How to say "foreign" in Japanese

Choosing the right word
  • 海外かいがいJLPT N3approx.Common
    no-adjectiveCovers 'foreign' in the sense of 'abroad' or 'overseas' — foreign countries seen from one's own. The word to use for overseas travel, business, study, or news.
    君きみはどれくらいよく海外かいがいに行いきますか。↗
    How often do you go abroad?
  • 外来がいらいJLPT N1approx.Common
    no-adjectiveCovers 'foreign' as 'imported' — something that has come in from outside, such as a word, plant, or custom from abroad. It mostly appears inside compounds rather than standing alone.
    君きみは外来がいらい思想しそうに偏見へんけんを抱いだいているようだ。↗
    You seem to be prejudiced against ideas that come from foreign countries.
  • 対外たいがいCommon
    prenominal modifier, nounCovers 'foreign' in the relational sense of 'toward foreign countries' — dealings, relations, or policy with other countries. Not a word for foreign things themselves, and mostly seen in compounds.
    The Secretary of State administers foreign affairs.
  • 洋式ようしきCommon
    no-adjectiveReally means 'Western-style': a style or format of Western origin, as in a Western-style room or toilet. Only marginally 'foreign' — not the word for foreign countries, people, or languages.
    私は洋式ようしきのホテルに泊とまりたい。↗
    I'd like to stay in a Western-style hotel.

Choose 海外 for foreign countries as places, 外来 for things imported from outside, 対外 for relations directed toward foreign countries, and 洋式 only for Western-style rooms, toilets, and the like.
