How to say "naturally" in Japanese

• もちろんJLPT N4approx.Common
  adverbCovers the conversational sense of 'naturally' meaning 'of course' or 'certainly' in reply to a question or to state the obvious. This is usually the word you want for that use, and it is normally written in kana.
  「ご一緒いっしょしてもいいですか」「もちろんです」↗

  "May I go with you?" "Of course."
• おのずからJLPT N1approx.Common
  adverbMeans 'naturally' in the sense of happening by itself or of its own accord, without outside prompting, often 'in due course'. It does not mean 'of course'; use it for outcomes that arise spontaneously.
  油断ゆだんなく注意ちゅういさえしておれば好機こうきはおのずからうまれる。↗

  Plenty of opportunities will present themselves, if only you are awake to them.
• 無論むろんJLPT N1approx.Common
  adverbA synonym of もちろん, covering the same 'of course; certainly; naturally' sense. Like もちろん it is used for obvious or conceded statements, but it is written with kanji and has a somewhat more formal, written feel.
  むろん信用しんようしていいとも。君きみにヨタ情報じょうほうを教おしえたことが一度いちどでもあったかい。↗

  Of course you can trust me. Have I ever given you a bum steer before?
• 生まれつきうまれつきJLPT N1approx.Common
  adverb, no-adjectiveCovers 'naturally' in the sense of 'by nature; by birth', describing traits, abilities or dispositions a person has from birth, as in being naturally talented or naturally shy.
  この生うまれつきのあざに悩なやんでいます。↗

  I'm troubled by this birth-mark.
• 元来がんらいJLPT N1approx.Common
  adverbMeans 'naturally' as 'by nature' or 'essentially', describing how someone or something fundamentally is. It points to inherent character rather than birth specifically, and also carries the sense of 'originally'.
  元来がんらいフットボールとは、ポロのように馬うまに乗のって行おこなわれる競技きょうぎとは違ちがって、足あしで、ボールを使つかって行おこなわれる競技きょうぎのことでした。↗

  Football originally meant "a game played with a ball on foot" - unlike a game played on horseback, such as polo.

Use 「もちろん」 or 無論 for 'of course, naturally' as agreement, 「生まれつき」 for innate traits, 元来 for inherent character, and 「おのずから」 for things happening by themselves.
