Which Asian country was controlled shoguns and samurai from the twelfth century to mid nineteenth century?

Japan was the Asian country controlled by shoguns and samurai from the twelfth century until the mid-nineteenth century. The shogunate system established a military government where shoguns held actual power, while the emperor remained a symbolic figure. This period, known as the feudal era, was marked by a strict social hierarchy and a strong warrior culture dominated by the samurai class. The era ended with the Meiji Restoration in 1868, which led to significant modernization and the establishment of a centralized government.
