Aizawa
in Japanese
The default way to write Aizawa in Japanese is アイザワ — 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 Aizawa actually means at the root — Aizawa (相沢/相澤) is a Japanese surname meaning 'mutual marsh' or 'meeting swamp,' combining 相 (ai, 'mutual/together') with 沢 (sawa, 'marsh/wetland'). Finally a set of ateji, the playful tradition where the kanji match the sound and tell their own small story underneath.
