How to say "regeneration" in Japanese
Choosing the right word
- 新陳代謝しんちんたいしゃnoun, suru verb, intransitive verbA four-character idiom for regeneration as constant renewal, the new replacing the old. It names the body's metabolism, and figuratively the turnover that refreshes an organization or society.
- 再生さいせいnoun, suru verb, transitive verb, intransitive verbThe general-purpose word: regeneration as a return to life, health or function — resuscitation, regrowth after damage, restoration of what was lost. When in doubt, start here.
- 回生かいせいnoun, suru verb, intransitive verbA word for regeneration with the literal image of life coming round again. It overlaps with 再生, the broader term; unless you have a particular reason to choose it, 再生 is the safer pick.
- 代謝たいしゃnoun, suru verb, intransitive verbThe short form of 新陳代謝: chiefly the body's metabolism, and by extension regeneration as the replacement of the old with the new — turnover rather than revival.
- 蘇生そせいnoun, suru verb, intransitive verbRegeneration as coming back to life or regaining vitality: the revival of what seemed dead, or a rejuvenated state — the return of life and vigor rather than rebuilding.
再生 is the default for regeneration as restoration, revival or resuscitation; 新陳代謝 and 代謝 cover renewal that replaces the old with the new; 蘇生 for coming back to life and regained vitality; 回生 is a near-synonym of 再生.
