Turn hiragana into katakana for a furigana field
Japanese forms ask for your name's reading in a specific script — usually katakana. Here is the quick conversion, plus what to check before pasting.

The job
A registration form wants your name twice: kanji for the name itself, and a furigana field for how it is read. Most sites ask for that reading in katakana, some in hiragana — pasting the wrong script fails validation or lands in the database mislabeled.
How to do it
Paste the reading into the converter, pick the direction, convert, and copy the result back into the field. Kanji, letters, and the long-vowel mark ー pass through unchanged, so a mixed string is safe.
- The katakana direction also converts the iteration marks ゝゞ to ヽヾ — useful for names like こころ → ココロ and older spellings.
- Romaji input does not become kana — use the romaji converter first if your source is in letters.
Worked example
やまだ たろう pasted into the hiragana→katakana direction returns ヤマダ タロウ — the space between given and family name stays, which most furigana fields want.
Limits
Only full-width kana are converted; half-width katakana (ｶﾀｶﾅ) stays untouched — convert it to full-width first if a field rejects it. The tool does not know how your name is pronounced: it converts the reading you type, so start from the correct hiragana.
