The Samurai Banner of Furin Kazan

Originally published in Japanese in 1959, this classic novel by Yasushi Inoue takes place during the Japanese Warring Era (1467-1573) - a time when Japan was ruled by three young powerful warlords: Takeda Shingen, Iwagawa Yoshimoto, and Hojo Ujiyasu. The story focuses on Takeda Shingen and his one-eyed, crippled strategist, Yamamoto Kansuke. The brilliant strategies of Kansuke, inspired by his passion for war and his admiration for his enemies' war tactics, are beautifully expressed throughout this book.
