Which group ranked just below the tokugawa shoguns in japan's feudal system?

Daimyo

The daimyo were feudal lords which ruled most of Japan after the Meiji period. They were subordinate to the shogun from the 10th to the mid-19th century (the Tokugawa shogunate extends from 1603 to 1868). During the Tokugawa period, there were around 300 daimyo in Japan. It was often from this class that a shogun arose. Daimyo often hired samurai to protect their land. The daimyo era ended with the creation of prefectures in 1871.
