How did a feudal society develop in japan?

The Kamakura shogunate managed to repel Mongol invasions in 1274 and 1281, aided by a storm that the Japanese interpreted as a kamikaze, or Divine Wind. The Kamakura shogunate was eventually overthrown by Emperor Go-Daigo, who was soon himself defeated by Ashikaga Takauji in 1336. The succeeding Ashikaga shogunate failed to control the feudal warlords (daimyo), and a civil war erupted (the Ōnin War) in 1467 which opened a century-long Sengoku period.
