Shogi Books in English
Unfortunately, there are only a few Shogi books available in English. Check amazon.com with keyword "Shogi" If you know of other English books, please let me know.
I have not read the first two books. But from the look of table of contents, these books appears to explain Shogi plays from very basics to some gaming strategies and problems.

This is a new book published in 2009. However, it does appear this is a reprint of "Shogi Japan's Game of Strategy" by the same author published in 1993.
