Based on a suggestion
from Phillip Jones, inspired by novels by Robert Conroy and
Paul
Hynes.
Following the declaration of war by the Soviet Union and two
uses of the new atomic bomb superweapon by the United States, the government of
Japan felt no other option than to agree to the sweeping demands of the Potsdam
Declaration made July 26. The points from Potsdam were extensive, including
occupation, reduced Japanese territory, a disarmed military, an economy under
reparations, and unconditional surrender with “stern justice… meted out to all war
criminals” and “those who have deceived and misled the people of Japan into
embarking on world conquest.” Yet when Minister of Foreign Affairs Shigenori
Togo showed the declaration to Emperor Hirohito, they both agreed it was the
best they could expect, especially with its promises to defend Japanese nationality
and personal freedom.
As word spread through the Japanese military of the plan to
surrender, officers became fearful. Although the declaration promised no
enslavement of the Japanese, many of the points could be taken to extremes for
an effective foreign control of Japan in every aspect of the nation’s politics,
culture, and even raw materials. While the upper echelon of Japanese government
conferred with the emperor in a bomb shelter, Major Kenji Hatanaka sought out
those who balked at the idea of such surrender. Although the general consensus
was that the emperor’s word would be the final decision on the matter, War
Minister General Korechika Anami was at last convinced that the fate of Japan
was being sealed by despondent whispers in the emperor’s ear while he and other
senior officers were kept away in a room nearby.
Late on August 14, the Second Regiment of the First Imperial
Guards arrived to join the first at the palace. This was interpreted as
reinforcements against a coup, but Hatanaka had already convinced the guard
officers of his plan. Hatanaka approached General Shizuichi Tanaka, commander
of the Eastern District Army, with orders from Anami to stand down any defense
in face of the coup. The palace was sealed, and all of those who did not wish
to go forward with the coup were ordered home. Hirohito was kept within the bomb
shelter while all non-military ministers were taken to rooms that would become
their prisons. The emperor’s recorded announcement of surrender was destroyed
and replaced with Hatanaka’s announcement of a new government that would fight
invaders to the very end.
News of the coup in Tokyo rocked the Allied world along with
the remnants of the Empire of Japan. The United States dropped “Third Shot,”
another “Fat Man”-type atomic bomb, on Tokyo on August 21, where it devastated
the city even though most of the officials had moved to bunkers and the
populace had largely already been bombed out. More A-bombs fell that autumn on Yokohama,
Kokura, and Sapporo. Violence broke out in several places on the Home Islands
with those who defied the coup, including a march on Tokyo to liberate the
emperor. Meanwhile, several commanders abroad refused to acknowledge the coup
also, either surrendering to Allies themselves or declaring a sort of
neutrality with promised ceasefires against Allied troops until clearer orders
came from Tokyo.
Soviet forces moved immediately that August into Manchuria
and stormed Korea as quickly as possible before winter slowed them. The raw numbers
of soldiers were fairly matched between the Japanese and Soviet armies, but the
Japanese aircraft were outnumbered by more than 3 to 1 and tanks outnumbered
nearly 20 to 1. The Japanese military fought a rolling retreat, many returning
from the Korean peninsula with only a few heavily fortified ports left behind.
After the loss of Manchuria, the Japanese continued southward through China
while fighting Chinese freedom fighters (both nationalist and PRC) at the same
time. All through the retreat, Japanese troops used scorched earth tactics with
destroyed infrastructure as well as improvised booby-traps, echoing the Soviets’
own defense against the advancing Germans just a few years before on the other
side of Russia. The Soviet invasion of Sakhalin, the Kuril Islands, and northern Hokkaido
went much the same with strategic objectives met at great tactical cost.
The American and British Commonwealth Allies rolled out
Operation Downfall’s first act, Operation Olympic, with a landing on the
southern end of Kyoshu Island on X-Day, November 1, 1945. The coup government
had affirmed its control of Honshu through the fall, but Kyoshu was still
greatly divided. The Allies’ plan was to secure airbases for the next stage of
invasion northward. As the coup’s control weakened and locals lost faith in the
government’s “Glorious Death of One Hundred Million” under Operation Ketsugo,
numerous Japanese officers and cities offered to surrender and even join the
fight to defeat illegal captors of the emperor. Kyushu became the battleground
of civil war.
Following the island-hopping strategy from earlier in the
war to take key strategic points for forward moments while leaving others alone,
extensive Japanese holdings in Southeast Asia and Indonesia remained untouched.
Communications became increasingly disrupted, however, prompting regional
Japanese commanders to establish themselves as local warlords. Several launched
raids to strike at bases in Australia, the Philippines, and even India in hopes
of distracting the British and Americans from their advancement northward.
Regardless, in March 1946, Y-Day began the Allied invasion
of Honshu with landings at the Kanto Plain south of Tokyo. It was double the size
of landings at Normandy with more than 25 divisions in the first round coming
ashore. Allies’ fear of repeating the Battle of Okinawa across the whole of the
island were met. The coup government concentrated its forces against the
invasion, which fought a grueling battle for every inch of the war-devastated
land. Veterans from the First World War compared it to No Man’s Land. Tokyo
fell, and the coup government fled toward the Hida Mountains still holding the
emperor.
Through months of battle, many Japanese soldiers held out in
hopes of a devastating typhoon that would cut of Allied supply lines and drown
the troops much as had been seen with Mongol invasions centuries before.
Instead, that July and August typhoons Janie and Lilly went on a more southerly
route and did little to impact the middle-island fight. By fall, when the
emperor was freed by a Japanese anti-coup covert mission, there were only a few
holdouts in strongholds scattered across the western Pacific. The emperor declared
the war over, although it had long ended in many areas scarred by explosives,
radiation, and crop-killing chemicals.
The rebuilding of Japan continued over long decades. Many
Japanese emigrated from the most war-torn areas, shifting the population map
away from what had once been the most densely urbanized. Millions left the
islands completely, either accepting offers from Allied countries for resettlement
or to neutral nations like Brazil, where some fifteen million people of
Japanese background live today. Cold War fears prompted American investment in Honshu
and Kyushu, hoping to stem the spread of communism from China, Korea, and North
Japan, which had become “the East Germany of Asia.” Escape by boat from
communist countries to Japan and the Philippines became notorious between the
two sides of the Cold War, prompting an “Iron Sea” of intensive communist patrols
to mirror the Iron Curtain across Europe. Oppressive Soviet rule would continue
until Moscow’s collapse in the late 1970s after cultural turmoil across Central
Asia and dragged-out quasi-wars in Southeast Asia.

In reality, the coup known as the Kyujo Incident failed. Anami
was said to have asked others about the possibility of a coup’s success, but
everyone agreed to abide whatever order the emperor gave. The officers even
signed an agreement as proposed by General Torashiro Kawabe while they waited
for the announcement in the bomb shelter. Anami, Hatanaka, and others committed
suicide within hours of the attempt. The surrender notice went out as planned
on August 15, and Japan surrendered formally aboard the USS Missouri on September 2.
