I want to say ‘I take care of my little sister’ in Japanese. Should I use 世話をする or 面倒を見る?


Great question! Both mean caring for someone, but they have slightly different nuances and registers. Let me break them down!
Both 世話をする(せわをする) and 面倒を見る(めんどうをみる) mean “to take care of” or “to look after” someone, but they differ in nuance and typical usage contexts.
At a Glance
| 世話をする (sewa wo suru) | 面倒を見る (mendou wo miru) | |
|---|---|---|
| Core meaning | To take care of, to look after | To look after, to take responsibility for |
| Nuance | General care, helping, tending to | Hands-on responsibility, often long-term |
| Can be used for | People, animals, plants | People (especially dependents) |
| Register | Neutral | Neutral to slightly more serious |
| Set phrase | お世話になる (to be in someone’s care) | 面倒を見てもらう (to be looked after) |
世話をする: General Care and Helping
世話をする covers a wide range of caring activities — from helping a person to tending a garden:
- 妹の世話をしている。— I take care of my little sister.
- 猫の世話をするのは大変だ。— Taking care of a cat is hard work.
- 花の世話をしている。— I tend to my flowers.
- 新入社員の世話をする。— To look after new employees.
- お世話になっています。— Thank you for your continued support. (set phrase)
面倒を見る: Responsibility and Oversight
面倒を見る implies taking on responsibility for someone — often with a sense of ongoing commitment or oversight:
- 祖母の面倒を見ている。— I look after my grandmother. (ongoing responsibility)
- 子供の面倒を見る。— To look after children.
- 部下の面倒を見る。— To take responsibility for one’s subordinates.
- ペットの面倒が見られなくなった。— I can no longer look after my pet.
- 彼女は面倒見がいい。— She’s good at taking care of people / very caring.


So 面倒を見る feels more like taking on a duty, while 世話をする is more about the act of caring day-to-day?


Exactly! And notice 面倒見がいい — that’s a great compliment meaning someone is genuinely caring and attentive to others. 世話をする doesn’t have that same fixed personality compliment form.
お世話になる: The Essential Set Phrase
お世話になっています / お世話になりました are essential expressions of gratitude used constantly in Japanese business and daily life:
- いつもお世話になっております。— Thank you for your continued support. (business email opener)
- 先生には大変お世話になりました。— My teacher took such good care of me / I’m deeply grateful to my teacher.
- お世話になった人に感謝する。— To express gratitude to someone who has looked after you.
