Good Book, not Parshall though
Format: Kindle
The author uses more Japanese terms than any similar book that I've read but uses western naming conventions for Japanese people. I don't quite know what to think. Good diagrams.

Interesting front to back
Format: Hardcover
Really good book. A lot from the Japanese perspective. Plenty of facts but not so much as to be boring. Amazing how much was hit or miss back then. Or just plain luck.

An important book
Format: Kindle
A very good treatment of the subject matter, especially valuable as it mines the Japanese sources, which have largely been ignored by the Western historians. The narrative is clear and easy to follow & background detail gives important context into the psychological aspects of the events. Definitely recommended!
