It's a bit of a frustrating read, to be honest. Reading through it seems like someone tried to put the whole of Japan into one book. And while I get why you would want to do that, it shouldn't be the purpose of a travel guide.
Here's what i mean. When talking about architecture, especially the modern and contemporary one, you get references to about 20 buildings, maybe a sentence for each and 3 images for 3 of them. While that may be ok for other people, it just frustrated me to no end because I had to google for the rest of the 17 to get an understanding of why these buildings were mentioned in the first place and what they looked like. And that's essential when planning a visit to a foreign country. You need to know some essential pieces of info to be able to prioritize.
The same goes for the other topics listed in this book, like arts for instance. References to numerous painters and painting and no images to help you visualize the actual work and how the craft might have evolved through time. Again, lots of google-ing to be done. Same criticism goes for museums and other places etc. It would have been a lot better to have a top 10 interesting buildings spread across 5 pages with details on why the building is important, why you should go see it etc. And for some of the other place, there's instances where there are pictures that take up almost the whole page with "busy street" or "bridge on the way to X place" and not of the place itself or what it looks like on the inside.
Other annoying details just keep piling up (like referencing Japan's historical periods like this: "during the Heian period (see pp. 30-31)", instead of just mentioning the years for that time period) to make this a disappointing read. And I am very sorry, because I was definitely looking forward to learning about this beautiful country. I guess, this wasn't the guide for me.
