圓谷製作
After Tsuburaya's death, his eldest son Hajime was named president of Tsuburaya Productions and assembled a team to revise "Return of Ultraman". The first three shows were rebroadcast to temporarily appease fan demands. Shozo Uehara and TBS producer Yoji Hashimoto conceived the final concept of the series. Revisions were made to the new Ultraman's design, after feedback from licensees, to avoid similarities with the 1966 Ultraman. This included giving the new Ultraman gloves, boots, and pinstripes around the red areas. The new character was referred to as "New Ultraman" by fans and the name was used by Tsuburaya Productions for later appearances. The character was rebranded as "Ultraman Jack" in 1984 after Tsuburaya Productions held a contest for children to submit suggestions.
