Fūrinkazan
Fūrinkazan (Japanese: 風林火山; "Wind, Forest, Fire, Mountain") is a popularized version of the battle standard used by the Sengoku period daimyō Takeda Shingen. The banner quoted four phrases from Sun Tzu's The Art of War: "be like a wind in a rapid march, a woods in a steady march, a fire in a raid, a mountain in a standoff."
