How to say "stronghold" in Japanese

• 本拠ほんきょCommon
  nounCovers 'stronghold' as a base of operations or headquarters: the place a person, team, or organization works from and falls back on, whether a literal site or a figurative one.

  Corsairfly is an airline based in Paris.
• 本塁ほんるいCommon
  nounRefers to the main fort or principal stronghold of a defensive position. It is also the baseball term for a base, so for 'stronghold' in general contexts it is seldom the word you want.
• 砦とりでCommon
  nounA concrete fort or fortress: an actual fortified structure or camp built to defend a position. Use it for physical strongholds, not figurative ones.
  砦とりでは不意ふいに攻撃こうげきされた。↗

  The fort was attacked by surprise.
• 要塞ようさいCommon
  nounA fortress in the full military sense: a stronghold heavily fortified to withstand attack. Typical contexts include border defenses and fortified cities.

• 本陣ほんじんCommon
  nounThe main camp of an army in the field — the headquarters position where the commander is based. Its 'stronghold' sense is this military main camp, not a fortress or a figurative base.

本拠 is the word for a base or headquarters, 砦 and 要塞 for physical fortifications (a fort versus a full fortress), 本陣 for an army's main camp, and 本塁 mainly for a main fort.
