The sculptor of Ultraman was Toru Narita, who was originally asked to create and design an alien monster, for Ultra Q. In the final stages of production, it was canceled. However, under the direction of Narita himself, staff art Kymio Sasaki was told to repeat the work by molding clay, and the mask and body were created. The suit was created based on the model of Bin "Satoshi" Furuya, who was Ultraman's suit actor. Some model changes were made due to damage. Three types of suit exist: Type A (from Episode 1 to Episode 13), Type B (from Episode 14 to Episode 29) and Type C (Episode 30 until the end of the series). In every mask of Ultraman, each of the two eye-holes has a small dot at the bottom that resembles a pupil. These dots are not pupils; they are actually small holes through which the suit actor can see outside of the suit. In some newer suits, the dots are less visible to others. In the film Ultraman Mebius & The Ultra Brothers, the suit made was based on the classical Type A suit.

The skin type of the material is latex. Movement for the mouth was considered by the development team, but it felt too unnatural, and was canceled. The Ultraman suit is very intense, and is not very damaged by aging; therefore, it is a very durable suit. The suit has been manufactured to fit the body and shape of the person inside. Different suits have been made as time passes, for different uses such as new Ultraman series, films and even live shows. The quality of suits from The Return of Ultraman to Ultraman Leo (series) are not as good as the one from the original Ultraman series. The latest suits show a more modern-looking Ultraman, as technology develops, more detailed suits are made for the films.
