Despite Ultraman Ace proving to be fairly popular throughout its run, the show was not without its problems behind the scenes - so much so that some at broadcaster TBS even suggested putting the franchise on hiatus for a year following its completion. However producer Yoji Hashimoto was able to convince them otherwise, and work began on the next instalment as Tsuburaya Productions approached their tenth anniversary. The initial pitch was "Ultra Jack" - a space-based "neo fairy tale" series which would introduce the sixth Ultra Brother and build upon ideas from Ace. While many of the ideas presented would remain in the final version, the trouble was coming up with a name. Jack was a common name in Western fairy tales, but it was also felt to be too similar to "hijacking" - something which was a global issue at the time. So director Kazuho Mitsuda suggested a more Japanese name which conveyed the same idea - and thus Ultraman Taro was born. The series premiered on April 6th 1973, and ran for a total of 53 episodes.
