Cyrillization of Japanese is the practice of transliterating the Japanese language into Cyrillic script, either to represent Japanese proper names or terms in Russian and the other languages written in Cyrillic, or as an aid to Japanese language learning in those languages. The following cyrillization system for Japanese is known as the Yevgeny Polivanov system. Note that it has its own spelling conventions and does not necessarily constitute a direct phonetic transcription of the pronunciation into the standard Russian usage of the Cyrillic alphabet.
