Fūrinkazan (風林火山), literally "Wind, Forest, Fire and Mountain", was the battle standard used by the Sengoku period daimyo Takeda Shingen, quoting chapter 7 of Sun Tzu's The Art of War: "Move as swift as a wind, stay as silent as forest, attack as fierce as fire, undefeatable defense like a mountain."
The original Chinese appears separated in two consecutive passages:
Chapter 7, passage 13: “故其疾如風，其徐如林“ Let your rapidity be that of the wind, your compactness that of the forest.
Chapter 7, passage 14: “侵掠如火，不動如山“ In raiding and plundering be like fire, be immovable like a mountain.
