How do I express my opinion or preference in Japanese
How to express an opinion or preference in Japanese
The most common way to express an opinion in Japanese is と思う for casual speech or と思います for polite speech, both meaning “I think.” The basic pattern is simple: place と思う／と思います after the statement, adjective, or noun phrase that carries the opinion.
The core pattern: 〜と思う
Japanese often softens opinions by framing them as a personal thought rather than an absolute fact. That makes と思う one of the most useful conversation phrases in the language.
For い-adjectives and verbs
With い-adjectives and verbs, the statement can usually go directly before と思う.
-
この曲、めっちゃかっこいいと思うよ。
(Kono kyoku, meccha kakkoii to omou yo.)
“I think this song is really cool.” -
この映画は面白いと思う。
(Kono eiga wa omoshiroi to omou.)
“I think this movie is interesting.” -
明日は雨が降ると思う。
(Ashita wa ame ga furu to omou.)
“I think it will rain tomorrow.”
This form is especially natural when giving a personal impression, predicting something, or stating a belief that is not presented as certain fact.
For な-adjectives and nouns
With な-adjectives and nouns, Japanese usually needs だ before と思う in casual speech.
-
大切だと思うよ。
(Taisetsu da to omou yo.)
“I think it’s important.” -
彼はいい人だと思います。
(Kare wa ii hito da to omoimasu.)
“I think he is a good person.” -
静かだと思う。
(Shizuka da to omou.)
“I think it’s quiet.”
In polite speech, the same structure is used, but the ending changes to 思います.
Polite and casual choices
The difference between 思う and 思います is mainly register:
- 思う: casual, friendly, everyday speech
- 思います: polite, suitable for teachers, coworkers, customers, and formal situations
The meaning stays the same, but the social tone changes. In real conversation, the ending often signals as much as the grammar. Japanese speakers regularly choose softer phrasing when disagreeing or offering a personal view, because direct statements can sound too blunt.
Adding emphasis or softness
Japanese has several small endings that can change the feel of an opinion:
- よ adds a sense of sharing information or emphasizing the speaker’s view.
- ね seeks agreement or shared feeling.
- かな sounds uncertain or self-questioning.
- でしょう／だろう can sound like a guess, prediction, or soft assertion depending on context.
Examples:
-
この店、おいしいと思うよ。
“I think this restaurant is tasty.” -
この店、おいしいと思うね。
“I think this restaurant is tasty, don’t you?” -
この店、おいしいかな。
“I wonder if this restaurant is tasty.”
Expressing preference
To say what is liked or preferred, Japanese often uses 好き or 好む-type expressions rather than a direct “I prefer” structure.
Basic preference with 好き
-
日本の音楽が好きです。
“I like Japanese music.” -
コーヒーよりお茶のほうが好き。
“I like tea better than coffee.”
The pattern A より B のほうが好き is very common for comparing preferences. It is clear, natural, and easy to use in conversation.
Saying what is better
When comparing options, Japanese often uses:
- 〜のほうがいい = “is better”
- 〜より…のほうが好き = “prefer … to …”
Examples:
-
家で勉強するほうがいい。
“Studying at home is better.” -
大きい部屋のほうが好きです。
“I prefer a bigger room.” -
コーヒーより紅茶のほうが好きです。
“I prefer tea to coffee.”
Other useful opinion expressions
Besides と思う, Japanese has several common ways to give opinions with slightly different nuance.
〜と思いますが
This form is useful when presenting an opinion gently, especially before a suggestion or disagreement.
- 少し高いと思いますが、品質はいいです。
“I think it’s a little expensive, but the quality is good.”
The が softens the statement and can make the opinion sound less forceful.
〜ように思う
This sounds a little more reflective or indirect than plain と思う.
- 彼の説明は少しわかりにくいように思う。
“I feel that his explanation is a little hard to understand.”
〜気がする
This is often used for intuition, impression, or a vague feeling.
- 今日はうまくいく気がする。
“I feel like today will go well.”
This expression is especially common when the speaker is not fully certain.
Speculation and probability: だろう and でしょう
Another way to express a view is to use だろう or でしょう, which often suggest probability, assumption, or a softer prediction.
-
明日はいい日になるだろう。
(Ashita wa ii hi ni naru darou.)
“Tomorrow will probably be a good day.” -
彼はもう着いたでしょう。
“He has probably arrived already.”
Compared with と思う, these forms often sound more detached. They are useful when the speaker is estimating an outcome rather than stating a personal opinion.
Asking someone else’s opinion
To ask for another person’s view, the most direct and natural phrase is:
- このことについてどう思いますか？
(Kono koto ni tsuite dou omoimasu ka?)
“What do you think about this?”
Other common versions include:
- どう思う？
“What do you think?” - これ、どう思いますか？
“What do you think of this?”
These are extremely common in Japanese conversation, meetings, and daily decision-making. In speaking practice, repeated use of these patterns helps build quick, natural responses because opinions are often exchanged in short turns rather than long explanations.
Common pitfalls
1. Forgetting だ with nouns and な-adjectives
A frequent mistake is saying a noun or な-adjective directly before と思う without だ in casual speech.
- Correct: 大切だと思う。
- Incorrect: 大切と思う。
2. Using overly direct language in polite settings
In formal situations, 思います is usually safer than 思う. A casual ending can sound too abrupt if the setting is professional or unfamiliar.
3. Confusing opinion with fact
と思う softens a statement by showing it is a thought, not an absolute claim. That makes it useful in Japanese, where indirectness often sounds more considerate than blunt certainty.
Quick reference
- I think… → 〜と思う／〜と思います
- I think it’s important. → 大切だと思う
- I think he is a good person. → 彼はいい人だと思います
- I like tea better than coffee. → コーヒーより紅茶のほうが好きです
- What do you think? → どう思いますか？
In summary, と思う／と思います is the most natural and flexible way to express an opinion in Japanese, while 好き, 〜のほうがいい, だろう／でしょう, and 気がする cover preference, comparison, prediction, and intuition.
