Samurai Banners

Fūrin Kazan was the 46th NHK Taiga drama beginning on January 7, 2007. It was aired throughout 2007. The four characters from left to right are wind, woods, fire, and mountain. The title is a reference to the war banner used by Takeda Shingen, which in turn was taken from Sun Tzu's The Art of War. It means "Swift as the Wind, Silent as a Forest, Fierce as Fire and Immovable as a Mountain."
