Rengoku
in Japanese
The default way to write Rengoku in Japanese is レンゴク — 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 Rengoku actually means at the root — From Japanese 煉獄 (rengoku), meaning 'purgatory' — a realm of refining fire where souls are purified. Finally a set of ateji, the playful tradition where the kanji match the sound and tell their own small story underneath.
