Quite a title, eh? I have tried translating it but it is seems to be a making of book for at least the original Gojira. The only thing at this time which I can comfirm is that it is comming out on the 26th. More information to come... hopefully.
UPDATE: Thanks to KG member G-MATT, the title has been translated to read: "Godzilla, Unpublished Toho SFX Archives Material: Producer Tomoyuki Tanaka and His Era".
