The 2034 Matsumae Invasion, also known as the Matsumae War was an armed conflict between Neo-Korea and the Republic of Matsumae taking place from the 27th of December, 2033, to the 6th of February, 2034. Following the Sinking of RTS095, Neo-Korea would accuse Matsumae of harboring terrorists who had fired some form of weaponry at the ship, in what is broadly agreed to be an false-flag attack in an attempt to implicate Matsumae. Following the rejection of a series of demands which would have demanded the importation of Neo-Korean troops, the arrest of members of Matsumae's coast guard, and anti-Kāichrén politicians, Neo-Korea would launch an attempted paratrooper assault after a series of cyberattacks on key governmental targets.

This paratrooper attack would fail severely, leading to the death of almost all involved, in one of the greatest aerial military disasters in human history, which was tied to the leadership of the Central Intelligence Services over elite military forces such as the Aerial Assault Grouping, which were then redistributed to the Neo-Korean Ground Forces. Following a period of limited direct conflict primarily carried out via drone strikes on port facilities, elements of Matsumae's Eastern Naval Fleet would be drawn into conflict with the First Reserve Engagement Fleet under Kyo Oki, which they would destroy in its entirety due to outdated missile defense systems, and the outdated nature of the FREF as a whole. The Eastern Naval Fleet would then be destroyed in its own majority, excluding three Taga-class ships, two of which were captured by the Neo-Korean Navy and now serve as the Kogane (formerly Nihomi) and the Hikarikagayaku (formerly Kapiw).

This sacrificing of the FREF would allow for landings to occur on Matsumae, carried out by the First Ground Corps - which would rapidly seize territory through the use of naval support from the Fuzan Central Fleet, alongside an overwhelming air advantage. The FGC would liberate several notable political figures relating to previously existing northern separatism from prisons in the north, with these figures declaring the creation of an independent Republic covering the north of the Matsumae Island, named Fukuyama.

The Kāichrén assault would be stalled on January 29th, with the city of Morioka resisting capture due to both a dedicated defense by local forces and the inability of of the Fuzan Central Fleet to provide assistance during the battle, due to a short exchange of fire between them and the Carrier Battlegroup Prima, which resulted in the sinking of the Kujira-class Destroyer Tatakru-1 and the flight of the FCF as a whole. Following this battle, peace negotiations would rapidly occur due to the fear of future greater intervention, ending in the splitting of the island between Fukuyama and Matsumae, the cessation of relations between Matsumae and Neo-Korea, and the obligation for Neo-Korea to pay reparations to civilians who were harmed in strikes on southern port cities.
