| Footnote: | These Man'yōgana originally represented morae with one of two different vowel sounds, which merged in later pronunciation. |
そ, in hiragana, or ソ, in katakana, is one of the Japanese kana, each of which represents one mora. Both represent pronounced as /[so]/. The version of this character used by computer fonts does not match the handwritten form that most native Japanese writers use. The native way is shown here as the alternative form.
