How do I express my opinion or preference in Japanese
To express your opinion or preference in Japanese, the most common and straightforward way is to use the verb と思う (to omou) or its polite form 思います (omoimasu), which means “I think.” You place と思う／と思います after the statement expressing your opinion.
Here are some examples of how to use it:
-
For い-adjectives or verbs:
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.” -
For な-adjectives and nouns, add だ before と思う:
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 great guy.”
This construction is used for expressing personal opinions or things you assume to be true, and the tone can be casual (思う) or polite (思います) depending on the context.
Deeper Explanation: Why Use と思う？
The phrase と思う literally translates to “think,” but it has a broader function in Japanese beyond just cognitive thought. It softens statements, making opinions less direct or confrontational, which fits the Japanese communication style that values harmony and non-assertiveness. For example, while in English saying “This is good” can sound confident or assertive, attaching と思う makes it more of a gentle suggestion or personal feeling: “I think this is good.”
When using と思う, you also shift the focus to your personal perspective rather than stating an absolute fact, which is important in Japanese where humility and politeness play large roles.
Alternatives to と思う for Expressing Preference and Opinion
While と思う is very common, different situations call for different nuances or levels of politeness.
1. Using かな (kana) - Casual Wondering or Preference
Adding かな at the end of a sentence adds a nuance of wondering or slight doubt, often used when pondering one’s own preference internally or casually.
Example:
このラーメン、いいかな？
(Kono rāmen, ii kana?)
”I wonder if this ramen is good (I think I might like it).“
2. Using 好き (suki) and 嫌い (kirai) to State Preferences Directly
If you want to state likes or dislikes clearly, 好き (like) and 嫌い (dislike) are direct and very natural.
Example:
私は日本料理が好きです。
(Watashi wa nihon ryōri ga suki desu.)
”I like Japanese food.”
私は辛い食べ物が嫌いです。
(Watashi wa karai tabemono ga kirai desu.)
”I dislike spicy food.”
This straightforward expression is very common when stating preferences without needing to soften the statement.
3. Using ほうがいい (hō ga ii) for Advice or Preference Between Options
When comparing two options and expressing a preference, ほうがいい is useful. It literally means “is better if.”
Example:
夏は海に行ったほうがいいと思います。
(Natsu wa umi ni itta hō ga ii to omoimasu.)
”I think it’s better to go to the beach in summer.”
4. Using 〜のが好き (no ga suki) to Specify Activities or Preferences
This structure is often used to specify an action or thing you like.
Example:
映画を見るのが好きです。
(Eiga o miru no ga suki desu.)
”I like watching movies.”
Common Mistakes When Expressing Opinions in Japanese
1. Omitting だ before と思う with Nouns and な-adjectives
For beginners, a common mistake is forgetting to add だ before と思う when the opinion includes a noun or な-adjective.
Incorrect:
彼はいい人と思う。
Correct:
彼はいい人だと思う。
2. Using と思う for Objective Facts
Avoid using と思う for stating facts that are not opinions or assumptions. Instead, use です or plain forms. For example, saying “今日は暑いと思う” (I think today is hot) is fine as an opinion, but if insisting it’s a fact or reporting temperature objectively, just say “今日は暑いです.” Using と思う for non-opinion statements can sometimes sound hesitant or uncertain unnecessarily.
3. Overusing と思う in Formal Writing
In very formal contexts like business emails or presentations, using 思います repeatedly can sound too subjective. Alternative expressions such as と考えます or ように思います might offer a more professional tone.
Step-by-Step: How to Form an Opinion Sentence Using と思う
-
Identify your opinion phrase. This can be an adjective, verb, or noun that expresses your viewpoint.
Example: 「美味しい」(delicious) or 「彼は先生だ」(He is a teacher). -
Adjust the phrase:
- For い-adjectives and verbs, place them directly before と思う.
- For nouns and な-adjectives, insert だ before と思う.
-
Attach と思う or 思います depending on your speech style (casual or polite).
-
Optionally add sentence-ending particles like よ or ね to add emphasis or seek agreement.
-
Complete the sentence.
Example:
- Casual: このケーキは美味しいと思うよ。
- Polite: このケーキは美味しいと思います。
