After a treacherous expedition to retrieve a giant valuable opal, disaster strikes as the opal reveals itself to be an egg which spawns Barugon, a dog-like demon from Hell. Armed with a deadly tongue that can freeze anything in its path and an explosive rainbow beam, Barugon wreaks havoc on Japan. Gamera (Teruo Aragaki), who in this film turns good, arrives just in time to save Earth. Stars Kojiro Hongo and Kyôko Enami. This is the Japanese language version of War Of The Monsters (also available here at Rare Movie Collector). (In Japanese language, with English subtitles).

This film comes from a rare widescreen import print, which has far superior picture quality than the U.S. version.
