During the Ashikaga period, Japan witnessed significant cultural growth, mainly influenced by Zen Buddhism. The period saw unique Japanese arts such as tea ceremonies and flower arranging attain new heights. Odi Nobunaga unified Japan by defeating the large forces of Imagawa Yoshimoto, thus, bringing peace to the region. In the ear of the Tokugawa, the role of the Samurai changed because they became increasingly courtiers, bureaucrats, and administrators instead of being warriors. During this period, many people gave up fighting and became traders leading to the development of vibrant urban culture.
