Toho is changing the titles to allow them to register the films under these new titles, which were not previously released in the US under (with the slight exception of INVASION OF THE ASTRO MONSTER), and working around the old titles they were released under by AIP, Continental, UPA, etc. Retitling GHIDRAH as GHIDORAH, Toho "fixes" the title to conform to the name the character's copyright is registered under, "King Ghidorah."
