Japanese Internet Slang: A Glossary

Japanese online comments are dense with slang, and a single word can flip a sentence from sincere to sarcastic. This glossary explains the terms you'll run into most in our translations. Some are jokes, some are labels people throw at each other — where a word is derogatory, we say so plainly rather than endorse it.

Laughing and hype

The Japanese internet has a whole vocabulary just for laughing.

w / ｗｗｗ
The literal "lol." It comes from 笑い (warai, laughter) — one w is a chuckle, a long row of wwww is howling. This is the seed everything below grew from.
草 (kusa)
"lol / lmao." Literally "grass": a row of wwww looks like blades of grass sprouting, so 草 came to mean laughter itself. "That's grass" = "that's hilarious."
大草原 (daisōgen)
"A vast grassland" — when 草 (a patch of grass) isn't enough. Reserved for something wildly funny. You'll also see 草不可避 ("grass unavoidable").
ｷﾀ━━━(ﾟ∀ﾟ)━━━!! (kita)
"It's HEEERE!" A classic 2ch/5ch-era ASCII-art shout of excitement when something long-awaited finally happens. The face and the ━ dashes are part of it.
神 (kami)
"God / godlike" = amazing. 神回 (kamikai) is a "god episode"; 神対応 is a "godlike response" (someone handling a situation perfectly).

People and labels

How posters refer to themselves and each other. Several of these are pejorative — noted where so.

名無し (nanashi)
"No-name." The default anonymous handle on 5ch (名無しさん, "Mr. Nobody"). Being nameless is the norm; using a fixed handle (コテハン, kotehan) stands out and is often mocked.
ネトウヨ (netouyo)
From ネット右翼, "net right-winger." A loaded label for online nationalist / hard-right posters, usually thrown by their opponents.
パヨク (payoku)
A derogatory label for the online left, used mainly by the right. It spread from a 2015 online spat (the "payo-payo-chīn" meme) rather than being a neat mirror of ネトウヨ — but in practice the two get slung across the same divide. Both are insults.
陰キャ / 陽キャ (inkya / yōkya)
"Gloomy character" vs "sunny character" — introverted/awkward vs outgoing/sociable personality types. Often self-deprecating (people call themselves 陰キャ).
リア充 (riajū)
Someone whose "real life is fulfilling" — a partner, friends, a social life away from the screen. Half-envious, half-mocking, from the online/otaku point of view.
DQN (dokyun)
A delinquent, trashy, or obnoxious person. Pejorative; read "dokyun." Originally from a TV show name.
情弱 (jōjaku)
"Information-weak." Someone seen as uninformed, media-illiterate, or easily fooled — a common jab in news and political threads at people who supposedly missed the real story.

Threads and board moves

Vocabulary specific to how anonymous boards work.

>>1 (the OP)
">>1" (read ">>ichi") is the first post in a thread — i.e., the person who started it. "乙 >>1" thanks them for making the thread.
乙 (otsu)
"Nice work / thanks / cheers." Short for お疲れさま (otsukaresama). Often aimed at >>1 for starting a thread — though it can be sarcastic ("nice try").
釣り (tsuri)
"Fishing" = bait / trolling: a post written to provoke reactions. 釣られた ("I got fished") means "I fell for the bait."
煽り (aori)
"Fanning the flames." Provocation — needling or baiting others to spark a reaction or a fight. An 煽り comment is written to get a rise, not to make a point.
荒らし (arashi)
A troll or vandal who disrupts a thread with spam or flames. Distinct from 釣り (bait): 荒らし is about wrecking, not tricking.
炎上 (enjō)
"Going up in flames" — a pile-on or public backlash against a person, brand, or post.
特定 (tokutei)
"Identification." Crowd-sourced sleuthing to identify a person, place, or account from clues in a post. It shades into doxxing once it exposes private information.
凸 (totsu)
"Charging in" (from 突撃, totsugeki). Descending directly on a target — a call, a visit, a comment raid, a direct message — not always a complaint, and not only after a 炎上.

Feelings and fandom

Words for how people feel about things — heavily used in fan communities.

推し (oshi)
Your "pick" — the idol, character, or creator you support and root for. 推し活 (oshikatsu) is the fan activity of supporting them.
尊い (tōtoi)
"Precious / sacred." A fandom word for something so good it feels almost holy — a pairing, a moment, a performance.
エモい (emoi)
From English "emotional." A nostalgic, bittersweet, moving feeling — the Japanese internet's version of "that hits different."
ワロタ / ワロス (warota / warosu)
"Lol'd" — past tense of laughing (a Kansai-flavored わろた). An older cousin of 草.

ID Photos for 20 Yen and F-35 Parts via Hong Kong

Two stories ran together: images of Japanese driver's licenses and other IDs reportedly traded on a Chinese-language dark-web site for roughly 20 yen each, and F-35 stealth-canopy parts reportedly routed through Hong Kong to China during shipment from Australia. Japanese netizens voiced helplessness at leaks individuals cannot prevent and questioned the logistics and oversight behind both.

France's High-School Protests Swell to 250,000 as Clashes Bring 490 Arrests

France's high-school protests over school conditions entered a third week and escalated on October 6, when roughly 250,000 people joined nationwide, left-wing groups merged in, and clashes with police led to about 490 arrests. The crowds included teachers, parents, and unions, and much of the movement stayed peaceful. Japanese netizens split between exasperation at the destruction, ribbing of France's protest culture, and envy of its politically engaged youth.

Why Tourists Asking Directions in English Rubs Some in Japan the Wrong Way

A viral post about tourists asking for directions in English — and stopping the listener from using a translation app — spread alongside a claim that guidebooks promise 'Japanese people will try to speak English.' The claims rest on individual posts and secondhand anecdotes. Many netizens bristled at a perceived lack of respect, while others said visitors simply expect English in a developed country, or dismissed the story as thin, discrimination-baiting rumor.

Hackers Brand Japan One of the World's Worst for Cybersecurity

The ransomware group Qilin, blamed for the 2025 Asahi cyberattack, called Japan one of the world's worst countries for computer security after one of its alleged members was arrested in Osaka. The remark landed amid a run of domestic data leaks. Most Japanese netizens accepted it with self-criticism about corporate cost-cutting, while others mocked the government's digitization push or dismissed the jab as attacker bluster.

Japanese Culture Festival in Istanbul Attacked

A Japanese anime and culture festival in Istanbul was attacked by a group chanting religious slogans, cutting the event short, with families and children among those present. In Japan the news clashed with Turkey's long-held image as a pro-Japan country and set off debate over whether Islamic religious rules and anime culture can coexist. Much of the reaction generalized from the attackers to Muslims broadly and tied the story to immigration at home, while a smaller group pushed back against that leap. Reports confirm the attack and the damage, but the claim that children and families were specifically assaulted is not independently verified.

France's Student Protests Enter a Third Week

France's high-school protests over public-school conditions entered a third week with escalating violence, including a 15-year-old who lost a hand to a police-fired munition, and reportedly reached wealthier parts of Paris. Japanese users mostly measured the unrest against their own near-absent protest culture, mixing envy and scorn, while arguing over whether the cause was schools, a revolt habit, or immigration. Reporting ties the injury to a police stun grenade and the underlying trigger to school conditions rather than the immigration frame some assumed. A sharp class reading — elite students demanding free tuition while low-paid elders direct traffic — ran through the thread.
