Katakana Sokuon (ッ) — FAQ

What is the katakana small tsu (ッ)?

The small tsu is the sokuon (促音), a symbol that doubles the following consonant to create a short pause. It is written smaller than the normal katakana ツ. Example: ベッド (beddo) = "bed".

How do you pronounce the small ッ?

The ッ itself has no sound. You hold a brief silent beat before the next consonant, effectively doubling it. サッカー is pronounced sak-kā, not sa-tsu-kā.

How do you type the small ッ on a keyboard?

On a romaji IME, double the following consonant: type kk, pp, tt, ss and so on. For example type beddo to get ベッド, or sakka- for サッカー. To input a standalone ッ, type xtu or ltu.

What is the difference between ッ (katakana) and っ (hiragana)?

They work identically, both doubling the next consonant. ッ appears in katakana words (usually loanwords like バッグ baggu), while っ appears in hiragana words (like がっこう gakkō). Practice both with audio on Japanese 50 Sounds, a free hiragana & katakana learning tool.
