'''Wave dash''' ({{unichar|301C|WAVE DASH}}) is a character represented in [[Japanese language and computers#Character encodings|Japanese character encoding]] mainly used as a [[dash]] and [[chōonpu]]. The wave dash is similar to, but not the same as, the [[tilde]] character ({{unichar|FF5E|FULLWIDTH TILDE|nlink=Halfwidth and fullwidth forms}}), which is often used interchangeably with it.

The vertical wave dash ([[File:Wave DashV.svg|16px]]) is not currently included in Unicode, but there is a similar symbol available called the wavy line ({{unichar|2307|WAVY LINE}}). It is created by rotating right (clockwise) the wavy dash symbol ({{unichar|3030|WAVY DASH}}) to form a vertical wave-like pattern.

Wave dash is also written in [[Horizontal and vertical writing in East Asian scripts|vertical text layout]]. Vertical wave dash is the vertical form by rotation and flip in Unicode and JIS C 6226.<ref name="Lunde1999">{{cite book|author=Ken Lunde|title=CJKV Information Processing: Chinese, Japanese, Korean & Vietnamese Computing|url=https://books.google.com/books?id=Cn7jnk9WwZEC&pg=PA346|year=1999|publisher=O'Reilly Media |isbn=978-1-56592-224-2|pages=345–346, 348}}</ref><ref>{{Citation|url=http://unicode.org/reports/tr50/|title=Unicode Vertical Text Layout|website=Unicode |at=Table 4.
