How to say "endless" in Japanese

• 限りないかぎりないCommon
  i-adjectiveCovers the 'without limit' sense: boundless, infinite quantities or space. Fits things conceived as having no limit at all, such as possibilities or the universe.
• エンドレスCommon
  na-adjectiveThe katakana loanword, used much as in English for something that simply goes on and on without stopping — a discussion, a game, a loop. It stresses continuous repetition or continuation.
• 果てしないはてしないCommon
  i-adjectiveEmphasizes that something stretches on with no end in sight, whether across space or through time: a boundless plain, an everlasting wait, a talk that seems it will never finish.
  この果はてしない宇宙うちゅうにいるのは、私わたしたち人類じんるいだけですか？↗

  Are we humans alone in this infinite universe?
• きりがないCommon
  expression, i-adjectiveAn idiomatic predicate meaning 'there is no end to it', for open-ended amounts of work, talk, or complaints; usually written in kana alone.
  彼かれの野心やしんにはきりがない。↗

  His ambition knows no bounds.
• 野放図のほうずCommon
  na-adjective, nounNot a general word for endless: it means uncontrolled or rampant, and its 'endless' use applies to things left unchecked, such as runaway spending. The nuance is lack of control, not mere duration.

Choose 「限りない」 for limitless amounts, 「果てしない」 for things stretching on with no end in sight, 「きりがない」 when there is no end to tasks or talk, 「エンドレス」 as the katakana loanword, and 野放図 only for unchecked, runaway behavior.
