, in hiragana, or in katakana, is one of the Japanese kana, each of which represent one mora. The hiragana is written in one stroke; the katakana in two. Both represent the sound [ɾɯ] (About this soundlisten). The Ainu language uses a small katakana ㇽ to represent a final r sound after an u sound (ウㇽ ur).

The hiragana for ru (る) is made with one stroke, and its katakana form (ル) is made with two.

る (hiragana) begins with a horizontal stroke to the right, followed by a slightly longer, angular stroke going down and to the left. Finally, a curve and loop are added to the bottom that somewhat resembles the hiragana no (の). The character as a whole is visually similar to the hiragana for ro (ろ).

ル (katakana) is made by first making a curved stroke going down and to the left, and is followed by a stroke that first goes straight down, and then a curved line going up and to the right.
