  • According to an interview with then-president of Tsuburaya Productions, Kazuo Tsuburaya, he stated that the decision to appoint Hiroshi Nagano as the main cast is to invoke the image of a youthful protagonist Daigo Madoka. His first name, Daigo, was devised by the series' producer, Hiroyasu Shibuya.
  • Daigo was meant to return in Ultraman Tiga & Ultraman Dyna: Warriors of the Star of Light movie and Ultraman Tiga Gaiden: Revival of the Ancient Giant but he was never made it due to his actor Hiroshi Nagano having trouble with scheduling conflict.

At that time Hiroshi actually suffered from hay fever, it depended on what was taken into play during the intention of the director who saw this.
