ルフィ
Your name
Luffy
in Japanese
The default way to write Luffy in Japanese is ルフィ — a phonetic katakana spelling that captures the sound and signals, instantly to a Japanese reader, that the name comes from elsewhere. But katakana is only one of three answers Japanese gives to a foreign name.
Below, we show all three. First the official katakana. Then a set of meaning kanji chosen to express what Luffy actually means at the root — The name 'Luffy' has no established etymological meaning as a traditional given name; it is most famously associated with Monkey D. Finally a set of ateji, the playful tradition where the kanji match the sound and tell their own small story underneath.
