ジェイソン
Your name
Jason
in Japanese
The default way to write Jason in Japanese is ジェイソン — 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 Jason actually means at the root — From the Greek name Iason (Ἰάσων), meaning 'healer' or 'one who heals,' derived from the verb iasthai (to heal). Finally a set of ateji, the playful tradition where the kanji match the sound and tell their own small story underneath.

Not sure which form to use?
Katakana, meaning kanji, and ateji each belong to a different part of Japanese life — official paperwork, calligraphy and gifts, signatures and wordplay. Our full guide walks through when to reach for each one.
