Ohashi also seems to have been involved in the production of the kaiju TV series “Agon” aired in 1968 (4 episodes).
It is explained online, although it was produced in 1964, the broadcast was delayed as they couldn’t get any sponsorship.
According to the information on the Net, the Toho people protested that Agon’s design was a rip off from Godzilla, but the dispute came to an end as it was figured out that Ohashi was also involved in sculpting the first suit of Godzilla.
Nevertheless, as there seem to be the crew members involved in the production of the movie who maintain they had never seen Ohashi on the set, the truth remains unknown.
While Agon and Magma Taishi’s Aron certainly look alike, it seems that the costume of Agon also had a balloon in the neck to be blown up to show the inflation and deflation of the throat just like Aron.
Ohashi seems to have claimed that it was him who taught Ryosaku Takayama how to deal with latex to model monster costumes.
Besides all these, Ohashi is alleged to have been involved in making many of the ape masks and hands for the 1968 US movie “Planet of the Apes” after participating in the production of the 1967 UK 007 film “You Only Live Twice” as an art member.
