The Snake Head Triad is a crime syndicate based in the city of Neo-Tokyo.
The Snake Head Triad (aka, Sea-Tou) operates in Japan where it directly competes with the Kodachi-gumi Yakuza in the port of Yokohama. They are deeply involved in the smuggling of immigrants and refugees from the impoverished parts of Korea and China, and in the sex trade. Passengers are forced to pay off their debts as indentured labor or via prostitution. The Triad is also a distributor of the Tempo drug.
