55 Wasei-eigo Words: Japanese "English" That Native Speakers Won't Understand
Wasei-eigo means "Japan-made English": words built from English parts that mean something different, or nothing at all, to native speakers. A manshon is not a mansion, and a konsento has nothing to do with consent. For visitors, these words are easy to learn because they already sound familiar. For Japanese learners of English, they are the words most likely to cause a blank stare.
📝 Before you start
- Don't assume a katakana word works in English. If it sounds like English, check it before you use it abroad.
- Many wasei-eigo words are perfectly normal Japanese. They are not mistakes inside Japan; they only fail when you use them in English.
- Some katakana words come from other languages, not English. Arubaito is German and randoseru is Dutch, so they were never English to begin with.
- When you don't know the English word, describe it. "The thing you plug into the wall" gets you further than konsento.
- For visitors: when a Japanese person uses an odd English word, think of the katakana version. A "mansion" in conversation is almost always an apartment.
