The Coup d'état of the Japanese Shogunate, also known as the 12/5 Incident, was a civil war event in the Empire of Japan that took place on the 5th of December, 2001, as a result of several actions taken by the civilian government over the years that cast them in an increasingly negative light in the eyes of the populace. One such example was the evacuation of the villages around Mount Tengen when the volcano threatened to erupt, with the government going as far as to use force to remove unwilling civilians, and the poor conditions of refugee camps used to hold such civilians evacuated from other dangerous areas or awaiting resettlement.
Another example, more deep-rooted than the first, was the increase in foreign power in Japan; US forces were once again allowed into the nation as garrison forces despite them quickly pulling out of the country during the 1998 BETA invasion of Japan and the establishment of the UN-controlled Yokohama Base, as well as the use of two G-Bombs on Japanese soil during Operation Lucifer in 1999 despite strong objections. These are just a handful of examples of the "increases in foreign power" viewpoint held by many of the coup forces.
The coup was instigated by Captain Sagiri Naoya of the Imperial Mainland Defense Force's 1st Tactical Armor Regiment, of the 1st Capital Defence Division, with the purpose of securing the Shogun as their new leader and the routing and retreat of any force against his ideals. His fiery speeches against the current government also inflamed the hearts of many Imperial Japanese personnel to join his cause, giving him command over several squadrons of TSFs, veterans from the Fuji Tactical Fighter Training Group, and even assets in the Imperial Japanese Aerospace Force.
History[]
Lightning Strike[]
Some time before the coup, Sagiri and several members of the IJA/MDF banded together into a research group aimed at improving battle tactics. It is suspected that this was used as a front for gathering his forces in preparation for a swift first strike.
The coup began when Sagiri's forces attacked Tokyo, killing numerous members of the Imperial Diet, including Prime Minister, and besieged the Imperial Palace with the intention to capture the Shogun; Sagiri's position as commander of the IJMDF's garrison in Kyoto allowed the coup forces to move quickly without much resistance. Sagiri himself personally executed the Prime Minister of Japan and other high-ranking parliament members, accusing them of treason towards the Empire of Japan and its people. Imperial Royal Guard units quickly assembled for a first-strike against the coup forces, but with little result.
Around Japan, other IJA/MDF units, some loyal to Sagiri's cause, others against his actions, moved into position as well. Some of the IJA/MDF forces against Captain Sagiri were stationed outside Yokohama Base, to prevent the United Nations from intervening immediately, as they did not wish for the matter to escalate into one requiring foreign aid.
Escalation[]
The conflict would start in earnest after nightfall, when a soldier in Kyoto began firing towards the direction of Royal Guard forces, and did not stop until he was executed by his commander. Taking it to mean a total breakdown in negotiations, the Royal Guard forces backed by American reinforcements and Sagiri's troops engaged each other in earnest, the same act repeating itself across Japan as coup forces engaged garrisoned American troops.
Soon, the provisional government at Sendai authorized UN and US forces to intervene in the situation; Yokohama Base would deploy the 207th Training Unit as the 207th Tactical Armored Platoon to assist in the situation, backed by US troops in the vicinity and joined by Tsukuyomi Mana, Kamiyo Tatsumi, Ebisu Minagi, and Tomoe Yukino of the Royal Guard's 19th Independent Guard Flight. The US 7th Fleet, at that time moored offshore Sagami Bay, would also be incorporated into UN command as part of the intervention operation plan.
Unknown to all but a select few, the Shogun, Koubuin Yuuhi, had been escorted out of the Imperial Palace some time ago; the 207th TAP later encountered her, her retainer, and Ministry of Intelligence operative Yoroi Sakon when they were stationed at their positions. Taking the Shogun into their custody, they originally planned to evacuate the Shogun to a safer area, but were pursued by enemy forces.
Special Task Force A-01 and the XM3[]
The Special Task Force A-01 was deployed in secret to the region and managed to hold back the area, to the shock of the advancing rebels.The Rebels, expecting conventional TSF combat, sent Flights in waves to clear the area, but were caught completely off guard by the agility and crazy maneuvers allowed by the XM3 OS installed in Special Task Force A-01's TSFs and were killed or defeated before having a chance to react or adapt to the combat situation.
The XM3 offered such an overwhelming advantage that the rebels couldn't kill or damage a single Valkyrie throughout the entire engagement, 2nd Lt. Takahara even exclaimed in disbelief that with the new OS they were capable of fighting against the "Elites of the Imperial Army", but ironically this was seconds before her TSF was cut in half by Lt. Komaki Sayoko, leaving only an arm of hers remaining. This sent the rest of the Valkyries into a state of anger or shock and caused some to break down or lose concentration (2nd Lt. Akane was almost killed because of her friends death but she was saved at the last second by Captain Isumi who was fighting off Lt. Komaki at the same time).
After the death of Takahara, both leaders snapped their respective troops out of their daze and after the two sides continued to engage, 1st Lt. Hayase is shocked by the rebel's sudden rapid change in movement, allowing 1st Lt. Komaki to break through and clash with Isumi, she is then berated by her Captain for looking away and not pressuring the enemy at all times. Other Valkyries had a similar shock when the rebels began predicting her attacks and avoided incoming sniper fire.
Meanwhile Komaki clashes against Isumi and accuses her of being a traitor, but Isumi retorts she's a member of the UN and demands her surrender. The rebels continue to fight and suffer casualties, despite Isumi's continued orders of surrender, until Sagiri managed to sneak behind the defense line to reach the Shogun, during which Komaki was defeated, but spared from death, by Captain Isumi. Afterwards Sagiri surrounds the forces transporting the Shogun and announces a ceasefire.
