In Way of the Samurai 4, you must take on the role of a master-less samurai looking to establish yourself in this conflicted land of opportunity and uncertainty. Set in he humble port town of Amihama during the mid 19th Century, several years after the arrival of the "black ships" from the West ended Japan's long history of cultural isolation. It is up to you to decide which faction to support in an almighty conflict amongst the region's three powers, and so direct the course of Japan's history.

Set in the port town of Amihama in 1855 a ronin interacts with, fights against, and aids a variety of people while aligned with either the pro-government forces, the anti-government rebels, or the British Navy stationed at the port town attempting to negotiate a peace treaty.
