The monster costumes in Japan were known as Kaju. Many of the costumes used were altered into other monsters ( kajus ) in future episodes. Bemlar was altered into the monster Gyango with the revolving antennas. Eli Tsuburaya who created Godzilla was the shows producer who was a master in special effects. Monsters were borrowed from TOHO productions and altered by adding on layers with scales or protrusions. Jirass was basically a Godzilla suit with an added latex collar as seen in the above picture.

Ultraman himself went through three suits:

Type A rough mask with a very small mouth that was able to move but was never able to make it work.

Type B used throughout most of the series with a more angular look to the face and a new latex suit made from an American red wet suit with silver painted on it.

Type C was the last version used in the series and was made with a muscle padded foam body and had less wrinkles in the mid section.
