U+3031 "〱" Vertical Kana Repeat Mark Unicode Character

U+3031 "〱" Vertical Kana Repeat Mark is a typographic symbol used in Japanese writing to indicate that the preceding kana character should be repeated when text is oriented in a vertical column. This mark, known in Japanese as a "tate-yori" or vertical iteration mark, appears specifically in vertical writing systems and serves a similar function to its horizontal counterpart, the "々" (U+3005). It helps streamline text by avoiding the need to write the same character twice, and it is commonly encountered in classical literature, signage, and certain formal documents where vertical script is preferred.
