Japanese State Army
— General Yoshihide Yoshida, Address to the Nation, June 2025
The Japanese State Army (JSA) is the primary successor state to the government of Japan following the Necronyl Collapse of 2025. Formed through the invocation of the National Emergency and State Defense Act, the JSA represents the consolidation of the former Japan Self-Defense Forces (JSDF) into a unified, authoritarian military apparatus.
Operating out of the fortified Ichigaya Citadel, the JSA is currently engaged in a multi-front war against the "Necrosis" hordes, anarchist insurgencies in Osaka, and the collapse of global civilization. While nominally defending the Japanese people, the JSA is characterized by its draconian Sakura Protocol, which authorizes the summary execution of infected citizens and the suspension of all human rights within the Quarantine Zones.
Background: The Collapse
The distribution of the Russian pharmaceutical Necronyl in early 2025 was heralded as a medical miracle. By May, the miracle had rotted. The resulting pandemic did not just kill; it reanimated. As the "Necrosis" spread through bites and fluid contact, the Japanese civilian government found itself paralyzed by bureaucracy and Article 9 of the Constitution.
With the police overwhelmed and the healthcare system shattered, the National Diet held its final emergency session. Under pressure from the military brass, they passed the National Emergency Act, effectively dissolving the civilian cabinet's power and transferring supreme authority to the General Staff. The JSDF was formally disbanded and immediately reconstituted as the Japanese State Army, freed from the legal shackles of "Self-Defense."
The Sakura Protocol
The defining doctrine of the JSA is the Sakura Protocol (桜の議定書), a set of engagement rules that redefines the legal status of Japanese citizens. In the eyes of the JSA, the conflict is not a police action, but a biological war of annihilation.
- Total Containment: Quarantine Zones are absolute. Any unauthorized movement in or out is met with lethal force.
- Class-7 Designation: Infected individuals are stripped of personhood and classified as "Class-7 Biological Threats." Neutralization is mandatory.
- Asset Denial: Areas deemed unrecoverable are to be firebombed to prevent the infected biomass from spreading to the Safe Havens.
Military Organization
The JSA has abandoned the branch rivalry of the former JSDF, streamlining into functional commands tailored for the apocalypse:
- Ground Command (Rikugun): The bulk of the forces. They man the walls of the Safe Havens and conduct "Purge Raids" into infected territory.
- Naval Command (Kaigun): Responsible for the "Steel Wall," a blockade ensuring no infected vessels reach the remaining safe ports.
- Scientific & Medical Corps (The SMC): A controversial branch led by former civilian virologists. Rumors persist that the SMC uses captured infected—and political dissidents—for live experimentation to find a cure.
- Hunter-Killer Regiments: The elite of the JSA. Highly mobile units equipped with experimental anti-bio weaponry, tasked with hunting "Alpha" variants of the undead.
Relations
- United States Remnant (Yokosuka): Strained. The USFJ remnants hold their bases but refuse to submit to JSA command.
- Osaka Free Zone: Hostile. A coalition of anarchists and surviving yakuza who reject JSA martial law.
- The Infected: Total War.
