Also, for those of you who DO have the book, there is presently a translation being done to order. Contact Uwe (member on the forum) if you'd like to be included. The more people we have, the cheaper the translation will be for each subscriber.
I have two of these books, got them off Amazon.jp. However, I'd sell my wife to a biker gang for a copy of the Big Book of Dr. Sasama. I think Dave has a copy of this book. Hint, hint.... She'd fit in your luggage on the way back!
