Plot
The story takes place in Japan in the 1860s, a time of cultural assimilation. Two samurai, Munezo Katagiri (Masatoshi Nagase) and Samon Shimada (Hidetaka Yoshioka), bid farewell to their friend Yaichiro Hazama (Yukiyoshi Ozawa), who is to serve in Edo (present-day Tokyo) under the shogunate of that region. Though the position is desirable, Katagiri voices his concern that a man of Yaichiro’s character is likely to get into trouble. His doubts are confirmed when the married Yaichiro expresses an intention to indulge in Edo’s sensual pleasures while stationed there.
