Not sure if it will help with your quest, but the story of how I came across my copy might be of use. There was a seller from Japan on E-Bay who I had dealt with on a couple of occasions. I asked him if he would be interested in helping me locate a few items, one of which was this book (another was a Marui Mothra larva). Apparently the book was readily available in Japan and he located me a copy (in excellent shape) in less than 2 days, for a measly $100. The Mothra took a little longer, and cost $250 more, but I digress...the point is, if you have (or ever plan to) deal with a Japanese seller, just ask if they can help, it's always worked for me!
