I don't know squat about the Japanese language, but the titles are different?
Armin, can you interpret?
The first release was called KAIJU SOSHINGEKI (怪獣総進撃), which translates roughly as All Monsters Attack.
The rerelease was titled GOJIRA DENGEKI DAISAKUSEN (ゴジラ電撃大作戦) which means Godzilla Lightning Attack Strategy.
The
Lightning Attack Strategy is a military term and it probably refers to the German "Blitzkrieg" strategy from WW2, so maybe Godzilla Blitzkrieg Attack would be a better translatation.
