How much Japanese should you understand when listening?

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 learners ask this question, even if they don’t say it out loud:

“How much Japanese am I supposed to understand?”

They worry when they miss words.
They feel unsure when meaning feels vague.
And they often assume that low understanding means low progress.

But listening does not work that way.

Understanding is not a percentage

It’s tempting to think in numbers.

  • 80% understanding = good

  • 50% understanding = not enough

  • 20% understanding = failure

But your brain does not learn languages by percentages.

Real listening is not about how many words you understand.
It’s about whether you can stay with the meaning.

What actually matters when listening

Instead of asking “How much did I understand?”, try noticing this:

  • Could you follow the situation?

  • Did you know who was speaking?

  • Did you feel the mood or intention?

  • Did the story make sense, even roughly?

If the answer to some of these is yes, then your listening was successful.

Even if many words were unclear.

Some days feel better than others

Your understanding will change from day to day.

  • Tired days feel harder

  • Busy days feel noisy

  • Calm days feel clearer

This does not mean your Japanese is unstable.
It means your brain is human.

On days when understanding feels low, listening still matters.
Your brain is still collecting sound, rhythm, and patterns.

Progress does not disappear just because a day feels difficult.

A practical guideline

Here is a gentle way to think about it:

If you can follow the general flow, that is enough.

You do not need:

  • Perfect clarity

  • Full sentences

  • Grammar awareness

You only need:

  • A sense of “what is happening”

  • A feeling that you are not completely lost

If you feel completely lost most of the time, the input may be too difficult for now.
That is not failure—it is feedback.

Why “almost understanding” is powerful

When something feels almost understandable, your brain stays engaged.

  • It listens instead of translating

  • It guesses instead of stopping

  • It connects instead of analyzing

This is where listening grows.

Clear understanding often comes after repeated exposure,
not during the first listen.

Trust the process

You do not need to measure your understanding.
You do not need to test yourself.

If Japanese feels a little more familiar than before,
your listening is working.

That quiet familiarity is what eventually turns into confidence.
