Hello, I’m Kodak.
You are studying Japanese when you encounter a sentence like this:
マンションのコンセントが壊れたので、クレームを入れた。
Manshon no konsento ga kowareta node, kurēmu o ireta.
“Mansion,” “consent,” and “claim,” right?
So…someone made a claim because the consent in a mansion broke?
The sentence means:
“I made a complaint because the electrical outlet in my apartment broke.”
マンション ⇒ apartment building / condominium
コンセント ⇒ electrical outlet / socket
クレーム ⇒ complaint
The words look English, but their meanings in Japanese do not match the English words mansion, consent, and claim.
Words like these are often introduced to learners as 和製英語 (wasei-eigo), sometimes called Japanese English or—more casually—“fake English” words.
They are Japanese words that developed from foreign-language material. They follow Japanese pronunciation, grammar, and meaning.
和製英語 (wasei-eigo) literally means “English made in Japan.”
It refers to words or expressions created in Japan by combining, shortening, or changing English elements in ways that are not normally used with the same meaning in English.
Examples include:
サラリーマン — office worker / salaried employee
ペーパードライバー — licensed driver who rarely drives
ハイテンション — highly excited / energetic
バイキング — all-you-can-eat buffet
What Does Wasei-Eigo Mean?
Hiragana: わせいえいご
Romaji: wasei eigo
Literal meaning: English made in Japan
Natural explanation: a Japanese-created word or expression based on English
The expression can be divided into two parts:
made in Japan; Japanese-made
英語 (eigo)
the English language
和製英語
English-like vocabulary made in Japan
Japanese dictionaries define wasei-eigo as expressions that appear to have been borrowed from English but were actually formed in Japan by altering or combining English words.
Many katakana words are ordinary loanwords with meanings close to their source language. Others are shortened, changed, combined in Japan, or borrowed from languages other than English.
Gairaigo vs Wasei-Eigo: What Is the Difference?
外来語 (Gairaigo): Loanwords in General
外来語 (gairaigo) are words borrowed from foreign languages and adapted to Japanese pronunciation and writing.
コーヒー — coffee
カメラ — camera
バス — bus
レストラン — restaurant
These words are not necessarily wasei-eigo. Their Japanese meanings remain relatively close to the source words.
和製英語 (Wasei-Eigo): Japanese-Created English-Looking Words
salary + man
Japanese meaning: salaried office worker
ペーパードライバー
paper + driver
Japanese meaning: someone who has a license but rarely or never drives
フリーサイズ
free + size
Japanese meaning: one size fits most / one size
Foreign-Derived Does Not Always Mean English-Derived
Katakana words may come from German, French, Portuguese, Dutch, Italian, and many other languages.
from German Arbeit
Japanese meaning: part-time job
パン
historically associated with Portuguese pão
Japanese meaning: bread
アンケート
from French enquête
Japanese meaning: questionnaire / survey
It fits the broader topic of Japanese-created and Japanese-adapted foreign words, which is why it is useful to study beside wasei-eigo.

Why “Fake English” Is a Useful—but Imperfect—Label
People search for phrases such as “fake English words in Japanese” because the surprise is easy to understand: a word looks English but does not work the same way in English.
However, fake can create the wrong impression.
The expression may not be understood by English speakers.
What “fake English” gets wrong:
It suggests the Japanese word is invalid, mistaken, or pretending to be English.
A better understanding:
It is valid Japanese vocabulary built from foreign-language material.
How Japanese English Words Are Created
Japanese English-based vocabulary does not develop in only one way. Recognizing the pattern helps you predict why a word differs from English.
Pattern 1: English Words Are Combined in Japan
salary + man
⇒ salaried office worker
ペーパードライバー
paper + driver
⇒ licensed driver who rarely drives
ガードマン
guard + man
⇒ security guard
ベビーカー
baby + car
⇒ baby stroller / pushchair
Pattern 2: A Longer Loanword Is Shortened
コンビニエンスストア
convenience store
パソコン
パーソナルコンピューター
personal computer
リモコン
リモートコントロール
remote control
エアコン
エアーコンディショナー
air conditioner
A shortened form such as コンビニ is Japanese-created and will not normally function as English, but its full source phrase and basic meaning already exist in English.
It is clearer to call it a Japanese abbreviation of an English loan phrase.
