While to outsiders Japan appears a homogeneous nation (with only 2% of the population being registered foreigners), there are actually key regional differences in the way people behave and the language is spoken. The country's video game developers are no exception.
It's easy to divide the country into East and West Japan — or simply Tokyo and Osaka. For years, it was an easy way to divide the country's video games, too. Sony and companies like Square Enix were viewed as typically Tokyo-style enterprises, while Capcom and SNK were viewed as typically Osaka studios in flavor and style. Then, there's Nintendo, which is an entity in itself.
