Logo: We see a black screen, which then gets engulfed by live-action fire. As the fire covers up the whole screen, a circular logo (like Toho) with Kanji and the Japanese name below rises up to the center.

Variant: There are some black and white and colorized versions.

Technique: Live-action practical effects.

Music/Sounds: A low-pitched, menacing theme that sounds like a dark ambient song (even if dark ambient didn't exist at the time).

Availability:  Seen on their pink film releases such as The Black Snow, Sex Family and Tears of Ecstasy.
