Japan

Japan during the late Warring States period (戦国時代, Sengoku jidai) serves as the main setting of the Samurai Warriors series. Specifically, the particular time zones of interests are the segments which near the unification of the land, the Azuchi-Momoyama period (1568~1603) and the first twelve years of the Edo period (1603~1868). While the first game mainly focuses on Nobunaga's reign of power, the second game expands it and goes in depth with events that happened after his death.

Though the eras share a similar title, it should not be confused with the Chinese Warring States period, which took place in 476 BCE~221 BCE.
