Something I've always wondered. In general, the rights to one of Toho's Godzilla films seems to include both the original Japanese version, as well as any US cuts, provided that materials exist. But I do believe there are exceptions to this rule.
Godzilla, King of the Monsters seems to be considered a separate film. It was given a theatrical and home video release in Japan, and I believe Toho licenses this out as an entirely separate film than Godzilla. Is that correct? If so, what is the rationale for it? Does it have to do with the amount of footage cut or added, or does it go back to something specific to the original agreement established with US movie makers?
Godzilla 1985 was released to home video in Japan. The parallel here is obvious, since it continues the story line from King of the Monsters, although the edits are much less extensive. Is this considered a separate film by Toho? Do they license it separately?
Do any other films in the series follow this pattern?
