How to say "confine" in Japanese

Choosing the right word
  • 限るかぎるJLPT N3approx.Common
    godan verb, transitive verbCovers the abstract sense of 'confine' as restricting or limiting something within bounds, such as confining a discussion to one topic; it is not the physical sense of shutting someone or something in.
    金持かねもちが必かならずしも幸福こうふくとは限かぎらない。↗
    The rich are not always happy.
  • 封じ込めるふうじこめる
    ichidan verb, transitive verbCovers the physical sense of confining: shutting or sealing something in so it cannot get out, as when trapping something inside an enclosed space or containing it there.
    原子核げんしかくには大量たいりょうのエネルギーが封じ込ふうじこめられている。↗
    A great deal of energy is locked up in the nucleus.
  • 縛り付けるしばりつける
    ichidan verb, transitive verbReally means to tie or bind something down, restraining it physically; its 'confine' sense is only this binding-and-restraining one, so it is seldom the word you want for confining in general.
    彼かれらは泥棒どろぼうを木きに縛り付しばりつけた。↗
    They bound the thief to a tree.
  • 取りこめるとりこめる
    ichidan verb, transitive verbFits the sense of confining by shutting something in or surrounding it, enclosing it within an area; a less common choice that centers on the idea of enclosure.

Use 「限る」 for the abstract sense of restricting or limiting, 「封じ込める」 for sealing or shutting something in, 「縛り付ける」 only for restraining by tying, and 「取りこめる」 for shutting something in by surrounding it.
