When Tan Renhao accepted a new mission and began to prepare for the war between the Empire and the United States, the focus on the battlefield was still on Japan's side. According to the tradition of the empire, as long as Japan is not finished, the empire will never easily shift its focus, and after defeating Japan, the empire will be free to clean up other enemies.

There were three theaters of operations against Japan, two of which were under the responsibility of the army and one by the navy.

The Army is responsible for the Korean Peninsula and the South Seas, both of which are supported by the Navy. Of course, this is not the main battlefield, it is only to ensure the interests of the empire, as well as to lay the groundwork for future wars.

The fighting on the Korean Peninsula ended at the end of August. The Imperial Army deployed forty-five divisions here (most of which were actually reserves), and with the assistance of hundreds of naval bombers and a large fleet, the last Japanese troops besieged in Pusan surrendered on August 25. It was two years and ten days after the outbreak of the war, and Japan's dream of landing on the Korean Peninsula was completely shattered.

Fighting in the South Seas continued until early December. In mid-October, two Marine Divisions and three Army divisions landed on Timor Island with the support of Task Force 1 and thousands of Army and Navy aircraft. The fighting on the island continued until early December, when the last Japanese forces were annihilated in Dili and the Japanese presence in the South Seas was completely wiped out.

The focus of the war against Japan remained in the direction of the Japanese mainland, and strategic bombing became the main force for the destruction of Japan, and. This was also the main force that sent Japan to hell completely.

After the Japanese emperor was defeated at the end of May, the empire conveyed a request for surrender to Japan through the Brazilian government, saying that as long as Japan was willing to surrender, the empire would guarantee the integrity of Japan and provide some help to Japan to restore its livelihood after the end of the war. This was Japan's last chance to avoid disaster, and as a result, the Japanese misunderstood the meaning of the empire. It is believed that the Empire's demand for a unilateral "truce" at this time was actually the reason why the Empire was unable to fight any longer. In addition, judging by the information collected after the war. At that time, Japan firmly believed that as long as it held out for another six months, at most a year, the United States would enter the war, and then the Tang Empire would be defeated. If Japan surrenders before the end of the war, as it did in the last World War, it will be humiliated again. And after the war, it was abandoned again and again trampled under the feet of the Tang Empire. Therefore, the Japanese military government immediately rejected the "demand" for surrender. Perhaps, the Japanese did not know that this was not a "request" of the Tang Empire, or an implicit expression such as "demand", but an ultimatum to Japan and a notice of death in Japan. And the Japanese themselves signed this notice.

On the 4th of June, after the deadline had passed, the Acting Prime Minister of the Imperial Cabinet personally issued an order to bomb Japan indiscriminately, that is, all visible man-made structures were within the scope of the bombing, without exception. There is no longer a distinction between military and civilian targets, no longer between political and military targets, everything that can be blown up is on the list of bombings.

On 5 July, more than 1,100 bombers from seven bomber regiments bombed Tokyo intensively, dropping more than 3,000 tons of bombs and almost completely destroying the city. In this bombing, only sixteen bombers were shot down (forty-five returned with wounded), and the fighters escorting the bombers lost eight. And in the fierce bombing, at least a hundred Japanese fighters were shot down.

On the 8th, the bomber group again made a collective sortie. Concentrated bombing of Osaka, Japan's second largest city. Nearly 3,000 tons of bombs were dropped, burning the unblemished urban areas of Osaka to the ground. And in this bombing. Only a dozen bombers did not return, and dozens of Japanese fighters that took off to intercept were shot down.

On the 11th they bombed Nagoya, on the 14th they bombed Nara, on the 18th they bombed Kobe, on the 21st they bombed Okayama, and on the 25th they bombed Kochi. On the 30th, the bombers of the seven regiments were dispatched separately to bomb more than 10 small and medium-sized cities on the Japanese island of Honshu. At this time, the incendiary bombs stored on Iwo Jima and Ogasawara Islands were once again used up.

On the 31st, more than 30 bombers shouldered a special mission. None of the bombers carried incendiary bombs or bombs, but instead filled their bomb bays with leaflets. More than 30 bombers flew over more than 30 cities in Japan and dropped tens of millions of leaflets. In addition to slogans urging Japan to surrender and demoralizing the Japanese military and civilians, the leaflets included a long list of cities that were within bombardment. This was not to warn the Japanese to leave the cities as soon as possible, but to paralyze the Japanese war machine, and when the workers went to the countryside to escape the bombing, the Japanese factories could not function.

