居候 and 同居 both involve sharing a living space — but one has a very specific (and sometimes uncomfortable) nuance!

居候: The Freeloader

居候 (isouro) refers to someone who lives in another person’s home without contributing rent or expenses — often with a connotation of being a burden. It can be used humorously or critically:

  • 実家に居候している。 — I’m freeloading at my parents’ house.
  • 友達の家に居候させてもらっている。 — My friend is letting me crash at their place.
  • あいつはずっと居候だ。 — He’s been freeloading for a long time.

同居: Neutral Living Arrangement

同居 (doukyo) is the neutral term for living together, with no implication of being a burden:

  • 親と同居している。 — I’m living with my parents.
  • シェアハウスで4人で同居している。 — We have four people living together in a share house.

So 居候 always has a negative nuance?

Not always — it can be light-hearted or self-deprecating. But it does carry the idea of “not pulling my weight.”
