The
No.1 Sentai Gozyuger trademark was registered by Toei Company on October 24, 2024, and published on November 1, 2024.
Gozyuger was officially announced on December 25, 2024. A production announcement conference introducing the main cast and characters and the artists for the show's opening and ending theme songs was held on January 24, 2025 and streamed on Toei Tokusatsu Fan Club and YouTube on January 26, 2025. According to producer Daigo Matsuura, while
Gozyuger does include past Sentai heroes as part of anniversary celebration series, they instead are portrayed as Universe Warriors; fellow rivals to the titular team with different characters behind the suit. This was also done to introduce preceding heroes to children and newcomers alike without the need of bringing back past actors, as Matsuura draws comparison to the Ultra Monster Gomora from
Ultraman being popular amongst today's children for its recurring appearances in modern day installments of
Ultraman series despite being portrayed by different suit actors.
