【Modern Japanese】Writing Logical Texts! 〜Rules for Effective Communication〜

Hello everyone! Have you ever felt like "I'm not good at writing essays or compositions" or "I don't know what to write about"?
Actually, you don't need magical talent to write a logical text. By simply learning a few "structures" and "rules," anyone can write something that makes the reader think, "Aha! That makes sense!"
In this unit, let's master the basics of clearly conveying your own thoughts. It might feel difficult at first, but try to enjoy it as if you were putting together a puzzle!

1. What is a logical text?

In short, a logical text is a "well-reasoned piece of writing that anyone can find convincing." It’s a bit different from an "essay," where you can write freely about your feelings.
The goal of a logical text is to "persuade" the reader. To do that, the following three elements are essential:

1. Claim (What you want to convey most/your conclusion)
2. Grounds (The reason why your claim is valid)
3. Facts (Data or specific examples that support your grounds)

【Tip!】
It is only when the Claim, Grounds, and Facts work together that "persuasiveness" is born. If any one of them is missing, the reader will be left wondering, "But why?"

2. Learn the structure: Introduction, Body, and Conclusion

When writing, don't just start writing immediately. First, think about the "structure (the blueprint)." The most common format is the following three-part structure:

(1) Introduction (The Beginning)

Here, present "what theme you will be discussing." It is also helpful for the reader if you state your "claim (conclusion)" upfront.
Example: "I believe that social media usage time should be limited. This is because..."

(2) Body (The Middle)

This is the largest section where you write out the "grounds" for your claim in detail. Incorporating "objective facts"—such as specific anecdotes, statistics, or numerical data—increases your persuasiveness.
Example: "In fact, research results show that late-night social media use leads to sleep deprivation. For instance..."

(3) Conclusion (The Ending)

This is the summary of the whole piece. Based on your explanation in the body, reiterate your "claim" once more. Ensure it doesn't contradict what you stated in the introduction.
Example: "For the reasons mentioned above, limiting social media use is necessary to protect our health."

【Fun Fact: The Hamburger Method】
The structure of a text is like a hamburger. Imagine the top bun (Introduction) and the bottom bun (Conclusion) securely holding the patty and lettuce (Body) in the middle!

3. Distinguishing between "Facts" and "Opinions"

The most important part of a logical text is clearly separating "Facts" from "Opinions." If these get mixed up, your writing will come across as self-centered.

Fact: Something that doesn't change regardless of who observes it. Objective data or events that actually occurred.
(Example: The temperature exceeded 30 degrees today.)
Opinion: Your own thoughts or judgments. Something that varies from person to person.
(Example: It is very hot today, so it’s hard to get through.)

【Common Mistakes】
If you use "I think..." too much, everything sounds like a personal impression. Try to focus on the structure of "There is data that... (Fact)" + "Therefore, I think that... (Opinion)."

4. Master the use of conjunctions (linking words)

Conjunctions make the connection between sentences smooth. They act like "road signs" for your writing.

Consecutive (Continuing logically from the previous content): Therefore, accordingly, hence
Adversative (Presenting something opposite to the previous content): However, but, nevertheless
Exemplification (Giving a specific example): For example, specifically
Addition (Adding information): Also, furthermore, in addition

By using the right conjunctions, the reader can follow your train of thought without getting lost, wondering "What comes next?"

5. How to create reader-friendly paragraphs

In logical writing, there is a rule: "Write only one topic per paragraph." This is called "one paragraph, one idea."

1. At the beginning of the paragraph, write the main point of that paragraph (Topic Sentence).
2. Follow that with specific explanations or reasons.
3. Always start a new line when the topic changes.

【Checklist!】Verify these when you're finished!
□ Do the subject and predicate match correctly? (e.g., "My dream is I want to be a doctor" → "My dream is to become a doctor")
□ Is it clear what words like "that" or "this" are referring to?
□ Are the sentence endings unified (e.g., using "da/dearu" or "desu/masu")?
□ Is any sentence too long? (Break them up appropriately with periods)

Summary: Steps to writing a logical text

1. Preparation: Decide what you are writing about and clarify your opinion.
2. Structure: Make a rough outline of your Introduction, Body, and Conclusion.
3. Writing: Distinguish between facts and opinions, and connect them using conjunctions.
4. Review: Read it aloud to ensure the flow is logical.

It's perfectly fine to start with short texts. Even in a diary or a social media post, if you practice the structure of "Something happened today (Fact). The reason is... (Reason). Therefore, I thought... (Opinion)," you will develop logical thinking skills in no time! Let's work hard together!
