Synonyms & antonyms
  • RelatedオープンNeutralA loanword best known for a new store or venue opening (「新店オープン」) and for an open, frank manner (「オープンな人」); it can also mean making something public.
  • Related開放的かいほうてきNeutralAn adjectival noun for people or spaces that feel open and unreserved, as in 「開放的な性格」; it describes a quality, not the act of opening something up.
  • Antonym閉鎖へいさNeutralThe direct antonym: closing or shutting off, as in 「工場閉鎖」; where 「開放」 opens up access, 「閉鎖」 closes or seals it.
  • Antonym密閉みっぺいNeutralMaking something airtight, as in 「密閉容器」; the opposite of 「開放」 for physical spaces — nothing gets in or out.

Use 「開放」 for opening doors and windows or opening a place to the public (「市場開放」「校庭開放」). Say 「オープン」 for a new store opening and 「開放的」 for an open personality; the opposite is 「閉鎖」. Don't confuse with 「解放」 (liberation, release).
