> [Zen at War] meticulously documents Zen Buddhism's support of Japanese militarism from the time of the Meiji Restoration through the World War II and the post-War period. It describes the influence of state policy on Buddhism in Japan, and particularly the influence of Zen on the military of the Empire of Japan. A famous quote is from Harada Daiun Sogaku: "[If ordered to] march: tramp, tramp, or shoot: bang, bang. This is the manifestation of the highest Wisdom [of Enlightenment]. The unity of Zen and war of which I speak extends to the farthest reaches of the holy war [now under way]."

> The book also explores the actions of Japanese Buddhists who opposed the growth of militarism.
