Dakuten and Handakuten: The Japanese Accent Marks That Change Everything

You have spent hours drilling hiragana and katakana. You can read か, さ, た, and は without hesitation. Then you open a Japanese text and encounter が, ざ, だ, and ぱ — the same characters, but with tiny marks attached. Suddenly, nothing looks familiar.

Do not panic. Those tiny marks — called dakuten (濁点・だくてん) and handakuten (半濁点・はんだくてん) — are one of the most logical, rule-based parts of the Japanese writing system. Once you understand them, you will have unlocked an extra 50+ characters without learning a single new symbol from scratch.

This guide walks you through everything: what the marks mean, how they change sounds, how to write and type them, and how to avoid the most common mistakes English speakers make.

What Is Dakuten? Understanding Voiced Sounds

The dakuten (゛) looks like a small quotation mark — two short diagonal strokes placed at the top-right corner of a character. In Japanese, it is sometimes called ten-ten (てんてん) in informal speech, which literally means “dot dot.”

What does it actually do to a sound? It converts an unvoiced consonant into a voiced consonant.

Here is a quick explanation of voicing for English speakers: put your fingers lightly on your throat and say “s.” You should feel almost no vibration. Now say “z.” Feel that buzz? That vibration is your vocal cords activating — that is what “voiced” means. Dakuten triggers exactly the same shift in Japanese consonants.

Yuka

So dakuten is like a voicing switch? You flip it on and the sound starts vibrating?

Rei

Exactly! Think of it this way: か (ka) has a hard, unvoiced k sound. Add dakuten and you get が (ga) — the same mouth shape, but your throat vibrates. The mark tells your vocal cords: turn on!

The Four Rows Affected by Dakuten

Dakuten only works on four specific rows of the Japanese syllabary. Here are all the transformations, with both hiragana and katakana:

What Is Handakuten? The Circle That Creates P-sounds

The handakuten (゜) is a small open circle placed at the top-right corner of a character. The word han (半) means “half,” so handakuten literally means “half-voiced mark” — it sits between a fully unvoiced and a fully voiced sound.

The handakuten is more limited than the dakuten: it only applies to the h-row (は行), transforming those sounds into p-sounds. The p-sound is called semi-voiced because it uses lip closure (like b) but without the vocal cord vibration.

Rei

Wait — why does the h-row become p? That seems random. Shouldn’t it become something closer to h?

Yuka

It is actually rooted in historical linguistics! Old Japanese had a p-sound (like ぱ) that gradually softened into f and then h over time. The handakuten essentially revives that ancient p-sound. That is why は, ひ, ふ, へ, ほ sit between ば (b-sound) and ぱ (p-sound) in the voicing system.

H-row → P-row (は行 → ぱ行)

Quick tip for recognizing p-sounds: In katakana, p-sounds appear constantly in loanwords. Think ピアノ (piano), プール (pool), パソコン (personal computer), ポケット (pocket). If you see a katakana character with a small circle, it is always a p-sound.

How to Write Dakuten and Handakuten

Stroke Order and Handwriting

When writing by hand, both marks are added after the base character is complete. Treat them as separate strokes.

  • Dakuten (゛): Write the base character first. Then add two short diagonal strokes at the top-right corner, going from upper-left to lower-right. The strokes should be small — roughly a quarter of the character’s height. Think of writing a tiny quotation mark.
  • Handakuten (゜): Write the base character first. Then draw a small open circle at the top-right corner in a single counterclockwise stroke. Keep it small and distinct — it should look like a degree symbol (°), not a full-sized circle.

Common Handwriting Mistakes

  • Dakuten too large: If your ten-ten strokes are too long or bold, the character becomes hard to read at a glance. Keep them small and light.
  • Handakuten looks like dakuten: A closed circle (○) drawn with two strokes can look like a sloppy dakuten. Practice making the handakuten a clean, round open loop.
  • Wrong position: Both marks always go in the top-right corner. Placing them on the left or bottom is a common beginner error.
  • Forgetting the mark entirely: In fast handwriting, dakuten are easy to skip. Native Japanese writers never omit them — always double-check your work.

Typing Dakuten and Handakuten on a Keyboard

The good news: you never need to add dakuten or handakuten manually when typing. Japanese input methods (IME) handle this automatically. Just type the romanization and select the correct character.

On a smartphone using the flick input (フリック入力) method, voiced characters are accessed by swiping left on the base character. Many learners find flick input for voiced sounds very intuitive once they know the base characters well.

Common Pronunciation Mistakes English Speakers Make

Yuka

I keep mixing up じ and ぢ. They sound the same to me. Is there actually a difference?

Rei

You are not wrong — in modern standard Japanese, じ and ぢ are pronounced identically. The same goes for ず and づ. The distinction is about spelling, not sound. Knowing when to write which one is a vocabulary question, not a pronunciation one!

The じ vs ぢ and ず vs づ Problem

This is one of the most frequently asked questions about dakuten. Here is the rule in plain terms:

SoundStandard spellingぢ/づ is used when…Example
jiThe word is a compound where the base word has ちはなぢ (鼻血, nosebleed) ← 血 (chi)
zuThe word is a compound where the base word has つつづく (続く, to continue) ← 続 (tsu-)

In all other cases, write じ for “ji” and ず for “zu.” As a beginner, do not stress about this distinction. Learn words as vocabulary items and the correct spelling will come naturally over time.

