This was re-issued on home video in the United States by SRS, in 2019, under a new title, "Raiga: God of the Monsters". This was to cash in on the (then) current theatrical release, "Godzilla: King of the Monsters" (2019).
The Prime Video version has no English dubbing. Not a problem for viewers fluent in Japanese, nor for anglophones willing to depend on English captions.
