The samurai subgenre, also known as chanbara, features the samurai warrior class and their way of life. These stories explore themes found within bushido, or "the way of the warrior," a moral code that guides samurai attitudes, behavior and lifestyle. Often set in feudal Japan during the Edo period (1603-1868), samurai stories depict the tension between tradition and modernization, the struggle for power and justice, and the decline of a traditional way of life.
