Common Japanese Speaking Mistakes and How to Fix Them (Real Student Feedback)
Common Japanese Speaking Mistakes and How to Fix Them (Real Student Feedback)
Have you ever wondered what your Japanese actually sounds like to a native speaker? You might feel like you're saying everything correctly, but subtle errors in sounds, rhythm, and pitch can make your speech harder to follow — even when your grammar is perfect.
In this feedback session, fumi analyzes a real recording sent in by Aria, a French learner of Japanese. The overall impression? Genuinely impressive — every word was understandable, and the vowels were clean. But there were four specific areas that held the speech back from sounding truly natural. Whether you're a beginner or an intermediate learner, these are exactly the kinds of details that separate "technically correct" Japanese from natural, fluent-sounding Japanese.
Let's break down each of the four feedback points so you can start applying them to your own speech.
1. Pronunciation: Getting し and ち Right
Two sounds that often trip up learners — especially those whose native language is French, Spanish, or English — are し (shi) and ち (chi). In Aria's recording, these were occasionally coming out closer to "ssi" or "tchi," with a slightly different mouth shape than Japanese requires.
The secret is in your mouth shape
In Japanese, the い (i) row of sounds — い、き、し、ち、に (i, ki, shi, chi, ni) — should all be produced with essentially the same mouth position: lips slightly spread, mouth relatively flat. The shape doesn't change dramatically from sound to sound.
Try saying each of these in sequence:
い・き・し・ち・に
i – ki – shi – chi – ni
If you do this in front of a mirror, your mouth shape should stay fairly consistent throughout. If you notice your lips rounding or your jaw moving significantly, that's a sign you're overworking the sounds.
2. こんにちは Is Longer Than You Think
This one surprises a lot of learners: こんにちは (konnichiwa) is frequently said too short.
In Japanese, timing is everything. The language is mora-timed, meaning each unit of sound (mora) takes roughly the same amount of time. こんにちは has 5 morae:
ko – n – ni – chi – wa
When learners rush this greeting, it tends to collapse into something closer to:
~~konnichiwa~~ → sounds like 今日は (kyō wa) — "Today is…"
That's because the full こんにちは actually comes from the phrase 今日は (konnichi wa), and when you shorten it, it sounds less like a greeting and more like an unfinished sentence.
Practical tip: Say each part of こんにちは clearly and give the final わ (wa) its full weight. Don't swallow the ending.
3. Intonation: The Good News
Aria's intonation — the natural rise and fall of the voice across a sentence — was very natural. Phrases like お元気ですかお (o-genki desu ka, "How have you been?") had a smooth, descending melody that sounded genuinely Japanese.
This is worth highlighting because intonation is one of the hardest things to teach, and it often comes from extensive listening. If your intonation already sounds natural, that's a sign your listening practice is working. Keep it up.
4. Pitch Accent: The Direction That Matters Most
Pitch accent is where things get interesting. Japanese pitch accent isn't just about whether you accent a word — it's about the direction of that accent.
In Aria's recording, the word 私は (watashi wa, "I / as for me") was being said with a falling pitch when it should actually rise:
私↑は — the pitch goes UP on わ (wa)
Fumi made an important observation here that's worth memorizing as a general rule:
The asymmetry of pitch accent errors
Saying a rising word with a falling pitch sounds very wrong.
Saying a falling word without the drop sounds much less wrong.
In other words, the two types of pitch accent errors are not equal. If you accidentally flatten a word that should fall, most listeners won't be too bothered. But if you drop the pitch on a word that should stay high or rise — like 私は — it sounds noticeably off.
What to do when you're unsure
If you genuinely don't know the pitch accent of a word, default to the flat (平板型, heiban-gata) pattern — say it with no pitch drop at all. This is the safest choice because:
平板型 (flat pattern) is statistically the most common pitch pattern for nouns in Japanese
Keeping the pitch level is less jarring than accidentally dropping it in the wrong place
This isn't a perfect solution, but it's a smart strategy while you build your pitch accent knowledge.
5. Pausing: Where You Breathe Changes Everything
The final feedback point was about pausing — where you break up your speech. Unexpected pauses in the middle of words or phrases can make even grammatically perfect Japanese sound choppy and unnatural.
In Aria's recording, the phrase:
すごく忙しかったんです (sugoku isogashikatta n desu — "I was really busy")
was being broken up awkwardly, almost like:
すごくいい…忙しかったんです
The solution isn't to eliminate pausing — pausing is natural and necessary. The key is where you pause:
Pause after particles (は, が, を, に, etc.) or at the end of clauses
Never pause in the middle of a word
If a word is difficult to say fluently (like 忙しかった), pause before it to give yourself a moment to prepare, then say the whole word smoothly
すごく… ｜ 忙しかったんです ✓
Pausing at the right boundary gives your speech a natural, deliberate quality rather than a hesitant, fragmented one.
Conclusion
Aria's Japanese was genuinely impressive — clear vowels, natural intonation, and everything understandable. But the four areas of feedback here apply to almost every learner at the intermediate level:
し and ち need a flatter, more consistent mouth shape across the い-row sounds
こんにちは deserves its full five morae — don't rush the ending
Pitch accent errors aren't equal — dropping what should rise is more disruptive than failing to drop what should fall; when in doubt, go flat
Pause at phrase boundaries, not in the middle of words — even if it means slowing down
The encouraging takeaway: if your vowels are clean and your intonation is natural, you're already most of the way there. These finer points are what take your Japanese from "correct" to "natural."
Start Today: One Thing to Practice Right Now
Pick three words you use every day in Japanese — ideally nouns like 日本語 (nihongo), 先生 (sensei), or your own name in Japanese. Look up their pitch accent patterns (apps like Migii or the Takoboto dictionary show pitch accent diagrams). Then practice saying each word both ways: once with the correct pitch, and once with the wrong pitch. Training your ear to hear the difference is the first step to producing the right pattern automatically.
