Well the book as a whole for knifemaking I think is great, but there's a lot of misinformation in the Japanese-style section. I won't try to correct everything, but here's a few examples:
The diagrams for lamination techniques (pages 156-159) aren't very accurate.
Mentioned many times is the term "yakiba" as the temper line. This is not the correct terminology. Yakiba is actually the hardened area from the edge to the hamon.
None of the "more common shapes and cross sections" in the diagram on page 162 are accurate at all.
The 2 mounted Engnath knives on page 166 and 167 are not mounted as tanto properly. Also notice how all the hamon in those pieces are really dark? That's from over-etching, you don't want the hamon to be really dark.
On page 166, it may have just been a simple slip in interpretation, but pure clove oil is not desirable for traditional pieces.
That's just skimming stuff off the top of my head (and finding the pages in the book that apply). I don't think it's intentionally misleading, but it's not what I would consider a very good source of information for that stuff. I rather enjoy the book overall, but the Japanese section isn't very good.
So mind you I'm not trashing the book, but it's not a very good source of information that the thread originator was looking for in my opinion.
Addendum: I also want to clarify that not all the information in the section is bad...but the bad information--especially the shapes and cross sections--tends to offset the good. It doesn't give a very good example of a finished piece, and it can give beginners a false sense of what is "correct." That's why I don't suggest it, when there are much better references available.