See Konbini Meaning in Japanese and Japan’s Convenience Store Culture for a complete beginner-friendly explanation.
Pattern 3: The Original Word Develops a New Japanese Meaning
English source: mansion
Japanese meaning: apartment building / condominium
クレーム
English source: claim
Japanese meaning: complaint
スマート
English source: smart
Traditional Japanese usage: slim, stylish, or elegant
テンション
English source: tension
Informal Japanese meaning: mood, excitement, enthusiasm, or energy level
Pattern 4: An English-Looking Phrase Receives a Japanese Meaning
Japanese meaning: highly excited, energetic, or hyper
Ordinary English high-tension: high voltage, strong strain, or a tense situation
モーニングサービス
Japanese meaning: a discounted or set breakfast service
Natural English: breakfast special
フリーサイズ
Japanese meaning: one size / one size fits most
Not “a size that costs nothing”
Learn why the emotional meaning differs from English in High Tension Meaning in Japanese: Why テンション Means Energy.
Pattern 5: A Brand or Proper Name Becomes a General Word
Original association: Imperial Hotel’s “Imperial Viking” buffet restaurant
Modern Japanese food meaning: buffet / all-you-can-eat buffet
The Imperial Hotel opened the Imperial Viking in 1958 after researching Scandinavian smörgåsbord dining. The restaurant name became associated with the dining style and spread as a general Japanese food word.

Japanese Abbreviations That English Speakers May Not Recognize
Japanese often creates short four-mora forms from longer foreign expressions.
コンビニエンスストア
convenience store
パソコン
パーソナルコンピューター
personal computer
リモコン
リモートコントロール
remote control
エアコン

Why Does Japanese Create So Many Shortened Loanwords?
Long foreign words must fit Japanese sound patterns, so they can become much longer when written in katakana.
コンビニエンスストア
↓ shortened
コンビニ
personal computer
パーソナルコンピューター
↓ shortened
パソコン
Short forms are faster to say, easier to fit into headlines and advertisements, and easier to combine with Japanese grammar.
How to Tell Whether a Katakana Word Will Work in English
If yes, English speakers may not recognize it.
Question 2: Does Japanese use it with unusual partner words?
A combination such as ペーパードライバー may be Japanese-created.
Question 3: Does the sentence meaning feel strange in English?
マンション, クレーム, and テンション require context-based translation.
Question 4: Could it come from another language?
アルバイト comes from German.
Question 5: Is it connected to a Japanese product, company, or cultural history?
バイキング developed from a Japanese restaurant name.
The safest habit is to learn the Japanese meaning and the natural English equivalent as a pair.
How to Learn Wasei-Eigo Without Getting Confused
1. Treat the Word as Japanese Vocabulary
Do not let the English-looking form decide the meaning.
マンション looks like “mansion,” so it must mean a mansion.
Better learning method:
マンション is a Japanese word meaning an apartment building or condominium.
2. Learn the Typical Japanese Collocations
make a complaint
テンションが上がる
get excited
コンセントを抜く
unplug something
バイキングに行く
go to a buffet
バイトをする
work part-time
3. Memorize the Natural English Translation Separately
One Japanese word may require different English translations in different contexts.
energetic / excited / animated / hyper
テンションが下がる
lose enthusiasm / feel disappointed / have one’s mood brought down
テンションについていけない
cannot keep up with someone’s energy
4. Learn the Story Behind Memorable Words
Origins create strong memory links.
バイト becomes memorable when you connect it to German Arbeit.
バイキング becomes memorable when you connect it to the Imperial Viking restaurant.
A Beginner Conversation Full of Japanese English
Kondo, manshon o rifōmu surun da.
I’m going to renovate my apartment soon.
B：いいね。コンセントも増やすの？
Ii ne. Konsento mo fuyasu no?
Nice. Are you adding more electrical outlets too?
A：うん。業者へのクレームが多いらしいから、会社は慎重に選ぶ。
Un. Gyōsha e no kurēmu ga ōi rashii kara, kaisha wa shinchō ni erabu.
Yes. I hear there are many complaints about contractors, so I’ll choose the company carefully.
B：完成したら、家でケーキバイキングしよう！
Kansei shitara, ie de kēki baikingu shiyō!
When it is finished, let’s have an all-you-can-eat cake party at your place!