Cease Fire, Negotiation and Betrayal[]
With other coup forces catching up, the UN/US troops were forced to engaged Sagiri's forces, and were in danger of being surrounded when the US Army's 66th Tactical Armor Group Hunter, led by Major Alfred Walken, arrived to assist them while the STF A-01 continued to hold off other enemy reinforcements.
As their escape neared, the combined group was cut off when Sagiri led his forces in a pre-emptive strike, using transport aircraft of the 671st Airlift Group to drop his troops into position, despite the risks of being shot down by Laser-class BETA from the Sadogashima Hive, surrounding the Shogun. He then announced a ceasefire and gave one hour for the Shogun, who had collapsed at the time, to be handed over.
After the Shogun recovered, she thanked the people who fought for her sake and, to the shock of everyone, bowed in respect to the foreign soldiers who risked their lives for her sake. She then announced her intention to duel with Sagiri and giving him the noble suicide he seeked, but was stopped by her body double, and twin sister, who proposed a different plan. Unknown to Sagiri, the real plan entailed switching Yuuhi with her twin sister, pilot cadet Mitsurugi Meiya of the 207th TAP and have her, as the impostor, meet with the rebel leader and talk him out of the coup while the real Shogun watched from a safe distance.
The negotiations went well, with Meiya managing to connect with Sagiri on an emotional level, feeling and understanding his pain and the reasons for the coup. With tearful eyes she showed him the hypocrisy of his cause and pleaded with him to stop to the coup, to which Sagiri agreed after some hesitation.
As the non-rebels began to rejoice at the end of the civil war, 2nd Lieutenant Irma Thesleff fired without warning and killed the wing-men that escorted Sagiri to the Shogun, causing all plans to collapse. After a brief period of shock, Sagiri rationalized that he was just back-stabbed by the Shogun. He then ignored all further cries from the Shogun and ordered his forces to engage the enemy. Still believing that the Shogun was with the UN TSF that carried Meiya to the negotiations, many coup pilots went after Takeru and his Fubuki, and were only stopped by Major Walken. However, Sagiri successfully engaged and destroyed Walken's sabotaged Raptor, and then targeted the 2nd Lt. Shirogane's TSF, fully intent on destroying it and the Shogun with it, but Lt. Tsukuyomi Mana stepped in and engaged Sagiri, saving the two.
The battle did not end until Sagiri was defeated by Tsukuyomi. After Sagiri's death, the rebels gave up on their coup and allowed the 'Shogun' to continue undisturbed, forming two long files for her and her escorts to fly through. It is not mentioned what happens to the more stubborn coup forces who refused to surrender after hearing of Sagiri's death (or if any indeed refused to do so), but it is likely they were defeated by the UN/US/Royal Guard troops.
Aftermath[]
Any coup-aligned IJA/MDF forces that were still alive surrendered, including the remaining members of the Fuji Tactical Fighter Training Group. A temporary cabinet led by the Shogun was brought in to keep to keep the citizens calm and the country functioning.
Investigations into the cause of the coup also revealed that the events of the entire battle might have been orchestrated by other elements not allied to Sagiri; 2nd Lieutenant Thesleff's sudden disregard of the ceasefire order was attributed to pre-mission application of battlefield hypnosis, which was triggered at that exact moment to cause a breakdown in communications. Major Walken's F-22A also showed signs of software sabotage, as his weapons were locked at a crucial moment where he had no reason to do so, and by his own wingmate, which was confirmed to be a likely CIA agent.
The CIA in general were suspected of having an involvement in the whole coup, as the base that the Hunters received their F-22As, Langley Army Base, was known to have hosted CIA operations before. They might also have forced the coup (as evidenced when Sagiri began gathering those of like mind), since the death of the Shogun and the coup leaders would have allowed a greater presence of foreign power in Japan in the name of "keeping the peace".
An alternative suggestion is increasing support for Alternative V by showcasing the world the fragility of the current stalemate, humanity's inability to keep together, and the superiority of Alternative V's G-bomb-optimized strategy as opposed to the yet-uncompleted Alternative IV. Yet a different suggestion has the blame on members of the Imperial household as power-hungry villains who want the Shogun out of the way.
In other aspects, the F-22As of the 66th Tactical Armored Battalion Hunter performed admirably during this battle, showcasing the world the true extent of the United States' military might, as well as their intentions and technological prowess. The Japanese fared poorer in that extent, wasting many lives and equipment to bring this coup to its bloody conclusion.
The superiority of the XM3 is proven during the coup, however many within the forces, Eishi and non-Eishi alike, still doubted its reliability, leading to the XM3 trials and the following incident afterwards. When Shirogane pilots a Shiranui after the XM3 trials incident, he is shaken by it's power compared to the Fubuki he was piloting. He mentions that if they weren't equipped with the XM3 they would not have survived against the rebels during the incident.
Trivia[]
- During his last moments in the MLA manga, Sagiri Naoya was seen closing his eyes as his TSF approached Tsukuyomi Mana's. This heavily implies that Sagiri allowed himself to be killed. This might be because Sagiri thought he was back-stabbed by the Shogun, the raison d'etre of his coup, and no long had any will to continue to fight.
- Though it was never explicitly said so, the wing-man that accompanied Sagiri to the Shogun must have been someone Sagiri greatly trusted, otherwise he never would have brought him to meet the Shogun.
- As a testament to their opponent's skill, whenever a Valkyrie put their guard down for a second, they were killed, almost killed or endangered another member.
- There is a translation error in the fan translated English Alternative manga on page 13 of chapter 28. The phrase "They're pushing back 2 other platoons" should instead read "They're pushing back the 2nd platoon".
- Although this arc is meant to be serious, English speaking fans often find it hilarious due to certain scenes that break all the built up tension. This includes the "English can eat shit" scene and many scenes with badly pronounced English sentences such as "Rushan Karazu?" and many others.