Mistake 1 — Over-voicing the G-sound

English speakers tend to pronounce が as a strong, hard “ga” — like the “g” in “gap.” In Japanese, the g-sound is slightly softer. In the middle of a word, it can even become a nasal sound similar to the “ng” in “sing.” This is called bigo (鼻濁音) and appears in certain dialects and formal speech. For now, just avoid making the g-sound too explosive.

Mistake 2 — Treating ざ, じ, ず, ぜ, ぞ as English Z-sounds

Japanese ざ is not the same as the English “za” in “pizza.” The Japanese z-sound is produced with the tongue touching the gum ridge, similar to “dz” — a short, stopped sound before the vowel. So ざ sounds closer to “dza” than the smooth English “z.” This is subtle, and native speakers will still understand you if you use an English z, but training your ear and mouth to hear the difference will help your pronunciation accuracy.

Mistake 3 — Forgetting to Read the Mark At All

When reading quickly, beginners sometimes skim past the dakuten and read the unvoiced version of the character. This can completely change meaning. For example:

  • きって (切手, stamp) becomes completely different if read as ぎって — confusion like this is easy when reading fast
  • さくら (桜, cherry blossom) vs ざくら — ざくら appears in compound words (e.g., よざくら, night cherry blossoms), so reading the mark correctly matters

Train yourself to scan the top-right corner of every character as a habit.

Minimal Pairs Practice: How Dakuten Changes Meaning

The clearest way to see why dakuten matters is through minimal pairs — word pairs that differ only in one sound. Study these carefully and practice saying them aloud:

Word AReadingMeaningWord BReadingMeaning
かきkakioyster / persimmonがきgakibrat (child, informal)
かみkamigod / hair / paperがみgamipaper (suffix in compound words, e.g. 折り紙)
さかsakaslopeざかzaka(suffix in place names, e.g. 坂 in 大坂)
しろshirowhite / castleじろjiroa person’s name (次郎)
すきsukito like / gapずきzukithrob (as in headache)
たなtanashelfだなdanaright? / isn’t it? (sentence-ending)
てらteratempleでらderatemple (suffix in compound words)
はなhananose / flowerばなbana(suffix in words like ことばな)
はこhakoboxばこbakobox (suffix in compound words, e.g. 本箱)
ほしhoshistar / dried (food)ぼしboshihat (帽子, boshi)
はくhakuto wear (below waist) / to vomitばくbakutapir / explosion
かくkakuto write / eachがくgakumusic / learning / amount of money

Practice tip: Cover the right half of the table and try to recall the voiced version of each word. Then switch and recall the unvoiced. Doing this out loud — not just visually — builds the muscle memory your mouth needs.

Reading Practice: A Short Paragraph

Read the following short paragraph aloud. Pay close attention to every dakuten and handakuten. A vocabulary guide follows below.

Decision Flowchart: Identifying Voiced vs Unvoiced When Reading

When you encounter an unfamiliar character, use this mental checklist:

You see a hiragana or katakana character
        |
        v
Does it have a mark in the top-right corner?
        |
    YES / \ NO
       /   \
      v     v
Is the mark    Read the base sound
two strokes    as-is (unvoiced).
or a circle?   No change needed.
      |
  Two strokes = Dakuten (゛)
      |
      v
Which row is the base character from?
  か-row? --> Read as G-sound (が, ぎ, ぐ, げ, ご)
  さ-row? --> Read as Z-sound (ざ, じ, ず, ぜ, ぞ)
  た-row? --> Read as D-sound (だ, ぢ, づ, で, ど)
  は-row? --> Read as B-sound (ば, び, ぶ, べ, ぼ)
      |
  Circle = Handakuten (゜)
      |
      v
Base character is always from は-row
  --> Read as P-sound (ぱ, ぴ, ぷ, ぺ, ぽ)

Quick Quiz

Test yourself! Read each character or word and write down the romanization and meaning (for vocabulary words). Answers are below.

  1. What sound does ぞ represent?
  2. What sound does ぴ represent?
  3. Which mark would you add to き to make ぎ?
  4. Read this word: ぼうし. What does it mean? (Hint: it is clothing for your head.)
  5. What is the difference in meaning between すき and ずき?
  6. True or false: ぢ and じ are pronounced differently in modern standard Japanese.
  7. Read this word: でんわ. What does it mean?
  8. Add the correct mark to change ふ into ぷ. What mark is it, and what is the resulting sound?

Quiz Answers

  1. zo (the z-sound equivalent of そ/so)
  2. pi (the p-sound equivalent of ひ/hi)
  3. Dakuten (゛) — the two small diagonal strokes
  4. ぼうし (帽子) — a hat or cap; reading: bou-shi
  5. すき (suki) means “to like” or “a gap”; ずき (zuki) means a throbbing sensation (like a headache)
  6. False — in modern standard Japanese, ぢ and じ are both pronounced “ji.” The difference is orthographic (spelling), not phonetic.
  7. でんわ (電話, denwa) — telephone
  8. Handakuten (゜) — the small circle. The result is ぷ, pronounced “pu.”
