Romaji Converter: Convert Japanese Hiragana and Katakana to Romaji
Key Takeaways
- Romaji is the romanization of Japanese text using Latin letters, essential for non-native speakers to read and pronounce Japanese words.
- There are multiple romanization systems — Hepburn (most common internationally), Kunrei-shiki (taught in Japanese schools), and Nihon-shiki (systematic).
- Converting between hiragana/katakana and romaji is fundamental for Japanese language learners, travelers, and anyone working with Japanese text.
Japanese uses three writing systems: hiragana, katakana, and kanji. For people who cannot read these scripts, romaji — the representation of Japanese sounds using Latin alphabet letters — is the essential bridge. Whether you are a Japanese language student practicing reading, a traveler trying to pronounce place names, or a developer building multilingual applications, a romaji converter instantly translates Japanese script into readable, pronounceable Latin characters.
Japanese has 46 basic hiragana and 46 basic katakana characters, each mapping to a specific romaji syllable

Tips for Romaji Conversion
Hepburn romanization is the international standard used on passports, road signs, and in most textbooks outside Japan.
Long vowels matter in Japanese: different vowel combinations have distinct pronunciations. Pay attention to vowel length markers.
Katakana is used primarily for foreign loanwords. Converting katakana to romaji often reveals the original English word.
Kanji (Chinese characters) cannot be converted to romaji by simple character mapping — they require dictionary lookup for correct pronunciation readings.
All text conversion is performed locally in your browser. No Japanese text is transmitted to any external server, ensuring your content remains private.
