URL Slug Generator (Japanese to Romaji, Hyphenated)

Enter an article title or product name and get a URL-safe slug: hiragana and katakana become romaji, symbols are removed, and words are joined with hyphens. You can cap the length and convert many lines at once. For variable-name styles, use the Text Case Converter; for plain kana and romaji conversion, try the Romaji ⇔ Hiragana Converter.

Notes

  • Kanji cannot be romanized because their readings depend on context. "Remove" drops them; "Keep as is" leaves them in, which turns into a long percent-encoded string in a URL. For titles with kanji, rewrite them in English or romaji first.
  • Kana is converted with Hepburn romanization. Long vowel marks and the apostrophe after n are omitted, and particles are spelled as written (ha, o).
  • Full-width letters and digits and half-width katakana are normalized first. Characters other than letters, digits and kanji, such as Hangul or Cyrillic, are treated as separators and removed.
  • Slugs are lowercase, and any symbol other than letters, digits and the separator is removed.

FAQ

Can it turn kanji into romaji?

No. Kanji readings depend on context, so the tool cannot convert them. Choose "Remove" to drop kanji or "Keep as is" to leave them. Only hiragana and katakana become romaji, so rewrite kanji titles in English or romaji first.

Should a slug use hyphens or underscores?

Hyphens are the usual choice for SEO, and Google treats them as word separators. Pick hyphens unless you have a specific reason not to.

How long should a slug be?

There is no fixed limit, but short and descriptive, around 50 to 60 characters, is common. With a max length set, the tool can cut at the previous separator rather than mid-word.

How is this different from kebab-case in the case converter?

The case converter only splits identifiers into words and rejoins them. This tool also romanizes Japanese kana, strips symbols and applies a length limit, so the result is ready to use in a URL.
