Bushido, the Soul of Japan

Bushido: The Soul of Japan written by Inazo Nitobe
is, along with the classic text Hagakure by Tsunetomo Yamamoto, a study
of the way of the samurai. A best-seller in its day, it was read by many
influential foreigners, among them President Theodore Roosevelt, President John
F. Kennedy and Robert Baden-Powell. It may well have shaped Baden-Powell's ideas
on the Boy Scout movement he founded.
