Samurai Shodown, known in Japan as Samurai Spirits, is a fighting game series. The stories in the series take place in 18th-century Japan, during the Sakoku or seclusion period of Japan (the first four games run across 1788 and 1789) with great artistic license so that foreign-born characters (including some from places that did not exist as such in 1788) and fictional monsters can also be part of the story. The plot of each game is quite different, but they circle a central group of characters and a region in Japan.
