World at large

Canada:As world war 3 raged around them canada held their own strengethening their army and securing their borders the canadian having decvided as the war began to not participate as they had nothing to gain even as american fell the canadian army held their borders against their enemies and in the ending days of the war made an uneasy peace treaty with japan the japanese would cease assault of the canadian borders if the canadian goverment agreed that they would ally themselves with the japanese in any future wars and would allow for free trade between their countries. In the long years after the war as the world was recovering canada prospered from its untouched land and open trading with the now half global empire of japan.

The Republic New Mexico: During the height of the war new mexico seceded from the united states and formed its own goverment using the confusion and the fact that america was focusing its war efforts on keeping china from entering its borders the now republic of new mexico quickly attacked mexico crushing its goverment and army in one fell swoop as theirs soldiers marched on the unsuspecting mexican governement. Quickly emulating mexicos remaining troops into their own fighting force the republic of new mexico secured its newly obtained borders and weathered through the rest of the war even reppeling multiple attempted assaults by the japanese. After the war the republic of new mexico became a militaristic state stockpiling arms and munitions and scavenging what experimental technology they could in order to replicate it and create weapons from it eventually becoming a major world power in the world at large in the current day.

New United states:After the war and japans conquering of over half of the world those living under japanese rule in the central and eastern united states became restless after years of waiting and planning they rebelled driving the unsuspecting japanese back to their main foot hold KasaiHana city after driving the japanese back the people of the New United States created walled citys interconnected by long walled roads the areas outside of these citys and roads becoming wild untamed places as time went on (think the old west but with better wapons and more rape and cannabalism)

United kingdoms: In the early days of the war the UK was conquered by china and stripped of what little resources it had eventually being abandoned as a useless husk with a large population and little to food remaining towards the end of the war. After the war a cult arose known as the cult of the true god using the countrys withered and broken state to their advantage the priests of this new religion set themselves as men of power ruling over the british people claiming to be those who are "truly beloved by god" whom god sent a message to saying that they were to inherit the earth and all its riches. making the men who helped them to rise to power known as "truly beloved by god" they set a new social order with those who were truly beloved by god ruiling over those who were not thus the united kingdoms enterd a dark time a time where rape and murder and slavery by those who ruled the land ran rampant so it remains till this day silently building an army in order to one day spread their religion across the world

ukiyo:This utopian floating city measuring three times the size of hawaii with the ability to house tens of thousands was built by a conglomerate of the rich and famous in the early days of the war in order for them to escape the main brunt of the fighting. after being built   it was quickly commendeered by the american military which used it to house the worlds greatest scientists of the time and their families leaving them with a small but well trained number of troops they set the island afloat in the south pacific ocean where it remains floating till this day as time went on the population of the floating city flourished the people there focusing on advancing science as their main task. being left relatively unharmed by the worlds goverments it remains floating still housing the greatest scientists of the new era developing experimental technology for the world in order to better human life regardless of nationality.

South America: Not much is known about south america in the current age all that is known is that all communications from the country ceased shortly after massive fire bombing raids were performd on the continents major citys towards the end of the war. Known now as a deadzone of the world it has yet to be explored atleast not succesfully with exploration teams sent to the continent have all dissapeared   in some cases along with the military escort that was sent in to protect them. storys circulate about it being an unholy place now where wild tribesmen and unknown beasts roam. The exploration attempts ceasing in the year 2100 after severe loss of personell from the attempted exploration of the continent.

Japan: The spark of world war three was lit by japan though those outside of its goverment at the time would know nothing of it. seeding doubts between china and america in the days before the war they slwly created a rift before feeding false evidence of attack plans to both countrys and igniting the fires of war. through careful speech japan was able to convince both sides that it was working under them by gaining information on the other essentailly pretending to act as a double agent for both sides in this way they were able to stay largely unaffected by the war and receive military assets from both sides for the means of "defending themselves" staying quiet the japanese waited for the right moment. With america, china, and most of the world in dissaray from the war the japanese struck their troops quickly conquering the eastern hemisphere and most of the western hemisphere in an unbelievably short amount of time.

Russia:Though officially under japanese sovereignity Russia was never truly conquered even after the breaking of its central goverment the destruction of the majority of its military power the russian people and what remained of the military moved into the deep wildernesses of russia building small homesteads and continuing to harass the japanese colonies within russia to this day.
