling everyone that he doesn't. He can call upon ninjas, though.

- An The O'Reilly Factor man-on-the-street segment filmed in New York's Chinatown and aired in October 2016 set off controversy for its use of pretty much every Asian stereotype imaginable; at one point the interviewer asks an Asian man if he knows karate: https://www.youtube.com/watch?time_continue=134&v=PJmnLzw8NA4
- This trope is an old pro wrestling staple, inherited from the times in which promotions featured foreign heels from exotic lands. If they were Japanese, Chinese or relatively Asian, then they would know some kind of ancient martial art like kung fu or karate, showed in a mystical and sneaky fashion as opposed to the traditional native hero (often because the wrestlers playing the gimmick didn't actually know these arts). Even today, Japanese wrestlers working in American promotions are practically forced to use a stereotypical puroresu/strong-style moveset with plenty of kicks and artful holds.
- Billy, the "Jap butler" in The Bat, practices jujitsu on Richard Beresford in an attempt to prevent him from entering.
- In Earthbound, Poo is the only Asian party member, and he actually gets a disadvantage to his attacks when he's equipped with weapons apart from his Infinity +1 Sword. However, from what we see of his home country, it's more akin to India than China or Japan.
- Averted in The Matrix: Path of Neo as the only ones who know martial arts are either trained practitioners or gangsters.
- Exploited in Freddie Wong's Kung Fooled. First he scares off a would-be mugger by imitating kung-fu, then he gets into a "duel" with another Asian guy who is also pretending to know kung-fu. They proceed to make themselves look utterly ridiculous.

- Something*Positive mocks this. Peejee rescues a man she knows from an awful date by pretending he's her boyfriend, and angrily scaring off his date by threatening her with "the ancient Chinese secret of the bowel-emptying death-grip dragon noogie".
Peejee: Fucking white people. It amazes me the bullshit they'll believe as long as you're Asian and precede everything you're saying with "ancient Chinese secret". Eyes so big, brain so small.
- Doctor Sun of Girl Genius. Frankly, it wouldn't be true to its pulp roots if he didn't.
- This trope is discussed by Ashley in El Goonish Shive. She states that she has had people assume she is "some kind of magical martial artist" simply because she's Asian. Amusingly, the character she's talking to is actually some kind of magical martial artist. The author also took the opportunity to gently mock himself over the fact that Nanase, the first explicitly Asian character he introduced was a martial artist (Tedd was introduced earlier, but the fact that he's half-Japanese wasn't made known until later).
- Futurama likes to mock this trope. In one episode about Star Trek, Asian-American George Takei complains that people should not expect him to know karate just because of his Asian ancestry. It turns out that he does (which is true in Real Life) but that they shouldn't have assumed that he could.
Takei: When have I ever led you to believe I have studied karate?
Shatner: Well, you never talk about yourself!
Takei: If you'd shown a little interest...

Additionally, many high schools in Japan have clubs for kendo (fencing), kyudo (archery), naginatajutsu (halberd/spear), Karate and Judo; these clubs are more like sports teams than clubs though.
- Same with the Philippines and arnis/kali, though this is mandatory. Some schools specialize in fencing, karate, judo and Taekwondo.
- Korea has similar clubs of kenpo and taekwondo, among other martial arts. It should also be noted that young men must enlist in the military which means a significant number of citizens have received combat training.
- Taiwan and Singapore also practice nation-wide compulsary military conscription. Its not unusual then that every male citizen has had *some* hand-to-hand combat training, formal or otherwise.
- The first time an Asian-American woman (Caroline Hsu) was elected Rose Queen, for the 2002 Tournament of Roses parade, all the commentators made sure to mention that she was a taekwondo black belt.
