Why Repetition Matters More Than Explanation

Thank you always for watching my videos! Until now, all scripts and study PDFs for the “Simple Japanese” series were available directly on my website. Starting from Episode #70 (“My Town”), the PDFs will now be provided through Ko-fi. In addition, PDFs for Episodes #1–#69 will also be gradually moved to Ko-fi. ※They will remain free, just as before. The main reason for this change is that uploading many PDF files directly to my website makes the site heavy and slows down its performance. To keep the website fast and easy to use, I will now host the PDFs on Ko-fi instead. Thank you very much for your understanding and continued support!

Many Japanese learners feel stuck even though they are studying seriously.

They read grammar books.
They watch explanation videos.
They understand the rules.

And yet, their Japanese does not move.

When this happens, the problem is rarely a lack of explanation.
More often, it is a lack of repetition.

Explanation creates understanding—but not familiarity

Explanations are useful.

They help you notice patterns.
They reduce confusion.
They give structure to what you are learning.

But explanation alone does not make language usable.

Understanding a rule is not the same as being able to use it.
And knowing why something works does not mean your brain can process it automatically.

Language becomes natural through familiarity, not insight.

The brain learns language through repeated contact

Your brain does not treat language as information.
It treats it as experience.

Each time you hear the same expression:

  • in a similar situation

  • with a similar meaning

  • in a familiar rhythm

your brain becomes less analytical and more predictive.

This is how processing speed increases.

Not because you learned more rules,
but because your brain no longer needs to think.

Why repetition often feels “inefficient”

Many learners avoid repetition because it feels slow.

You think:

  • “I already know this.”

  • “This is too easy.”

  • “I should move on.”

But repetition is not about learning new things.
It is about deepening what you already know.

What feels boring at the conscious level is often exactly what your unconscious learning system needs.

Explanation answers questions. Repetition removes questions.

When you rely on explanation, questions remain:

  • “Is this correct?”

  • “Which form should I use?”

  • “Why is it like this?”

With enough repetition, those questions disappear.

You don’t choose expressions.
They appear.

This is the difference between studying Japanese and using Japanese.

Stories make repetition natural

One reason repetition is hard to accept is that drills feel mechanical.

Stories solve this problem.

In stories:

  • the same expressions appear naturally

  • meaning is reinforced through context

  • repetition feels purposeful, not artificial

You are not repeating language.
You are following events.

And repetition happens quietly in the background.

Why more explanation can slow progress

When learners feel stuck, they often ask for more explanation.

But more explanation increases cognitive load.

Instead of strengthening existing connections, your brain is asked to:

  • analyze again

  • compare rules

  • hold multiple options at once

This keeps language in the realm of thinking, not processing.

Repetition does the opposite.
It simplifies.

Final thought

Explanation helps you understand Japanese.

Repetition helps you use Japanese.

If you feel like you are studying a lot but moving slowly,
the solution may not be another explanation.

It may be hearing the same simple Japanese—again, and again, and again—until it no longer feels like study.

That is when progress becomes visible.
