Giving Supported Opinions — I can give a short opinion and support it with a simple reason and example.

In everyday conversation, being able to share your opinion is one of the most practical skills you can develop in any language. In Japanese, however, the way people express opinions has evolved over centuries, shaped by cultural values like 和 (wa), meaning "harmony." Japanese speakers traditionally favor indirect expression and consensus-building, which means that learning to state and support your opinion in Japanese requires more than just vocabulary — it requires cultural awareness. Understanding this background helps you sound not only correct but also natural and respectful.

So the central question becomes: how do you clearly state what you think in Japanese, give a reason that makes sense, and support it with a concrete example — all while sounding polite and natural? That is exactly what this lesson will teach you.

Before diving into specific Japanese phrases, you need to understand the underlying structure. A supported opinion in any language follows a three-part pattern: you state your opinion, you explain why you hold it, and you illustrate it with a specific example. In Japanese, each of these parts uses distinct grammar and vocabulary that signal to the listener what role each sentence is playing.

The diagram above is your roadmap for every supported opinion you give in Japanese. Notice how each section has a clear grammatical marker: 「と思います」signals the opinion, 「なぜなら～からです」introduces the reason, and 「たとえば」flags the example. These markers act like signposts for your listener, making your speech organized and easy to follow. When you practice, always check that you have all three layers before finishing your statement.

Now let's break down the specific grammar you need. Each part of the opinion framework uses particular Japanese structures that you should memorize and practice. Below are the essential patterns organized by function.

Stating Your Opinion (意見を述べる)

Giving a Reason (理由を述べる)

Providing an Example (例を出す)

Having a bank of ready-to-use opinion words and topic-related vocabulary will make it much easier to construct your supported opinions on the spot. The diagram below organizes common opinion adjectives and topic nouns you can plug directly into the framework.

When building your sentences, pick a topic noun from the amber box, pair it with an adjective from the cyan or pink box, and connect them using the flow at the bottom. For instance, you could combine 「旅行」(travel) with 「大切な」(important) to say 「旅行は大切だと思います」(I think travel is important). From there, add your reason and example using the connector phrases.

Let's walk through the process of constructing a full supported opinion on the topic: "Is studying a foreign language important?" We'll build it step by step, first in English to plan, and then in Japanese.

Even when you know the structure, certain mistakes come up again and again for learners of Japanese. The table below lists the most frequent pitfalls, along with what the correct version looks like and why the mistake happens.

The Opinion–Reason–Example framework you've learned in this lesson is your foundation, but Japanese argumentation goes much deeper at higher proficiency levels. Understanding where your current skills sit — and where they can go — will help you set goals for growth.

As you progress, you'll learn to acknowledge opposing viewpoints with phrases like 「確かに～しかし」(certainly ~ however) and provide more sophisticated evidence. For now, mastering the three-part framework gives you a solid base. Every advanced argument in Japanese still starts with a clear opinion, a logical reason, and a concrete example — you're building the essential muscle.

Now it's your turn to practice. These five problems increase in difficulty. For each one, try writing your answer before checking the sample response. Remember to use the Opinion–Reason–Example framework and consistent です/ます register.
