How to say "gateway" in Japanese

• 関門かんもんCommon
  nounA gateway that doubles as a barrier or checkpoint: a point of passage that controls what goes through, literal or figurative. It fits a guarded gate and, figuratively, a hurdle that must be cleared.
  これ以上いじょうここでもたついてると、後うしろの第だい二に関門かんもんからも増援ぞうえんが来きて、挟撃きょうげきされるかも知しれねーんだぜ。↗

  If we hang around here any longer, there could be reinforcements coming from the second gate to take us in a pincer movement!
• ゲートウェイ
  nounA direct borrowing of the English word. It is the word to use when the English term itself would be kept, notably in technical contexts such as computer networks.
• 門口かどぐち
  nounThe literal entrance of a house or building — the doorway or gate opening itself. A less common option for 'gateway', and a physical entrance rather than a figurative one.
• 玄関口げんかんぐち
  nounLiterally the front entrance of a house; for 'gateway' it covers the figurative sense of a region's main point of entry, such as a port city opening the way to the region beyond.

Choose 玄関口 for a region's point of entry, 関門 for a gateway that is also a barrier or checkpoint, 門口 for a physical entrance, and the loanword 「ゲートウェイ」 where the English term itself fits.
