English 'inevitably' is often used as a discourse marker to introduce an expected outcome. In Japanese, directly translating it as 必然的に (hitsuzen-teki ni) can sound overly formal or stiff. Instead, use more natural adverbs like 当然 (touzen) or 必ず (kanarazu), or rephrase the sentence to show natural consequence.
当然 (touzen) emphasizes logical or natural consequence, while 必ず (kanarazu) stresses certainty and invariability. 当然 is more about 'as expected', 必ず is more about 'without exception'.
彼は当然怒るだろう。
He will naturally get angry.
彼は必ず怒る。
He always gets angry.
