Understanding Diacritical Marks: Dakuten and Handakuten

Once you've mastered the 46 basic Hiragana and Katakana characters, you'll encounter diacritical marks that modify these characters to create additional sounds.

What are Diacritical Marks?

Diacritical marks are symbols added to characters to change their pronunciation. In Japanese, there are two main types:

• Dakuten (濁点): Two small strokes (゛) that make sounds "voiced"
• Handakuten (半濁点): A small circle (゜) used only with the H-row

Dakuten (゛)

Dakuten transforms voiceless consonants into their voiced counterparts:

K-row → G-row

• か (ka) → が (ga)
• き (ki) → ぎ (gi)
• く (ku) → ぐ (gu)
• け (ke) → げ (ge)
• こ (ko) → ご (go)

S-row → Z-row

• さ (sa) → ざ (za)
• し (shi) → じ (ji)
• す (su) → ず (zu)
• せ (se) → ぜ (ze)
• そ (so) → ぞ (zo)

T-row → D-row

• た (ta) → だ (da)
• ち (chi) → ぢ (ji) - Note: same sound as じ
• つ (tsu) → づ (zu) - Note: same sound as ず
• て (te) → で (de)
• と (to) → ど (do)

H-row → B-row

• は (ha) → ば (ba)
• ひ (hi) → び (bi)
• ふ (fu) → ぶ (bu)
• へ (he) → べ (be)
• ほ (ho) → ぼ (bo)

Handakuten (゜)

Handakuten is used only with the H-row to create P-sounds:

H-row → P-row

• は (ha) → ぱ (pa)
• ひ (hi) → ぴ (pi)
• ふ (fu) → ぷ (pu)
• へ (he) → ぺ (pe)
• ほ (ho) → ぽ (po)

Understanding Voiced vs Voiceless

Voiceless sounds (original characters):

• Produced without vocal cord vibration
• Examples: k, s, t, h, p

Voiced sounds (with dakuten):

• Produced with vocal cord vibration
• Examples: g, z, d, b

Think of the difference between "p" and "b" in English - same mouth position, but "b" uses your voice.

Common Words with Diacritical Marks

Here are some everyday words using these modified characters:

• がっこう (gakkō) - school
• じしょ (jisho) - dictionary
• でんわ (denwa) - telephone
• ばんごはん (bangohan) - dinner
• ぱん (pan) - bread

Learning Tips

1. Learn in Pairs: Study the base character and its modified version together

2. Practice Recognition: Use the Review mode with diacritical marks enabled

3. Focus on Differences: Notice how the dakuten/handakuten changes the sound

4. Common Patterns: Many words use these modified characters, so they're worth mastering

Special Notes

• じ (ji) and ぢ (ji): Both sound the same, but じ is more common
• ず (zu) and づ (zu): Both sound the same, but ず is more common
• Handakuten only with H-row: Unlike dakuten, handakuten is only used with は, ひ, ふ, へ, ほ

Practice Strategy

1. Start with one row at a time (e.g., K-row → G-row)

2. Practice writing both the base and modified characters

3. Use Quiz mode to test your recognition

4. Read simple texts that include these characters

Next Steps

After mastering diacritical marks, you can move on to:

• Contracted Sounds: Combination characters like きゃ, しゅ, ちょ
• Reading Practice: Start reading simple Japanese texts
• Vocabulary Building: Learn words that use these modified characters

Remember, these marks are essential for reading and writing Japanese. Take your time to master them!
