The Afed put out a pamphlet on the state of anarchism in Japan I think - haven't read it but generally they're pretty good so may be worth a read if you're interested in eastern anarchism.
Following Colin Ward's recent death, I picked up a copy of his Very Short Introduction to Anarchism and was impressed - a very concise introduction for absolure beginners.
I know you've read history, but Peter Marshall's Demanding the Impossible: A History of Anarchism is a very broad minded ecumenical work that I recommend.
