Tohl Narita: “This is an attempt to push the limits of having the suit get a man inside.”
While Narita describes as above, integrating the head and body by removing the parts corresponding to the shoulders might have been the same method as the one applied to Alien Zarab.
Nevertheless, I found the shape of Jamyra so impressive when I watched the show as a kid along with how this tragic kaiju who was formerly a human was portrayed in it.
Hiroko Sakurai who played Akiko Fuji writes in one of her books as remarks from Akio Jissoji who directed this episode that Jissoji felt Narita might not have liked Jamyra so much because Narita gave his design of the kaiju immediately without any hesitation to Jissoji when Jissoji asked Narita to let him own the design he found fabulous.
This story could indicate Jamyra was a kaiju that ran counter to Narita’s three principles for kaiju designs as it could be seen as a distorted human form.
It is unknown whether the design of Jamyra included in Narita’s art books (the image on top) was the one that used to be owned by Jissoji.
Tetsuo Yamamura says the costume was seemingly made of a sheet of foam rubber while the method was commonly found among the costumes including those of Bemlar and Pester adding that he dimly remembers the cracked skin was made by spreading latex over the mold and having each piece pasted (onto the body surface) without gaps between each other.
It seems that the upper, the lower part of the body and its arms seem to have been made separately before being put together.
It is known that, although the light of the eyes was accidentally turned off due to an unexpected wire disconnection during the filming, it was allowed to go on without reshooting the scene as Koichi Takano, tokusatsu director, judged that Jamyra’s eyes with the light off could express the kaiju’s agony and grievance more explicitly.
It is explained the switch for the eye lights were set inside the arm to allow the actor, Teruo Aragaki, to operate it.
While I often saw a lad imitate Jamyra by making his face come out of the opening of a round neck shirt so that it ended up getting miserably stretched out, it is hilarious that I have just learnt a figure of a boy with his shirt worn in the funny way was made into a figure set and released from Bandai including Jamyra titled “Mizugiwa-no Jamyra (Jamyra at the Water’s Edge)” in 2015 so they can be placed at the edge of a glass (image at the bottom of this entry)!
