What Is Gairaigo?
Gairaigo (外来語, literally "words from outside") refers to words borrowed from foreign languages, primarily English in modern times. These words are written in katakana and have been adapted to fit Japanese phonology. For English speakers learning Japanese, gairaigo is both a blessing and a trap. It is a blessing because you can often guess the meaning from the English origin. It is a trap because the pronunciation changes, the meaning sometimes shifts, and some gairaigo words are Japanese inventions that do not exist in English at all.
Direct Borrowings
Many gairaigo words maintain their original English meaning, just with Japanese pronunciation:
- Konpyuutaa (コンピューター): Computer
- Intaanetto (インターネット): Internet
- Sumaatofon (スマートフォン): Smartphone, often shortened to sumaho (スマホ)
- Hoteru (ホテル): Hotel
- Resutoran (レストラン): Restaurant (technically from French)
- Takushii (タクシー): Taxi
- Biiru (ビール): Beer (from Dutch bier)
- Koohii (コーヒー): Coffee
- Chokoretto (チョコレート): Chocolate
Meaning Shifts
Some borrowed words have shifted meaning in Japanese, creating false friends:
- Manshon (マンション): Not a mansion. It means an apartment or condominium building. An actual mansion would be called teitaku (邸宅).
- Kyanpu (キャンプ): Camping, but also used for sports training camps, which would not be called "camp" in English.
- Tenshon (テンション): Not tension or stress. In Japanese, it means energy level or excitement. Tenshon ga takai means being in high spirits.
- Sumaato (スマート): Not smart as in intelligent. It means slim, stylish, or sophisticated in appearance.
- Naiv (ナイーブ): Not naive. It means sensitive or delicate in personality.
Wasei Eigo: Japanese-Made English
Some of the most confusing gairaigo are wasei eigo (和製英語), words that look and sound English but were invented in Japan. English speakers will not recognize these:
- Salaryman (サラリーマン): An office worker, white-collar employee
- Skinship (スキンシップ): Physical affection, bonding through touch
- Baby car (ベビーカー): Stroller or baby carriage
- Gasoline stand (ガソリンスタンド): Gas station
- Morning call (モーニングコール): Wake-up call at a hotel
- Consent (コンセント): Not consent. It means electrical outlet or power socket.
Pronunciation Adaptation Rules
English words are adapted to Japanese phonology following predictable patterns. Japanese syllables typically end in vowels, so consonant clusters get vowel insertions: "strike" becomes sutoraiku (ストライク). The letters L and R merge into a single Japanese sound. The TH sound becomes either S or Z. Understanding these patterns helps you reverse-engineer gairaigo back to its English source. Explore word origins and adapted meanings on KotobaPeek.
