A History of Japan by R.H.P. Mason and J.G. Caiger
I read A History of Japan in January 2016
A History of Japan tries to tell the whole history of Japan within 400 pages, quite a formidable job, and actually does a very good job.
The book covers Japanese history from the time of legend, up until World War Two, the occupation and the economic miracle in the second half of the 20th century.
