ultra-useful information on tiny print space

I bought this book when I was first in Japan and could not stop reading it. When I travelled in Nepal, I took it with me, and all those of my Nepalese friends who were into learning Japanese (quite a few) were equally fascinated with it as I was, so I left it there. When I got back I immediately bought it again -- so much info on so little space! The images also helped me remember. Buy it!
