How to say "enter" in Japanese

Choosing the right word
  • 入るいるJLPT N1approx.Common
    godan verb, intransitive verbRead いる, this is not the everyday reading for the plain sense 'enter'; that is the はいる reading below. In most learner contexts, if you mean 'enter', you will want はいる rather than いる.
  • 入るはいるJLPT N5approx.Common
    godan verb, intransitive verbThe all-purpose word for 'enter': someone enters, goes in, comes in, or gets in. When you simply mean that someone goes into a room, building, or vehicle with no extra nuance, this is the word to reach for.
    日本にっぽんの家いえに入はいるときには靴くつを脱ぬがなくてはなりません。↗
    You must remove your shoes when you enter a Japanese house.
  • 立ち入るたちいるCommon
    godan verb, intransitive verbTo enter or go into a place, often with the implication of stepping somewhere one should not — hence its 'trespass' sense. It is not the neutral word for simply walking into a room.
  • 上がるあがるJLPT N4approx.Common
    godan verb, intransitive verbUsed for entering from outdoors, such as coming in or being invited in from outside. A narrower word than 入る, so it is not the general verb for 'enter'.
  • 乗り込むのりこむJLPT N1approx.Common
    godan verb, intransitive verbTo enter somewhere forcefully — the 'march into' sense — or to arrive at a place. It suggests entering with force or purpose, not simply walking in; for the plain sense use 入る.
    一人ひとりで原始林げんしりんへ乗り込のりこもうとは君きみはなんて勇いさましいんだ。↗
    How brave of you to go alone into the primaeval forest!

For plain 'enter' use 「入る」(はいる); 「上がる」 covers entering from outdoors, 「立ち入る」 going into or trespassing somewhere, and 「乗り込む」 entering or arriving in a forceful way.
