Ojarumaru is a long-running Japanese children's anime broadcast by NHK, following a young prince from the Heian era who comes to live in modern Japan. It first aired in 1998 and has remained a familiar part of Japanese television for generations of viewers. Because the series is so widely recognised in Japan, short opening clips are often shared online as nostalgic references, especially in anime edits, reaction videos and fan compilations that play on its gentle humour and distinctive old-meets-new premise.
