ジャスティン
Your name
Justin
in Japanese
The default way to write Justin in Japanese is ジャスティン — 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 Justin actually means at the root — From the Latin name Justinus, derived from Justus, meaning 'just', 'fair', 'righteous', or 'upright'. Finally a set of ateji, the playful tradition where the kanji match the sound and tell their own small story underneath.
