In late 2004, it was announced that Shigeki Hosokawa would be the lead in the then upcoming season of the long running Kamen Rider franchise, Kamen Rider Hibiki. He drew fans from both the target demographic of children and house wives alike. His role as Hibiki garnered many good reviews from Japanese critics. After Kamen Rider Hibiki finished airing, he then landed the role of Taira no Shigehira in the Samurai Drama, Yoshitsune. Both Kamen Rider Hibiki and Yoshitsune aired in the 8:00 time slot, AM and PM respectively. Because both shows aired in different 8 o'clock timeslots, he has been given the nickname "The 8 o'clock man" in Japan. Hosokawa's next major role was that of the ill-fated F.B.I. agent, Raye Iwamatsu, in the live action adaptations of the Death Note manga. He then went on to play the father character in the TV movie, Kaigo Etoile (The Nursing Care Star) which will start its Japanese airing on September 18, 2006. He played the father of the main character. His role is that of an aging and divorced father who has developed dementia.
