Renowned Japanese pop icon, Hideki Saijo, continues to inspire a growing fanbase, several years after his passing. Saijo earned a massive cult-like following in the Japanese Pop or "J-Pop" music industry during the 1970s and ’80s and has continued to impress even posthumously, a testament to his legacy. The recent surge in popularity is attributed to the rediscovery of his music by a new generation of fans.

In the context of Japanese society, Hideki Saijo is not just a singer but a cultural icon, a large part of the "Kayōkyoku" era of the Japanese music industry. His music and personality not only entertained but also comforted the Japanese public during their hard times. In Japan, there is a strong cultural value in preserving and appreciating the legacy of their idols.

In the US or EU, late music icons like Elvis Presley, The Beatles, and Michael Jackson continue to garner fans long after their passing, much like Saijo in Japan. The renewed interest in these artists often results from anniversary events, documentaries, or releases of previously unheard tracks, appealing to both older fans and drawing in new ones.
