Tokyo Pitch Accent Patterns: Heiban, Atamadaka, Nakadaka, Odaka

Core examples: 平板, 頭高, 中高, 尾高, さくら, あたま, こころ, はしが, にほんご.

The labels are only useful if you can hear them

Pitch-accent study often introduces four labels for Tokyo-type Japanese:

平板 頭高 中高 尾高

Learners memorize the labels and still cannot hear the difference. That is backwards.

The labels are useful only if they map to sound.

The key principle:

Pitch-accent labels are descriptions of pitch movement across morae and particles.

They are not abstract grammar categories. They are listening tools.

This article gives a practical explanation of the four major Tokyo pitch patterns and why particles matter.

The basic Tokyo-type idea: where does the pitch fall?

In Tokyo-type pitch accent, the major question is whether the pitch falls, and if so, after which mora. That fall is called downstep.

A word can be:

• unaccented: no fall within the word or before the following particle,
• accented on the first mora,
• accented somewhere in the middle,
• accented at the end, revealed by the following particle.

The traditional labels correspond to these patterns.

平板: heiban, no downstep

平板 means flat/unaccented in this system. A heiban word does not have a downstep within the word, and the following particle remains high.

Typical simplified pattern:

low → high → high → high

The important point is not that the whole word is literally flat. In many descriptions, the first mora may be low and the pitch rises, then stays high through the particle.

Example pattern:

さくらが low-high-high-high

The particle が stays high.

Learner test:

If the particle stays high, the word may be heiban.

頭高: atamadaka, fall after the first mora

頭高 means head-high. The word starts high and falls immediately after the first mora.

Pattern:

high → low → low

With particle:

high → low → low + low particle

This pattern is important because it makes the first mora prominent in pitch, but not by English stress. It is high pitch followed by a drop.

A common textbook example category includes words where the first mora is accented.

Learner test:

If the word starts high and drops after the first mora, it is atamadaka.

中高: nakadaka, fall in the middle

中高 means middle-high. The pitch rises and then falls somewhere before the end of the word.

Pattern for a multi-mora word:

low → high → high → drop → low

The downstep occurs inside the word.

A word like あたま is often used in beginner explanations of pitch patterns, depending on the accent reference and dialect target. The important learner task is to hear the internal fall.

Learner test:

If the pitch falls before the word ends, not after the first mora, the word is nakadaka.

尾高: odaka, fall after the final mora

尾高 means tail-high. The word itself may sound similar to heiban in isolation because the fall happens after the final mora, when a particle follows.

This is why particles matter.

Pattern without particle may sound like:

low → high → high

With particle:

low → high → high → low particle

The particle drops.

Learner test:

If the word seems high through the end but the following particle drops, it is odaka.

This is the pattern that convinces learners to practice words with particles.

Why isolated words are not enough

Some accent patterns are hard to distinguish when words are spoken alone. Heiban and odaka can be especially confusing because the distinction may appear when a particle follows.

Compare:

はし

By itself, the pitch information may be insufficient for a learner. In a phrase:

はしが

the particle helps reveal the pattern.

This is why pitch-accent dictionaries and teachers often use particle tests. A Japanese word is not fully understood as a pitch object until you hear it in a phrase.

Accent numbers

Many dictionaries use numbers to mark accent. The number often indicates after which mora the downstep occurs.

A simplified way to think:

• 0: heiban, no downstep before particle.
• 1: downstep after first mora.
• 2: downstep after second mora.
• 3: downstep after third mora.
• etc.

For a word with final accent, the number may equal the word’s mora count, and the drop appears before the particle.

Labels and numbers are different notation systems for the same practical issue: where the pitch falls.

Mora count matters

Pitch accent works over morae, not English syllables. If you miscount long vowels, small っ, ん, or yōon, your pitch pattern will be wrong.

Example:

にほんご

Mora count:

に・ほ・ん・ご

Four morae.

A pitch pattern must be attached to these units. If you think in English syllables, you will not place pitch correctly.

Common learner mistakes

Mistake 1: Treating high pitch as loud stress

Do not punch the accented mora like English stress. Pitch is height, not force.

Mistake 2: Memorizing labels without audio

Labels are useless without listening.

Mistake 3: Ignoring particles

Particles reveal patterns.

Mistake 4: Miscounting morae

Long vowels, ん, っ, and yōon matter.

Mistake 5: Thinking Tokyo equals all Japanese

Tokyo patterns are a target variety, not the entire language.

Example bank walkthrough

平板

Unaccented pattern with no downstep before the following particle.

Learner action: listen for particle staying high.

頭高

High at the beginning, fall after first mora.

Learner action: avoid turning it into English stress.

中高

Downstep occurs inside the word.

Learner action: identify the mora after which pitch falls.

尾高

Fall occurs after the final mora, visible before particle.

Learner action: always test with a particle.

さくら

Common example used in pitch discussions.

Learner action: practice with が and compare dictionary pattern.

あたま

Useful for hearing internal pitch movement.

Learner action: map pitch to morae.

こころ

Another common multi-mora pitch-practice word.

Learner action: practice slowly with pitch contour.

はしが

Particle test phrase for はし minimal sets.

Learner action: compare meanings and contours.

にほんご

High-frequency word where mora count and pitch practice matter.

Learner action: learn phrase-level pronunciation, not only isolated word.

Pattern workflow

For any word:

1. Write kana.
2. Count morae.
3. Check accent number or pattern.
4. Add が or another particle.
5. Mark high/low sequence.
6. Listen to native audio.
7. Hum contour.
8. Speak in phrase.
9. Record and compare.

A strong tool for this article would let users select word length and accent type.

Suggested functions:

1. Pattern labels: 平板, 頭高, 中高, 尾高.
2. Accent-number display: 0, 1, 2, 3, etc.
3. Particle toggle: Add が and show change.
4. Mora blocks: Attach pitch to each mora.
5. Audio playback: Isolated word and phrase.
6. Minimal-pair mode: はしが, あめが.
7. Recording mode: Compare learner contour.
8. Dialect caution: Tokyo target with regional variation note.

Final rule

Heiban, atamadaka, nakadaka, and odaka are not vocabulary words to memorize. They are ways to hear pitch movement.

Count morae. Add a particle. Find the downstep. Listen before labeling.

Pitch-accent terminology becomes useful only when your ear can follow the contour.
