My copy of the Malt Whisky Yearbook 2010 arrived yesterday. The section on Japanese whiskies has been revised slightly but is on pretty much the same basic template as last year's section, which still makes it perhaps the most reliable, succinct source of information about the subject in print.
If you own the 2009 version and are thinking about purchasing purely because of an interest in Japanese whisky, you may find yourself retreading some familiar material, but other sections of the yearbook have been completely rewritten and anybody with a broader interest in whisky will not regret the purchase. I was fascinated by Charles MacLean's article on the early Scottish whisky industry and Gavin D. Smith's contribution about innovations in whisky distilling. Ian Wisniewski's clear but detailed discussion of peating was, for me, worth the price of the book on its own.
