How to say "renewal" in Japanese

• 更新こうしんCommon
  noun, suru verb, transitive verb, intransitive verbThe everyday word for renewing or updating: extending the validity of a contract, license or membership, or bringing data and content up to date. For plain 'renew' or 'update', this is the safe choice.
  この冬ふゆは降雪量こうせつりょうの記録きろくを更新こうしんした。↗

  This winter the record for snowfall was broken.
• リニューアルCommon
  noun, suru verb, transitive verbA loanword for giving something a fresh start by renovating or overhauling it: a shop or hotel refurbished, a website redesigned, a product relaunched in improved form. The flavour is 'revamp'.
• 維新いしんCommon
  nounNot everyday renewal at all: this word means sweeping reformation or revolution — the wholesale remaking of a nation or its institutions, as in the Meiji Restoration. Seldom the word you want for ordinary 'renewal'.
• 更改こうかいCommon
  noun, suru verb, transitive verbA business and legal term for renewing a contract, typically extending it on revised terms rather than simply repeating the old ones. For paperwork and negotiations, not for renovating buildings or updating websites.
• 新陳代謝しんちんたいしゃCommon
  noun, suru verb, intransitive verbLiterally the body's metabolism: the ongoing replacement of old cells with new, and figuratively the regeneration or rejuvenation of an organization or society as old elements give way to new. Not for documents or contracts.

Choose 更新 for routine renewal or updating of contracts, licenses and data; 「リニューアル」 for renovating or overhauling shops, sites and products; 更改 for renewing a contract on revised terms; 新陳代謝 for natural regeneration; 維新 for sweeping reformation or revolution.
