Definitions for "Showa"
The Japanese calendar is tied in with the reign of the Emperor. The term “Showa” denotes the reign of the previous Emperor.

For example, the Godzilla films released in the 1950's, ‘60's, and ‘70's are referred to as the Showa Godzilla series. The Godzilla films released from the 1980's onward are referred to as the Heisei Godzilla series, in reference to the current Emperor's reign.