A：急にハイテンションだね。
Kyū ni hai tenshon da ne.
You suddenly got very excited.
Do Japanese People Know These Words Are Not Natural English?
Some speakers know the difference clearly, especially if they have studied English or used it internationally. Others may assume that a familiar katakana word will work in English.
This is one reason wasei-eigo can cause communication mistakes in both directions:
“I live in a mansion.”
The speaker may simply mean an apartment.
English speaker learning Japanese:
“I know what mansion means.”
The learner may misunderstand the Japanese sentence.
The practical solution is not to declare the Japanese words wrong. It is to understand that switching languages may require switching meanings and expressions.
Are Wasei-Eigo Words Bad Japanese?
No. Once a word becomes established in Japanese, native speakers can use it naturally and productively.
a highly energetic person
クレーム対応
handling customer complaints
ペーパードライバー講習
refresher driving lessons for licensed non-practicing drivers
マンション管理
apartment / condominium management
The words can take Japanese particles, verb forms, modifiers, and compounds. That is evidence that they function as Japanese vocabulary.
Wasei-Eigo in Anime, Manga, and Everyday Conversation
These words appear constantly because they describe ordinary Japanese life.
Kyō, baito nan da.
I have my part-time job today.
コンビニ寄ってく？
Konbini yotte ku?
Want to stop by the convenience store?
なんでそんなにテンション高いの？
Nande sonna ni tenshon takai no?
Why are you so excited?
朝食はバイキングだって。
Chōshoku wa baikingu datte.
They say breakfast is a buffet.
彼、ペーパードライバーらしいよ。
Kare, pēpā doraibā rashii yo.
Apparently, he has a license but rarely drives.
テンション高い might become “You’re excited,” “You’re hyper,” or “You’re in a good mood,” depending on the scene.
Common Beginner Mistakes
Mistake 1: Assuming Katakana Means English
Katakana indicates the writing style, not the source language and not a guarantee of English meaning.
Mistake 2: Translating Each Component Literally
△ paper driver
○ licensed driver who rarely drives
ベビーカー
△ baby car
○ stroller / pushchair
ワンルーム
△ one room
○ studio apartment
Mistake 3: Calling Every Loanword Wasei-Eigo
ホテル and カメラ are ordinary loanwords. アルバイト comes from German. コンビニ is a Japanese abbreviation. The broader label foreign-derived Japanese vocabulary may sometimes be more accurate.
Mistake 4: Believing Every Wasei-Eigo Word Is Completely Unknown in English
Some terms, such as salaryman, have entered English discussions about Japan. However, their use may remain limited to Japanese cultural contexts.
Mistake 5: Memorizing Only an English Gloss
Learn one natural Japanese sentence and one natural English translation.
This apartment building is close to the station.
音楽を聞くとテンションが上がる。
Music gets me excited.
ホテルの朝食はバイキングです。
The hotel serves a breakfast buffet.
FAQ About Wasei-Eigo
What is wasei-eigo?
和製英語 (wasei-eigo) is Japanese vocabulary created by combining, shortening, or changing English elements in ways that do not normally have the same form or meaning in English.
What does wasei-eigo literally mean?
和製 means Japanese-made, and 英語 means English. The literal meaning is “English made in Japan.”
Is wasei-eigo fake English?
“Fake English” is a popular informal description, but it can be misleading. Wasei-eigo words are valid Japanese words; they simply should not be assumed to work as normal English.
Are all katakana words wasei-eigo?
No. Many katakana words are direct loanwords, abbreviations, names, sound effects, or words borrowed from languages other than English.
Is konbini wasei-eigo?
コンビニ is best described as a Japanese abbreviation of コンビニエンスストア, borrowed from the genuine English phrase “convenience store.” It is Japanese-created in form, but its basic meaning remains close to English.
Is baito wasei-eigo?
Strictly speaking, no. バイト is shortened from アルバイト, which comes from German Arbeit. It belongs to the broader category of foreign-derived Japanese vocabulary.

Foreign expressions can become long in Japanese pronunciation. Short forms are easier to say, remember, print, and combine with Japanese grammar.
Can English speakers understand wasei-eigo?
Sometimes they can guess, but many expressions are confusing or mean something different in English. Use the natural English equivalent when speaking English.
