How to say "room" in Japanese

Choosing the right word
  • 部屋へやJLPT N5approx.Common
    nounThe general word for a room as a physical part of a house or building — a bedroom, a hotel room. When 'room' means an actual enclosed room, this is the default choice.
    マユコは部屋へやに入はいった。↗
    Mayuko entered the room.
  • 室しつJLPT N1approx.Common
    noun, noun (suffix)The counterpart of 部屋 in compound words and in the official names of rooms; on its own it is not how you normally refer to a room in speech.
    先生せんせいは生徒せいと達たちに講義こうぎ室しつを退出たいしゅつさせなかった。↗
    The teacher did not permit the students to leave the lecture hall.
  • ルームCommon
    nounThe loanword from English; it turns up mainly in borrowed expressions, and is seldom the natural choice for an ordinary room — for that, 部屋 is the word.
  • スペースJLPT N1approx.Common
    nounThe loanword for 'space'; it fits 'room' meaning free area or capacity — room to move, room for one more — not a room as an enclosed part of a building.
    このあたりは駐車ちゅうしゃできるスペースがほとんどない。↗
    There are few places to park around here.
  • 空間くうかんCommon
    nounSpace as a three-dimensional or abstract extent — open space, the space around you. It can render 'room' in abstract senses, but it is not a word for a room in a building.
    この無限むげんの空間くうかんに漂ただよう永遠えいえんの沈黙ちんもくが私を恐怖きょうふに陥おとしいれる。↗
    The eternal silence of these infinite spaces terrifies me.

Use 部屋 for an ordinary room in a building, 室 in compounds and formal room names, 「ルーム」 in borrowed expressions, and 「スペース」 or 空間 when 'room' means space or capacity rather than an actual room.
