How to say "commune" in Japanese

• コミューン
  nounThe loanword, covering 'commune' in its general sense — a community whose members live together and share property, or a self-governing community — rather than the medieval European commune specifically.
• 自治都市じちとし
  nounLiterally 'self-governing city'. It renders the medieval European commune, stressing the city's self-rule, and can also mean an autonomous city in general. Typical context: historical writing on medieval Europe.
• 自由都市じゆうとし
  nounThough it can stand for the medieval European commune, the word really means 'free city', and as a rendering of 'commune' it is marginal; it fits best when the English itself says 'free city'.

For 'commune' in its general sense use the loanword 「コミューン」; for the medieval European commune 自治都市 stresses self-rule, while 自由都市 really means 'free city' and is only a marginal match; all three are relatively uncommon.
