How to say "door" in Japanese

• ドアJLPT N5approx.Common
  nounThe everyday word for a door as a physical object — the door of a house, room, or car. It is the usual choice in ordinary speech, especially for Western-style doors.
  このドアは書斎しょさいに通つうじている。↗

  This door leads to the study.
• 扉とびらJLPT N1approx.Common
  nounA door or gate, often a large or imposing one; more literary in flavor than ドア, and used figuratively, as in the door to one's heart. Not the usual word for an everyday house door.
  その扉とびらは永久えいきゅうに閉とざされた。↗

  The door was closed for good.
• 戸とJLPT N5approx.Common
  nounThe native word for a door, used especially for Japanese-style doors such as sliding doors. For an ordinary Western-style door in daily conversation, ドア is the word you will usually hear.
  誰だれかが戸とをやかましくノックしている。↗

  Someone is knocking loudly at the door.
• 戸口とぐちCommon
  nounRefers to the doorway — the opening where a door stands — rather than the door panel itself; use it for someone standing in the doorway. For the door itself, ドア or 戸 fits better.
  支配人しはいにんは戸口とぐちに立たった。↗

  The manager stood at the door.
• 門戸もんこCommon
  nounA formal, mostly figurative word: it appears in set phrases about opening or closing a door to trade, contact, or opportunity. It is seldom the word you want for an actual, physical door.
  １６３９年ねん以降いこう日本にっぽんは外国がいこく料理りょうりに対たいして門戸もんこを閉とざした。↗

  After 1639 Japan closed the door to foreign cuisine.
