I picked up this book after seeing the author's name at the National Arboretum's bonsai exhibit. Yoshimura was the first Japanese bonsai master to welcome international students, and this work is his legacy to the world.
Bonsai are famous for their subtle, simple beauty. Their elegance appears almost effortless, but if you learn anything from this book it will be that training a bonsai is not easy. It takes care and dedication, much like one would give a pet. This discipline is part of the reward in owning and enjoying one.
If you aren't training a bonsai or planning to in the near future, the technical side of the book can get a little tedious. In the end it is a manual designed with the bonsai trainer in mind. There is still value for those wishing to enhance their knowledge and appreciation however, and there are several lovely color plates included. So much goes into not only maintaining a bonsai, but into its aesthetic presentation. How you display one, choose its pot, what you display it with, etc., are all part of the art of bonsai.
When you want to appreciate paintings at a museum better, you read about the art of painting. It is the same with bonsai. Knowing some basics about their styles and forms has deepened my understanding, and thus my enjoyment, of these delightful trees. Everything about them is calming and serene, flowing naturally from the gentle way in which they are raised. You can't help but admire the patient work put into some of them over decades, or even hundreds of years in some cases. Just reading about them brought a sense of peace and harmony, and I hope I get the chance to handle the responsibility of properly training one some day.
