感想を言う

Grammatically, this is a very straightforward 'Object + Particle + Verb' combo. You take 感想 (kansou), add the object marker を (wo), and finish with 言う (iu). Most often, you’ll use it to describe what you did or what someone asked you to do. For example, 映画の感想を言う (say impressions of the movie). You can also use it with the ～た form to talk about something you just did: 感想を言いました (I said my impressions). If you want to sound a bit more polished or if you're in a meeting, you might swap 言う for its fancy cousin 述べる (noberu), but for daily life, 言う is your best friend. Pro-tip: Japanese speakers often use the pattern [Experience] + について + 感想を言う. It’s the 'sandwich' of conversation!

Imagine you’ve just finished a team lunch at a fancy sushi place. Your boss looks at you and says, "How was it?" You are now on the hook to 感想を言う. Or think about a YouTuber finishing a game. They look at the camera and say, "Let me share my final thoughts." That’s a classic 感想を言う moment. On social media, people do this constantly. A tweet that says, "That new anime episode was mid, tbh," is technically 感想を言う in a very 21st-century way. Even when you're texting a friend about a bad date, you're doing it. It's the bread and butter of human interaction. Without it, we'd all just be boring robots reciting Wikipedia entries at each other.

You should pull this phrase out anytime an experience is finished and it's time to reflect. It’s perfect for the 'aftermath' of events: after a concert, after reading a book, or after trying that weird fermented soybean (natto) for the first time. It’s also the go-to phrase in educational settings. In Japan, kids are often asked to write or say their 感想 after a field trip. If you're at a wedding and the bride asks what you thought of the dress, you better be ready to 感想を言う (and make sure it's a good one!). It’s also very useful in job interviews when they ask what you thought of the company's latest project. It shows you’re engaged and have a functioning brain.

Don't use this for objective analysis. If you're a scientist reporting that a chemical turned blue, you aren't giving a 感想; you're reporting a result. Also, avoid using it for simple descriptions. If you say "The sky is blue," that’s just a statement, not an impression. It’s also a bit weird to use it for very trivial things. You wouldn't usually say you're going to 感想を言う about a single grape you just ate—unless that grape changed your life. Furthermore, if you’re in a heated debate and providing a logical argument, 意見を言う (iken wo iu - give an opinion) is much better. 感想 is more 'feelings-based' than 'logic-based'. Using it during a high-stakes legal trial might make you sound a bit too emotional for the room!

One big trap is confusing 感想 (kansou) with 意見 (iken). 意見 is your stance or opinion on a topic (like politics), while 感想 is your personal feeling after an experience (like a movie). Another mistake is using the wrong particle. You can't use に or で here; it’s strictly を because the impression is the thing you are 'producing' with your mouth.

• ✗ 映画に感想を言う → ✓ 映画の感想を言う
• ✗ 私の感想は美味しいです → ✓ 食べた感想を言うと、美味しいです

Sometimes learners try to say 感想を話す (kansou wo hanasu). While people will understand you, it sounds a bit like you’re giving a long speech. 言う is shorter, punchier, and much more natural for a quick chat.

If you want to mix things up, try 感想を伝える (kansou wo tsutaeru). This means "to convey" your impressions, which sounds a bit more intentional and polite. It’s like sending a gift-wrapped thought! For social media addicts, レビューする (rebyu- suru - to review) is very common now. It implies a more structured 'impression' with stars or ratings. Then there’s コメントする (komento suru), which is exactly what it sounds like—leaving a comment on a post or a video. If you’re feeling very formal at work, you can use 所見を述べる (shoken wo noberu), but be careful—you’ll sound like a high-ranking government official or a doctor. Unless you’re wearing a lab coat, stick to 感想を言う!

You’ll often hear this in the potential form: 感想を言える (can say impressions). This is great for when you’re so shocked by a movie that you *can’t* even speak! 感想が言えないほどすごかった (It was so amazing I couldn't even say my impressions). You might also see it as a noun phrase: 感想を言う場 (a place/opportunity to say impressions). In school or workshops, there’s often a 感想を言う時間 (time to say impressions) at the end. Another common one is 一言感想を言う (hitokoto... - to say a brief word of impression). This is the perfect 'escape' when you don't have much to say but don't want to be rude. Just one word and you're done!

Is 感想を言う polite? Yes, it’s perfectly neutral. You can use it with friends or at work. Just change 言う to 言います for the polite version. Can I use it for food? Absolutely! It’s one of the most common ways to talk about a meal. Can I use it for a person? Usually no. You give impressions of *experiences* or *things*, not usually people’s personalities (that’s more like 印象 - inshou). What's the difference between this and 思う (omou)? 思う is just the thought in your head. 感想を言う is the act of actually opening your mouth and letting the thought out. One is internal, the other is external. Can I use it on Instagram? Yes, people use it in captions all the time to introduce their 'take' on a new product or café.
