How to say "international" in Japanese

Choosing the right word
  • 国際こくさいJLPT N4approx.Common
    no-adjectiveThe default choice when you simply mean 'international'; unless you have a specific reason to pick one of the others, this is the word to reach for.
    We are having an international trade fair this month.
  • インターナショナルJLPT N1approx.Common
    na-adjective, nounThe katakana loanword; it carries an English-language flavor and appears most often in names and set phrases, so 国際 is the natural choice for translating 'international' in a sentence.
  • 国際的こくさいてきCommon
    na-adjectiveCovers 'international' as a descriptive adjective — something international in character or scope — and stretches to 'worldwide' and 'cosmopolitan'; fits descriptions of cities, events, or people with an international outlook.
    麻薬まやく汚染おせんの問題もんだいは国際的こくさいてきである。↗
    The drug problem is international.
  • 世界的せかいてきCommon
    na-adjectiveReally means 'worldwide' or 'global' — of world scale or known the world over; 'international' is only a secondary rendering, so pick it for global reach or worldwide fame, not plain 'international'.
    トルストイは世界的せかいてき名声めいせいを博はくした。↗
    Tolstoy achieved worldwide fame.
  • nounA clipped abbreviation of インターナショナル rather than a word in its own right; it is seldom the word you want for 'international' — use 国際 there instead.

Use 国際 for 'international' in ordinary contexts, 国際的 when describing something as international or cosmopolitan in character, 世界的 for the worldwide/global sense, and the loanword 「インターナショナル」 (clipped 「インター」) mainly in names.
