'The Art and Architecture of Japan' is an interesting overview of the three main artistic fields: sculpture, painting and architecture. It is divided into two parts, the first one touching the first two, the second totally devoted to buildings. They have been written by different historians.
For a general and synthetic view, it is a very good book. It's main problem is the fact that all its pictures are in black and white. The original text is also a bit old, but it has been tweaked and revised, and put up-to-date with notes (specially the second part). I give it 4 and not 5 stars because of the pictures, which in an art book (and more so with Japanese art, extremely colourful), you miss a lot from the use of B & W. If you can get it cheap, it is still a great general guide.
