わ, in hiragana, or ワ in katakana, is one of the Japanese kana, which each represent one mora. It represents [wa] and has origins in the character 和. There is also a small ゎ/ヮ, that is used to write the morae /kwa/ and /gwa/ (くゎ, ぐゎ), which are obsolete in contemporary standard Japanese but still exist in the Ryukyuan languages. Katakana ワ is also sometimes written with dakuten, ヷ, to represent a /va/ sound in foreign words; however, most IMEs lack a convenient way to write this. It is far more common to represent the /va/ sound with the combination ヴァ.
