The Beginner’s Guide to Japanese Internet Slang: WKTK, KWSK and More

It should come as no surprise that Japan has its own unique internet slang. You can call me a Grade-A , ネット中毒 (ねっとちゅうどうく- internet addict). I spend more time than I’d like to admit roaming the internet, ghosting my favorite blogs and watching hours worth of tear-jerking Japanese dramas and cat videos on YouTube.

During my hours of internet lurking on Japanese forums and social networks, I’ve picked up a few ネットスラング (ねっとすらんぐ internet slang) that I’d like to share with you.

Below, I’ll show you some of the most common Japanese internet slang that’s dominated Japan’s web!


Top Four Japanese Internet Slang

Whether you’re posting updates on Mixi or streaming your favorite anime on Nico Nico, these four internet phrases will show up everywhere:

W – Lol

“W” is the equivalent to “lol.” The “w” is short for 笑う (わらう – to laugh). You’ll also see the kanji character 笑 (わらい laugh) used pretty often. I find that 笑 is more mature sounding (think of “hahaha” vs. “lololol”), and in my experience I’ve seen more guys use 笑 over “w”.

WKTK – Excited

This is such a popular acronym that it’s spread from the web and is now found in text messages, advertisements and even modern manga. Try sounding it out and seeing if you can guess what it means first.

Did you get it? Wktk means that you’re excited for something to happen. It comes from ワクワクテカテカ (わくわくてかてか) which is a Japanese onomatopoeia for “excited” or “trembling with excitement”.

Excited for the second season of your favorite anime to come out? Wktk.

Your bff Jill is about to text you about those AKB48 tickets she scored? Wktk.

You’re watching the microwave count down the seconds until you can be united with your reheated okonomiyaki? Wktk.

KWSK – Details, please

Kwsk is another acronym using the Latin alphabet (Spoiler alert: There are a ton of those). Kwsk is short for 詳しく (くわしく- in detail). The real meaning of kwks is “Give lots of detail(s), please!” or better known, “Details, please.”

You’ll find this on all corners of the internet. Another way to be polite in Japanese when asking (begging) for something is by using 4649 (also written as “yr” and “46”). The number four stands for よ, six is ろ, 4 is し and 9 is く. Together these numbers stand for よろしく (please [requesting]).

乙 – Good work

Okay, I know what you’re thinking: what’s that? This Japanese kanji character is pronounced as おつ in this situation, and has a heavy presence on the Japanese side of the internet. 乙 is an abbreviation of お疲れ様 (おつかれさま), a phrase meaning “Thank you for all your hard work”.

You’ll see this on a number of forums and video streaming websites, and may even get it in a text from time to time. Similarly, you might see someone get praised with うぽつ (thank you for uploading) or 888 (pronounced as ぱちぱちぱち, the sound of snapping or clapping), which means “clap clap clap.”

Japanese Slang for Online Social Networks

Finally, you’ll need to know how to talk about who you’re following on Twitter or which fan group you’ve just joined. If you’re an internet socialite then think of these as your survival phrases for the internet realm.

ツイ- A tweet

Written in both hiragana and katakana, つい/ツイ (a tweet) is the noun form of “tweet.” If you’re a ツイッター中毒 (ついったーちゅうどく – twitter addict) then you’ll be sending out tweets just as fast as your feed is updating them. The verb “to tweet” is つぶやく (literally “to murmur”).

Some people use ツイート(する)(ついーと[する] – to tweet). When someone is retweeting or specifically directing a tweet at someone, リツイートする (りついーとする – to retweet) is used.

フォロー – To follow

This is an easy one! フォローする (ふぉろーする) is “to follow” an account on social media sites like Twitter or Instagram. If you do follow your favorite celebrity (Hiroshi Abe♥), then you’re known as their フォロワー (ふぉろわー – follower).

クラスタ- Fan group

クラスタ (くらすた cluster) is another way to say “fan group”. If you love Ayumi Hamasaki, then you could be part of a あゆクラスタ (あゆくらすた – Ayu fan group).

Or if you’re a person who likes to tweet or reblog meaningful quotes, you could say you’re part of a ネタクラスタ (ねたくらすた – a group who tweets something amusing or interesting). Where can I join the ケーキクラスタ (けーきくらすた cake cluster)?

GGRKS – Google it yourself

This is short for ググレカス (ぐぐれかす- google it, scum). It’s used to say “Go Google it yourself” when someone is too lazy to look up information. Since “scum” is a part of this acronym, it shouldn’t be used left and right. Still, you’ll see ggrks all over 2ちゃん (にちゃん).

