Fullwidth Hyphen-Minus

It is a one-cell CJK form of the ordinary hyphen-minus. Fullwidth marks occupy one cell in grid-based East Asian text. This form comes from older mixed-width Chinese, Japanese, and Korean encodings: widening a hyphen aligned it with full-cell characters and made text conversion faithful. Its width adds no new punctuation job; Japanese also calls it a zenkaku hyphen.

Which dash-like mark should I use?

Choose the punctuation job first; width comes second. This mark can act as a hyphen or minus; its shape alone does not decide. Use ー for a Japanese long vowel and − for mathematical subtraction. Japanese style guidance generally avoids hyphens in prose, using ASCII - in addresses and phone numbers. Chinese punctuation gives joining marks and two-em dashes different jobs. As of 2026, －－ is a documented Chinese online fallback for a two-em dash; use —— or ⸺ when exact punctuation matters.

How do I type the fullwidth form?

Choose the fullwidth candidate in a Japanese input method. A Japanese input method editor (IME) converts keystrokes into Japanese text. Its hyphen key may yield ー first; conversion can offer a fullwidth or zenkaku candidate. Phone symbol menus vary. In 2025, a WebKit report described this among Japanese IME minus-like outputs and differing numeric-field treatment. Convert it to ASCII - before validating machine-readable numbers.
