嬉しい vs 幸せ
JLPT N3 vocabulary · what is the difference?
嬉しい is a burst of gladness caused by something that just happened — you got a letter, you passed the test. 幸せ is a lasting state of being happy with your life. 嬉しい is normally about how you yourself feel right now, so for other people you say 嬉しそう; 幸せ can be said about others freely, as in 幸せな家族.
When to use each
嬉しい
うれしい
Use 嬉しい for your own immediate reaction to a specific event or piece of news. It normally has a cause, often marked with 〜て or 〜から. About someone else, use 嬉しそう rather than plain 嬉しい.
手紙をもらって嬉しかったです。
てがみをもらってうれしかったです。
I was glad to get your letter.
試験に合格して、とても嬉しいです。
しけんにごうかくして、とてもうれしいです。
I passed the exam, so I'm really pleased.
幸せ
しあわせ
Use 幸せ for a settled condition of happiness — a life, a marriage, a family, or how you feel about your situation overall. It is a な-adjective and also a noun, so 幸せな人生 and 幸せになる are both normal.
家族と一緒にいて幸せです。
かぞくといっしょにいてしあわせです。
I'm happy being with my family.
二人は幸せな家庭を作りました。
ふたりはしあわせなかていをつくりました。
The two of them built a happy home.
Sentences where only one works
プレゼントをもらって嬉しいです。
プレゼントをもらってうれしいです。
I'm glad to have received a present.
One event, one reaction. 幸せ would overstate it, as if the present had changed your life.
今の生活はとても幸せです。
いまのせいかつはとてもしあわせです。
I'm very happy with my life at the moment.
生活 is an ongoing state, so 幸せ. 嬉しい needs a triggering event and does not sit well with 生活.
子どもが嬉しそうに笑っています。
こどもがうれしそうにわらっています。
The child is laughing happily.
Someone else's gladness is reported as 嬉しそう, not plain 嬉しい, because you cannot state another person's inner feeling directly.
あの二人は幸せそうですね。
あのふたりはしあわせそうですね。
Those two look happy, don't they.
幸せ can be said about others plainly too, as in 幸せな家族; here そう just softens it to an impression.
Common mistakes
田中さんは嬉しいです。
田中さんは嬉しそうです。
Plain 嬉しい about a third person sounds like you are reading their mind. Add そう, or report it as 嬉しいと言っていました.
会えて幸せです。
会えて嬉しいです。
Meeting someone is a single occasion, so it calls for 嬉しい. 幸せ here sounds far heavier than intended, like a declaration about your whole life.
Frequently asked questions
Can I say 幸せ about a small nice thing?
Yes, casually — 幸せ over a good cake is common, half-joking. But in ordinary writing, keep 幸せ for the lasting state and use 嬉しい for the moment.
Why does 幸せ take な and 嬉しい not?
幸せ is a noun that also works as a な-adjective: 幸せな家族, 幸せです. 嬉しい is a plain い-adjective: 嬉しい知らせ, 嬉しいです. Their grammar never mixes.
Which do I use to thank someone?
嬉しいです. For example 来てくれて嬉しいです, I'm glad you came. It reacts to what they did, which is exactly what 嬉しい is for.
