Gamera Wiki

The Heisei era (平成,   Heisei?), or Heisei period (平成時代,   Heisei jidai?), was a political period of Japan which started in 1989 with the ascension of Emperor Akihito to the throne, and ended with his abdication in 2019. Films produced during this era, such as those of the Godzilla or Gamera series, may be identified as the Heisei series (平成シリーズ,   Heisei shirīzu?) of their respective franchises. While the Godzilla films of the Millennium series and beginning of the Reiwa series were released during the Heisei era, they are not counted in the same series due to coming after hiatuses in the franchise and not following the same continuity.

Other major kaiju franchises have not followed this convention despite having similar hiatuses; for example, Gamera the Brave is considered to be a part of the Heisei series, despite being released seven years after the previous film, Gamera 3: Revenge of Iris. It is important to note that Gamera the Brave is not part of the same continuity as the Heisei Gamera trilogy, and its events are completely unrelated to the events of the previous three films.


Gamera series[]

The Gamera Heisei series began in 1995 with the release of Gamera: Guardian of the Universe and ended in 2006 with Gamera the Brave. The first three Heisei Gamera films were directed by Shusuke Kaneko and all share continuity, while Gamera the Brave was released much later by Kadokawa and is a standalone film unconnected to the continuity of the trilogy.

Gamera series[]


  • It is a common misconception that Gamera the Brave is counted as part of the Millennium series. The Millennium Series only applies to the Godzilla series, as Japan was still in the political Heisei era when it was made. In Japan, Gamera the Brave is sometimes referred to as the "Shinsei version" (新生版,   Shinsei-ban?) to distinguish it from the trilogy.
  • In the Heisei Gamera trilogy, all of Gamera's opponents can fly. The only monster in the entire Gamera Heisei series thus far that is unable to fly is Zedus.
