Old Jack City
The oldest of the megas, Shiawase was the first corp to claim extraterritorial status. A classic Japanese zaibatsu, Shiawase is run in a traditional “family” style, with most employees signing lifetime contracts and even marrying within the corp. Families, however, tend to squabble, and plenty of runners have made good cash in the course of these quarrels. As for what they do, what don’t they do?
Either directly or through subsidaries, Shiawase has its hands in nuclear power, environmental engineering, biotech, heavy industry, technical service, minerals, military goods, and a whole lot more.
