How to say "curfew" in Japanese

• 門限もんげんCommon
  nounThe everyday word for a curfew as a set time to be home, imposed by parents, a dormitory, or similar; it names the deadline itself rather than an official ban.
  「なあ、寮りょうの門限もんげんって何時いつだっけ？」「２１時じよ」「やばい、走はしらないと間に合まにあわないぞ」↗

  "Hey, when do the dorms lock up?" "9 o'clock." "Whoops, if we don't run we won't make it!"
• 夜間外出禁止令やかんがいしゅつきんしれい
  nounAn official order banning people from going out at night; this is the curfew of news reports about unrest or disaster, not a household rule.
  全ぜん市しに夜間やかん外出がいしゅつ禁止きんし令れいが布しかれた。↗

  A curfew was imposed on the city.
• 外出禁止令がいしゅつきんしれい
  nounAn official order prohibiting people from going out; unlike 夜間外出禁止令 it is not limited to nighttime, and it covers bans imposed during emergencies or disasters.
• 外出禁止がいしゅつきんし
  nounThe ban on going out itself rather than the order announcing it; it covers official curfews and also a child being grounded by parents, matching the grounding sense.
• 晩鐘ばんしょう
  nounReally means the evening bell, and its curfew sense refers to the bell rung as a signal; for an actual ban on going out it is seldom the word you want.

Choose 門限 for a set time to be home, 夜間外出禁止令 or 外出禁止令 for official orders banning going out, 外出禁止 for the ban itself including grounding, and 晩鐘 only for the evening bell.
