The other reviews are pretty solid on this. It's a beautiful full color book with photos on every page. It does use anglicized Japanese terms for both the tree name and the shapes. I honestly am not mad about that, because I mean...if we're not going to completely culturally appropriate, learning the proper names for things (which honestly may not translate easily) is a part of that.
It has a lot of content about how to care for bonsai but rather than being in one place they're scattered throughout in little 'memo' boxes. I took notes in a separate notebook to have them all in one place. Each tree covered has an 'action calendar' graphic telling you when to do various things like when to prune or fertilize. Each also has a 'management tips' box covering placement, watering, etc. If you can find out which tree you have, this book is invaluable. Even without that, there's plenty of good tips.
Prior to the tree by tree, there's a section on general management, like covering the soil, planting or replanting, wiring, creating jin or shari and types of bonsai shape. I honestly wish this section was a bit longer.
I don't feel like I know enough to start bonsaing a tree but I do know a lot more about the shapes, and the work that goes into it. It appears more 'intermediate' than 'beginner' and I think that's the issue here--it is pitched like a beginner book when it's really not. Still, the pics are gorgeous and you definitely learn how to look at and appreciate this art form as it is intended to be (the connection between pot shape and tree, the various styles of bonsai, etc) in an authentic manner.
