The only conclusion I could come to on this film is that Toho concluded that Frankenstein was the big American monster, so they had to do a movie about him to sell in America. And if that doesn't work, hire Nick Adams.
The plot is that in the closing days of World War II, the Nazis transferred Frankenstein's heart to Japan, where it was brought to Hiroshima and irradiated for good measure. The heart was eaten by a war-orphan who mutated into a Frankenstein who looked slightly imbecilic, but grows to enormous size.
Then there is another subplot with a more conventional Toho Kaiju called Baragon who is tearing up the countryside so the new giant Frankenstein will have something to fight. They then capped it off with a giant Octopus... yes, a giant octopus in the middle of the mountains! I think the director subscribed to the Spielberg theory that if you have the audience for that long, they'll go along with anything.
