It is explained online that it was Shōji Ōtomo who introduced Maurits Escher and René Magritte to Japanese people for the first time along with the “Star Trek” TV series.
It seems that he started being involved with Tsuburaya Productions around the time when the TV show “UNBALANCE” that was to turn “Ultra Q” in a while was being planned. As the show was planned to be produced with the cooperation from a group of Japanese sci-fi novel writers to work out the plots in the first place, Ōtomo might have got involved in the show through that channel.
It was him who devised each precise setting for the hero and kaiju characters and the equipment used by the defense teams with the anatomy illustrations and cross section illustrations based on his ideas even apart from the depictions or descriptions found in the shows.
The settings he specified such as Ultraman’s energy limit putting it as three minutes and Zetton’s light ball allegedly given out of its mouth as one trillion degrees Celsius were incorporated into the official settings by Tsuburaya Productions (I hadn’t known he set the energy limit as three minutes until recently).
On the other hand, it also seems to have been Ōtomo who caused dispute afterwards by adding the subtitle that could be seen as offensive to atomic bomb victims to Alien Spell so that Ultraseven Episode 12 featuring the alien has been banned since then in Japan.
It is said that he was so meticulous about his work and such a demanding boss that three editors who had worked under him resigned when the publishing company Kodansha regularly had his articles appear in their magazines.
Chances are that Ōtomo was finally banned from Tsuburaya Productions because Hajime Tsuburaya, Eiji’s first son, took a dim view of the way Ōtomo had dealt with their kaiju characters perhaps by taking the liberty of stretching the stories and settings at his discretion.
