This independent Japanese daikaiju eiga [giant monster film] — which combines WW2 history with giant monster action — seems to be nearer a release in the West, with the appearance of a trailer with English titles (as seen above). For a full report on the film, check out the excellent article on SciFi Japan. Deep Sea Monster Reigo has given rise to a second daikaiju eiga by the same director — Shinkaijû Raiga [aka Deep Sea Monster Raiga] (2009; dir. Shinpei Hayashiya) — but as that was only in production this year, we can’t expect too much international action for a while.
Addendum: As Keith Aiken of SciFi Japan quite rightly points out (see comments attached to this post), it is rather too optimistic to assume that a DVD release in the West is definitely about to happen. I’m sure that it will sooner or later, but there has been no official word as far as I know. My wording above perhaps gives too strong an emphasis to the likelihood and imminence of it.
