Aizen

in Japanese

The default way to write Aizen in Japanese is アイゼン — 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 Aizen actually means at the root — The name 'Aizen' has multiple possible origins. Finally a set of ateji, the playful tradition where the kanji match the sound and tell their own small story underneath.
