The Sokuon: Small つ (Double Consonants)

Introduction

The sokuon, represented by a small つ (in hiragana) or ッ (in katakana), is a critical element in Japanese pronunciation. It does not represent a sound itself, but indicates a brief, one-beat pause or a "gemination" of the following consonant sound. Mastering this pause is essential for distinguishing between words and achieving natural-sounding speech. Its function is consistent across both hiragana and katakana scripts.

The Sokuon Character

Note: The romaji for the sokuon is represented by doubling the consonant letter that follows it (e.g., kk, tt, pp, ss).

Pronunciation Guide

The sokuon creates a momentary glottal stop or hold in the flow of speech. To pronounce it correctly:

1. Upon encountering the small つ/ッ, complete the sound of the previous syllable.
2. Hold the pronunciation for one full mora (beat) with your vocal cords tensed, as if you are about to say the next consonant but stop the air flow.
3. Release into the following consonant sound.

A common mistake is to pronounce it as a full "tsu" sound or to ignore it entirely, which can change the meaning of a word (e.g., 来た kita "came" vs. 切った kitta "cut").
