Occupied Japan
Occupied Japan is the term used for what used to be Japan prior to the Sino-Korean invasion and occupation. While never properly annexed, most of the Japanese islands are under strict military occupation by now-largely Korean forces, although the majority of the territories are still directly ruled by Reconstruction Committees that are majority Chinese?. Other parts such as Kyushu and Hokkaido are administered by the Joint Committees with a Korean viceroy and a Japanese sub-viceroy.
The political situation on Japan is entirely moot, however, as it is totally subsumed by Korean, Chinese, and Russian corporations. Its precarious position as a long-standing military occupation area has allowed it to become a vast testing ground of the latest surveillance and security technologies on the planet. Despite the prevalence of the corporatist state in countries such as Korea and Finland, Japan is historically the 'first' corporate state, de facto ruled by corporate interests that often ignore the Reconstruction and Joint Committees.
In fact, several Japanese industrial concerns have prospered under this regime and provide a modicum of self-rule for Japanese citizens in the Tokyo Arcology and the Yokohama Industrial Corridor. These corporations, ultimately, have Korean or Chinese creditors, organized in a loose feudal network. Dissent is treated harshly and usually not a problem, but once in a while, the food distribution networks or some part of the security apparatus is prone to accident or sabotage, resulting in bloody clashes between the heavily armed corporate security and various occupying militaries against local dissent.
