• RelatedよんどころないWrittenWritten. Expresses helpless resignation — having no alternative; it points to being compelled by circumstances, not to causal necessity.
• Related致し方ないいたしかたないNeutralNeutral. Means there is no other way; more dignified and polite than 「仕方ない」. It conveys helplessness, not logical necessity.
• RelatedやむないNeutralNeutral. Means unavoidable, leaving no choice; close in sense to 「やむを得ない」, stressing that one is forced by circumstances.
• Related是非無いぜひないWrittenWritten, old-fashioned and rare; modern Japanese says 「仕方ない」 instead. Conveys that something cannot be helped.
• Related回避不能かいひふのうWrittenWritten. An explanatory, businesslike term for something that cannot be avoided or evaded; stresses being inescapable, not causal necessity.
• Antonym偶然的NeutralAntonym. Means happening by chance; the opposite of the causal necessity that 「必然的」 expresses.

Use 「必然的」 for what must be so by reason or logic, as in 「必然的な結果」. For what cannot be avoided, choose 「不可避」; for what is bound to happen, 「必至」. When the nuance is being forced or having no choice, turn to 「余儀ない」, 「やむない」 or 「致し方ない」. The opposite is 「偶然的」.
