The original original Godzilla didn’t even have dubbing as I recall. The American version had narration from Raymond Burr as a journalist “translating” what some of the people were saying.
Interesting tidbit: the producer and director of that movie discussed during lunch at a rooftop restaurant of a department store in the famous Ginza distrct how they were going to "destroy" Ginza when the monster rampaged through. Somehow, somebody else at the restaurant overhead them, and when the producer and director tried to leave the store they were detained by the Tokyo Metro police for several hours! (Oops.)
