の, in hiragana, and ノ, in katakana, are Japanese kana, both representing one mora. In the gojūon system of ordering of Japanese syllables, it occupies the 25th position, between ね (ne) and は (ha). It occupies the 26th position in the iroha ordering. Both represent the sound. The katakana form is written similar to the Kangxi radical 丿, radical 4.

Katakana is a Japanese syllabary, one component of the Japanese writing system along with hiragana, kanji and in some cases the Latin script.
