Genocide

All the insects on Earth become wild and attack humans, causing Armageddon.

The film's staff includes Shizuo Hirase as the cinematographer, who also worked on the Shochiku films "The X from Outer Space" and "Goke, Body Snatcher from Hell". Composer Shunsuke Kikuchi, who also worked on "Goke", does the music here; he may be best known today for "Female Convict Scorpion" or perhaps "Dragon Ball Z".

Because this was the last horror film Shochiku would produce, it is suitably ambitious and apocalyptic. This is dark, bleak, and edgy beyond what we typically see from horror of the era, especially in Japan. We (at least Americans) expect men in rubber suits to beat on each other, but this is a far worse menace!
