Japan

• Daikyoju Gappa
• Monster from a Prehistoric Planet

From volcanic eruption to monstrous destruction
An expedition to a remote island to gather tropical birds discover the huge egg of a prehistoric animal. The egg is broken when an enormous octopus rised [sic] from the waters of the subterranean lake, and a strange scaly creature emerges, a baby Gappa. The expedition return home with their prize, unaware that two giant monsters are wreaking havoc at the loss of their offspring. Japan is threatened by their fire breathing rage as they turn aircraft and tanks to cinders.