誰得 – Who benefits from this

I had seen my friend’s Twitter and Facebook feeds painted with the expression 誰得 (だれとく) but no matter how many dictionaries I searched through, I just couldn’t grasp its meaning. 誰得 is an abbreviation of 誰が得するんだよ (だれが とくするんだよ). Both expressions can be translated to: “Who benefits from this?” It’s best used when someone is getting irritated about something:

My boss asked me to work overtime, but there’s nothing to do. 誰得?

Here’s an article about a five-hundred dollar macaroon that’s encrusted in 24k gold! 誰得?

Sometimes you’ll see others respond to 誰得 with 俺得 (おれとく) which is like saying, “It’s for me!” or “It’s for my benefit.”

Online Gaming Japanese Slang

You don’t have to be a big gamer to use these next four. In fact, some of these slang words will still be seen around forums and chat rooms.

55 – Go go!

Since the Japanese number five is pronounced as “ご,” it’s pretty easy to guess the meaning of “55!” when it’s used on the web—especially if you’re about to embark on an online battle with your gaming partners.

Right before a game starts, or when you’re about to take down the final boss you’ll see 555 (ゴー、ゴー、ゴー!- go, go, go!) written in the chat (if your partner’s not already shouting into your headphones!).

おめ – Congrats

おめ is an abbreviation of おめでとう (congratulations). Think of it as saying “congrats.” I first ran into this after finishing a virtual game of 七並べ (しちならべ – Sevens card game), and ever since have spotted it anywhere congratulations are due (in the virtual world).

Player 1: プレーヤー2、おめ (ぷれーやー2、おめ – Player 2, congrats.)
Player 3: 2さん、おめ (2 san, congrats.)
Player 2: あり ^^ (Thanks.)

あり – Thanks

If you looked at the example above, you may have noticed that Player 2 says “あり” after being congratulated by fellow players. あり stands for ありがとう (thank you). In my experience on the web, this is used mostly in games as a short “thanks,” but you may still spot it on message boards.

こn – Hi

A common and quick greeting, こn (こん) is short for こんにちは (hello). It’s used when greeting others in web chats and live-streaming comments, or when greeting someone in a conversation. This pattern of kana character + Latin character is pretty common and can be seen with other ネットスラング like んp (no problem) and うp (upload).

Japanese Online Personalities and Personas

No matter where you are in the world, there will always be internet trolls or annoying anons gracing message boards. Here’s a list of some common internet personalities that you’ll run into.

名無しさん – Anon

If you’re familiar with 2ちゃん (にちゃん – the name of a Japanese textboard), then you’re no stranger to 名無しさん (ななしさん – anonymous user). Don’t confuse 名無しさん for a ROM (ろむ- read-only member), a person who reads website content, but doesn’t make any comments or posts.

ズッ友 – Bff

Have you ever been on Facebook or Instagram and seen a #bff or #friends4life tag or sticker? ズッ友 (ずっとも) is the same. ズッ友 is a combination of ずっと (forever) and 友達 (ともだち – friend), making it equivalent to (best) friends forever. A lot of girls use this in photos when tagging their friends. It’s used frequently on social networking sites like Twitter as well.

オワコン – Out-of-date contents

オワコン (おわこん) means “out-of-date.” It can refer to a trend (like an internet meme) that’s no longer popular, or a person/celebrity who’s dropped off the radar. オワコン originally came from 終わったコンテンツ (おわった こんてんつ – out-of-date contents).

If a dance parody is no longer popping up everywhere on YouTube or if everyone’s heartthrob is no longer appearing in movies, then they’re probably オワコン.

KY – A person who can’t read the mood

KY is an abbreviation of 空気読めない (くうき よめない), which means someone who can’t read the air or mood. Maybe someone keeps sending you ジュリエットメール (じゅりえっと めーる – love e-mail from a female) or ロミオメール (ろみおめーる – love e-mail from a male) even though you text back “k” or “not interested.”

In that case, that someone is a KYな人 (KY なひと – a person who is KY). This phrase has spread from the internet; you may see it in manga or it may even pop up in a few texts.

ニコ厨 – Nico Nico addict

The video streaming website, Nico Nico (ニコニコ,  にこにこ) is YouTube’s cousin from overseas. What makes it either fantastically clever or unbearably annoying is that user comments are overlaid directly on top of a video, rather than below the video.

A ニコ厨 (にこちゅう) is a person who’s addicted to Nico Nico, or a “Nico Nico addict.” The word 厨 (ちゅう) comes from 中毒者 (ちゅうどくしゃ – addict or junkie). When used alone, 厨 (ちゅう) can mean, “someone who makes childish posts on online message boards.” I’ve seen it combined with a few other words like ゲーム厨 (げーむ ちゅう; gaming addict).
