I have to admit, this was enjoyable to write. Available from Kindle (and if you don't have a Kindle, the app for iPad, iPhone or Android is free to download) "But Why? - The Essential Beginner's Guide to Japan" covers hundreds of subjects about life and living in Japan. Written to help newcomers make sense of the world they've landed in, old hands will recognise the things that make Japan such a fascinating and sometimes confusing country.
The book covers subjects as diverse as a quick history of the last four hundred years in under one page to asking whether Tokyo is Japanese. I hope you enjoy and if there are any questions please leave them in the comments below.
