Managed to track down a sealed copy.
It looks like an LP reissue, but it isn't!
It even smells like an LP, minus the actual vinyl and paper sleeve smell.
The Japanese sticker reads "Deka-Jake" or Big Jacket. I guess there are many more of these reissues that have LP-sized packaging.
Japanese reissue from mid-2000s(?) with an extra track.
It even has Japanese liner notes.
Pretty cool.
