O (kana)

お and オ originate, via man'yōgana, from the kanji 於.

Scaled-down versions of the kana (ぉ, ォ) are used to express morae foreign to the Japanese language, such as フォ (fo).

The hiragana お is made with three strokes:

1. A horizontal line from left to right.
2. A stroke consisting of a vertical line, a small diagonal line going upwards and to the left, and an open curve heading right and downwards.
3. A small curved stroke on the right.

The katakana オ is made with three strokes:

1. At the top, a horizontal stroke from left to right.
2. A downward vertical stroke cutting through the first stroke, with a small hook at the end facing left.
3. At the intersection of the first two strokes, a diagonal line going downwards and to the left.

{{asterisk}} When lengthening "-o" morae in Japanese braille, a chōon is always used, as in standard katakana usage instead of adding an お / オ.
