With this tool you can attach Ruby hiragana, katakana or romaji to web pages or pieces of text.

  • You can choose hiragana, katakana or romaji for the Ruby.
  • You can choose to attach Ruby to kanji only, or to katakana and numbers too (全文 - all text).
  • The difference between the romaji for "読み" (Reading)" and "発音" (Pronunciation) is the long vowel sounds.

Ruby for "Reading" (left) and "Pronunciation" (right)

For those who find it difficult because the right side of the page gets covered, we introduce a method to fix that in our Special AddRuby Version .
