==Trivia==
*Koichi Yamadera's favorite Ultra Warriors are Ultraman, Ultraseven and Ultraman Ace.
*Discounting Jackal vs. Ultraman, Sadis in Orb The Movie is his first role in the Ultraman Series since Lloyd Wilder in Ultraman Great. Because of this, he was excited to return to the franchise and be casted as Sadis. Although initially nervous about this role, the director encouraged ad-libs in his role.
*He is known for his versatile range, as protagonists, antagonists, and even to the point of voicing as a female.
*Although he did not voice Zetton in Shin Ultraman, Yamadera posted his own impression of the monster's noises on Twitter.https://twitter.com/yamachanoha/status/1542841137765171200https://twitter.com/yamachanoha/status/1543584868768305158
