Sun in the Last Days of the Shogunate (1957)

Set in the last few years of the shogun's rule, this period/ensemble movie depicts the lives of the young and the restless at a whorehouse. The protagonist is Saheiji, a resourceful, witty free spirit. It's 1862, 6 years before the Shogun turned his political power over to the Emperor.

Saheiji soon endears himself to them all and solves many whorehouse disputes with his wit. But it is slowly revealed that the seemingly perfect Saheiji is suffering from tuberculosis and his future is uncertain...
