In a 1992 Famicom Tsuushin interview with the game's producer/designer Hiroyuki Takahashi, he stated that Jogurt/Yogurt was originally just a sketch character made by game's character designer Yoshihiro Tamaki. Tamaki thought the idea would be great to have a completely out-of-place character in the game's battles.

In a 1992 developer team interview featured in the Shining Force Encyclopedia, Tamaki admitted the character was created partially as a joke and before any of the official concept art had been completed. He also stated that Jogurt's face is based on the game's director Kenji Orimo.
