Showa

Showa era and Showa period, is a term used to identify the years between 1926 and 1989 under the reign of Japanese Emperor Hirohito.

The first Godzilla film was to begin the Showa era of the kaiju industry, and is the usual kaiju to be affiliated with this era. During the beginning of this era, Godzilla was mainly antagonistic in nature, taking on the likes of Anguirus and Mothra.

By the time of Ghidorah, the Three-Headed Monster's release, Godzilla adopted what would soon become his most famous image: a heroic monster, battling terrible villains with other monsters by his side.
