Nihon (or Yamato, as some call it) is an archipelago and country off the coast of Korea.

After continuous failings from the shogun in power at the time, the country had fractured into multiple states vying for power. During this time most villages and smaller cities would start to support each other in multiple different ways to take the burden off of everyone as the battles went on, these are most commonly cited as some of the first occurrences of communal action and support happening in Nihon.

The clan to eventually reunite Nihon would be met with some internal strife, thus leading to a snap election and a leader with more liberal and democratic views becoming head of the country, a break from the norm of Nihon at this time. Soon after though, this leader would gain the idea to take over Kyoto (the then capital) and the rest of Kansai as a way of gaining control over the rest of the country.

Suffice to say, this worked. By the end of the Sengoku period they would have taken back the entirety of southern Honshu and closed in on Tohoku, leading to the end of the period.

After the civil war Nihon would slowly transition to a constitutional monarchy under the center right 'People for Yamato' faction, these people would keep the already figurehead emperor to gain legitimacy points across the country of Nihon. With the republic being formed, most of the shogun clans were either dissolved or killed off to destroy unnecessary unrest in the nation, leading to the first president being thought of as either a “butcher” or “efficient leader” depending on your political stance.

For awhile though, the nation had slowly become more and more stable and free as the People for Yamato party and many others took it upon themself to help the people in whatever situation they had needed, what marked this period was a slow lowering of poverty rates and a heightening of social services across the nation, this included: welfare services, rehabilitation facilities, and some more.

As colonialism came to a rise, Nihon was met with annexation and take over of the country after Russia had started colonizing the easternmost coast of Asia in an effort to gain power. This resulted in cultural and political shifts towards more leftist attitudes with how Nihon suffered.

Russia had taken upon itself to burn and plunder throughout the country, burning Nihonic cultural artifacts (Shinto Shrines, Castles, etc) which led to extreme contempt towards the Russian government and people. Some people initially did resist in any way they could.

The country had slowly become more and more resistant to occupation though as time went on, mass protests and raids in the capital of the colony (Sapporo) as more and more manpower flooded into the archipelago with people showing extreme resistance.

By the end of the era there had been multiple armed militias associated with the Tohokai Group and Nihonic Socialist Coalition which had started multiple fights with the Russian army. These groups were the first soldiers fighting in the 2nd Sengoku Period

Also known as the Nihonic Civil War. Three main factions had formed during this period: The Sun Restoration (Ni ishin), Nihonic Socialist Coalition (Nihon Akairo Renritsu), and the Tohokai Group.

During the first stage of the civil war, the Russian government had fallen and the Nihon was put into independence after nearly 100 years of colonial rule, leading to a power vacuum first having the Tohokai group take power in Sapporo, then after an assassination and coup d'état from the NSC they were forced into Arakawa with their Authoritarian Democrat counterparts which led to a gang war happening until the end of the war.

Then down in Kyoto a shogun had popped up regarding himself as the “Heavenly shogun to bring Nihon to its golden age”. They were extremely unpopular to say the least, years of democratic rule and colonial rule had bittered Nihon and caused an extreme dislike of any kind of monarchy, despite no successful assassination attempts they were extremely hated and any attempt at furthering public opinion failed horribly.

With the NSC gaining control of Sapporo there was an extreme push out of Hokkaido and into Tohoku and Kanto, the Restorationist force followed suit and the two armies met in Arakawa, leading to a multi-year defense of the city, no other front had moved for the next three decades.

The Tohokai group at this time had suffered even more internal strife as the two NSC and Restorationist armies fought around the city. Though, they soon learnt to adapt and grew roots down into the city, farming in closed off and hidden settlements so they could feed anyone in their faction. These roots are the main cause of the NSC having so much trouble securing the city in the post-war years

During these years many charity services had popped up on both sides, the biggest of these is the Kurimoto Support Group (KSG). Ran mainly by Yukino Kurimoto and her daughter Yumiko Kurimoto, the KSG had widened its suppport across the entirety of Nihon as the war neared its end. They are the reason most civilians lived during the war and why Fuyutsuki is now considered a famous location in terms of history for Nihon.

Nearing the end of the war, Zhongguo had started giving support and supplies to the NSC in an effort to combat Rigasian influence in Asia, this led to the Arakawa stalemate breaking and the NSC steamrolling through the Restorationists territory. The Restorationists did receive support from Rigasia after Zhongguoan volunteers and arms flooded into Nihon but, the supplies and volunteers hadn't made it there in time and sooner or later the NSC had taken Kyoto and won the civil war.

As the civil war came to a close, the country had suffered extreme drops in stability to the likes of the early first republic. One example of this is Arakawa: the Tohokai Group still had control over the city and werent giving it up, this lead to a multi-year long siege of the city that soon led to the Tohokai group falling back all the way to Edo Castle, which was eventually raided by the NSC Army.

After a few years though, most of the country had started to calm down and grow more. Yukino Kurimoto and Yumiko's sister Hana took it upon themself to help out with supporting the people as the country transitioned back to a democracy and stable economy under the NSC. For the most part the country in the modern era is stable and economically well off with support coming in from Zhongguo.

On the international stage however, Nihon was cut off from most powers associated with Rigasia as it became a socialist state associated with Zhongguo, most people in Nihon have qualms with Rigasia and any outsiders supportive of them after documents and information regarding them supporting the Restorationists came out.

The government had undergone a multitude of changes as well after the war and Russian colonial era, first of all instead of the presidential democracy seen in the first republic, the country had become a direct democracy with more radical left leaning views. UBI had been enacted in the later years, in a shock to the rest of the international community, same sex marriage + inter-racial marriage had been legalized in Nihon under the new constitution, leading to multiple civil rights activists pledging support to the nation.

One of the other things that had been done under the NSC was a kind of split up of the nation in a way similar to the United States of America in our timeline. Each local government of their respective region has control over legislation not mentioned by the federal government.
