The name Suikoden is a Japanese pronunciation of the Chinese word Sui Hou Chuan (literally means Water Margin). "Water Margin" is one of the four great Chinese historical novels, the others three are "Dreams of the Red Chamber", "Romance of the Three Kingdoms", and "Journey to The West". The 108 stars concept is originally in the "Water Margin". The story is about 108 people who were forced by the Song dynasty government to become bandits. They joined up in the Liang Mountain and opposes the government. Their leader is Song Jiang.
Konami took the concept of the 108 stars and replaced the orginal characters with their own. The name of the stars remain the same, except with Japanese pronunciation.
Suikoden's name and the 108-star concept is taken from the Chinese novel Sui Hou Chuan (Water Margin).
