How to say "recovery" in Japanese

• 回復かいふくJLPT N3approx.Common
  noun, suru verb, transitive verb, intransitive verbThe default word for recovery as a return to a normal or former state: health after illness, the economy after a slump, relations after a falling-out. It also covers rehabilitation and restoration.
  回復かいふくはほとんど不可能ふかのうだった。↗

  Recovery was almost impossible.
• 回収かいしゅうJLPT N1approx.Common
  noun, suru verb, transitive verbRecovery in the physical or financial sense of getting something back: collecting debts, recouping costs, retrieving items or withdrawing products from sale. Not the word for a return to health or normal conditions.
  いよいよ賭け金かけきんを回収かいしゅうするときがきました。↗

  It's time to call in our chips.
• 取り返しとりかえしCommon
  nounRegaining something lost or undoing damage, but seldom a standalone noun: it lives mainly in set phrases about losses that can never be made good. Rarely the word you want for 'recovery'.
• 奪還だっかんCommon
  noun, suru verb, transitive verbRecovery by force or determined effort — recapturing territory, retaking a title, taking back hostages or seized property. It presupposes something held by another party, so it never suits health or the economy.
• 戻りもどりCommon
  nounA coming back or return to an earlier level or position; in market talk it names a rebound after a fall. For recovery of health or conditions, 回復 remains the natural choice.

Choose 回復 for a return to health or normal conditions; 回収 for getting things back, such as debts or costs; 奪還 for retaking something by force; 「戻り」 for a rebound; 「取り返し」 is largely confined to set phrases.
