There is strong implication that the 1954 Godzilla was the only survivor of his habitat because of the artwork and what Yamane says. He says that Godzilla's habitat was totally destroyed, and the artwork shows all of the other Godzillas being blown away by the blast, while one single Godzilla stands still and absorbs the blast. Yamane's implication at the end of the film is that there are still other Godzillas out there, and that one will appear if nuclear tests continue. The second Showa Godzilla likely lived in a different underground pocket, and like the previous Godzilla was awakened and irradiated by a nuclear test.
