 This was the first film that featured Ken Satsuma to wear the Smog  Monster suit. Though small in stature, Satsuma was quite strong for  his size, and was the only one capable of supporting the 300 pound  suit for long periods of time. (Though there were some wire works to  help support.) Satsuma then went on to wear the Gigan costume for  the next two films. After a break of over 10 years, he would be  asked to wear the Godzilla costume for Godzilla 1985, and would  continue to wear it through the Heisei series, and retired after  Godzilla vs. Destroyah in 1995.
