居候 and 同居 both involve sharing a living space — but one has a very specific (and sometimes uncomfortable) nuance!
| Word | Reading | Meaning |
|---|---|---|
| 居候 | isouro | freeloader / live-in dependent / someone living off others |
| 同居 | doukyo | living together (neutral / practical arrangement) |
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.”
Key Contrast
| Word | Nuance |
|---|---|
| 居候 | Living off others / not contributing / freeloader |
| 同居 | Living together (neutral — can contribute or not) |
