Dakuten, handakuten, and small kana: the details that change a sound

Practise Japanese diacritic marks and small kana as deliberate modifications rather than extra decoration.

A mark can change the consonant series

Dakuten, the two short marks used in forms such as が, じ, and だ, change the sound associated with a kana. Handakuten, the small circle used with the h-row, appears in forms such as ぱ.

Write the plain kana first, then add the mark with consistent size and spacing. The base form should remain recognisable after the modification.

Place the mark as part of the unit

A dakuten or handakuten is attached visually to its kana. If it floats too far away, it can look like punctuation or belong to the neighbouring character.

Use paired drills such as か/が, さ/ざ, and は/ぱ. Say both forms while writing so the visual change and the sound change reinforce each other.

Small kana are not miniature decoration

Small ゃ, ゅ, and ょ combine with an earlier kana to represent sounds such as きゃ and しゅ. Small っ marks a consonant pause and changes the rhythm of the following sound.

Practise the combination as one timing unit, but keep the small character visibly smaller and correctly positioned. Its size is part of the spelling information.

Use mixed sequences for recall

After isolated pairs, write a short sequence containing plain kana, dakuten, and one small kana combination. Shuffle the order so you are retrieving the modified forms instead of repeating a memorised table.

Finish by checking the mark count, size, and placement. In Japanese handwriting, a tiny misplaced mark can change what a reader sees, so precision is worth the extra pause.

Learn the base before the sound mark

Unicode describes voiced and semivoiced sound marks as modifications applied to base hiragana or katakana. Write the base kana, add the mark, and read the complete unit from the Japanese source. The mark is not a separate letter row to memorise without its base.

Keep the two layers visually close but conceptually separate while the hand is learning them.

Keep the mark attached at small size

Write one marked kana large enough to inspect and then at ordinary notebook size. Check whether the mark is still clearly associated with the base and whether it collides with the next unit. If it becomes ambiguous, slow down and repair spacing before adding speed.

A clean small mark is more useful than an oversized example that never transfers to a line.

Use small kana as deliberate units

Small kana can participate in sound combinations and special spelling conventions. Choose one sourced combination and practise the full unit, then compare it with the base kana at normal size. Do not enlarge the small form until it looks like a normal full-size syllable.

The Japanese source should decide the reading; the handwriting drill should preserve the size relationship.

Sources:

Practise the prolonged sound mark in context

The prolonged sound mark is used predominantly with katakana to indicate a lengthened vowel. Copy one sourced katakana word containing it, then write the same word from memory. Check the mark’s length and spacing without treating it as a full kana character.

Keep the source language context visible so a punctuation-like mark does not become an abstract decoration.

Sources:

End with a two-layer recall test

Write one base kana, one voiced or semivoiced form, and one small-kana or prolonged-mark combination from prompts. Read the results from the source and record whether the error was the base, the mark, size, or spacing.

A narrow contrast makes the next Japanese practice session easier to begin.

Sources:

Use a marked form in a real line

After practising a base kana and its voiced or semivoiced variant, place the marked form in a short sourced Japanese line. Read the line, cover it, and write it again while checking the base, mark, size, and spacing only after the memory attempt.

This keeps the sound mark connected to ordinary writing rather than leaving it as a detached symbol exercise.

Sources:

Retrieve the mark from sound

Prompt yourself with a sourced sound rather than a visible kana, write the base and mark, and compare the completed form only afterward.

This keeps the modification connected to reading and not just to a copied dot.