At the beginning of July, the Marines had already laid siege to Mt. Hachijo, and the thousands of Japanese troops trapped in the mountain were making their last stands. On 3 July, the second front-line airfield on Hachijo Island was built, and the second batch of three squadrons of "Hayabusa" fighters were stationed. In addition, a batch of improved fuel tanks that can hold 500 liters of aviation gasoline was delivered to Hachijojima. The "Hayabusa" fighter can carry out a two-and-a-half-hour combat patrol mission over Tokyo after carrying such a secondary fuel tank, which greatly improves the performance of the fighter. Beginning on the 4th, two squadrons of fighters will go to the skies over the Japanese mainland every day to carry out free hunting missions.

These fighters on free hunting missions generally work in groups of two (later gradually increased to four, or even eight), specifically looking for lone Japanese fighters, or transport planes carrying out transport missions and reconnaissance missions over the Japanese mainland. In addition, the "Falcon" fighter can also carry eight rockets, or two 50-kilogram bomblets, and has a certain ability to strike on the ground. Its main bombing targets were automobiles, trains, and river vessels.

The fact that fighter jets began to carry out free hunt missions actually marked the loss of air supremacy on Japan's homeland. As early as the end of May, the Imperial Navy fighter jets deployed on Jeju Island were already carrying out free hunting missions in the western part of the Japanese mainland, but the scale was not large. So the received ground effect is not very good (the endurance of the "Vulture" is not enough). By August, there were already four fighter squadrons ready for free hunt missions, and by the end of the year, the bomber unit no longer needed escort fighters, and all ten fighter squadrons deployed to Hachijo Island (and later after the construction of the third front-line airfield, ten fighter squadrons were deployed on Hachijo Island) could be used for free hunt missions.

Strategic bombing against Japan resumed on 5 July. Four fighter squadrons covered eight bomber regiments (the latest one was transferred at the end of June, and the airfield on Chichijima was already available to the Strategic Strike Force) to bomb the Japanese city on the island of Honshu again. More than 3,500 tons of bombs were dropped. By mid-July, the number of bomber regiments deployed on Iwo Jima and Ogasawara Islands had reached 12 (the on-shore airfield on Brother Island was transferred to the Strategic Strike Force on the 12th). This is the full strength of the 1st Army of Strategic Strike. Jiang Shikuan, Mao Tingdun, and Liu Xiangzhi were promoted to brigadier general division commanders and continued to lead the bomber unit to carry out bombing missions. Luo Yunchong was also officially promoted to the rank of Major General of the First Strategic Strike Army (previously only acting commander).

At the end of July, six bomber regiments on Jeju Island formed a strategic strike second army, and Liao Hanxiang originally wanted to send Hao Dongjue over and serve as the acting commander of the second army. Hao Dongjue refused. At the end of July, he returned to Zhoushan and remained within the scope of the naval aviation.

By the end of July, the Tang Empire's strategic bomber forces had dropped a total of 180,000 tons of bombs and incendiary bombs (including about 150,000 tons of incendiary bombs) on the Japanese mainland, and all the major cities on the Japanese mainland had been bombed, and eighty percent of the medium-sized cities with a population of more than 200,000 had been bombed. The bomber units of the Don Empire had already begun to drop bombs on small cities, towns and villages, and even villages.

Beginning in August, the intensity of the bombardment continued to increase. In addition to continuing to fight those there are also industrial targets. In addition to bombing large cities, more than 2,000 bombers of the two strategic strike forces began to bomb some tactical targets, including railways, roads, bridges, and so on. When bombing these targets, most of them are high-explosive bombs. Instead of incendiary bombs, this also actually solves the problem of the lack of incendiary bombs.

In the same month, some strategic bombers also undertook a new mission, that is, to go to Japan's inland seas, lay mines in ports, and block Japan's inland sea communication lines. Part of the bombers (fighters) even began to bomb ships operating in the inland seas of Japan. At the same time, the Empire's submarine forces began to operate in the coastal waters of Japan, attacking merchant ships sailing close to the Japanese mainland. Some submarines don't even let go of a windsurfing board!

The Second Army was also expanded with three additional regiments of bombers, in addition to continuing to support the Army's all-out offensive. The focus has shifted to bombing Japan.

The month of August. The bombers of the two armies dropped 230,000 tons of bombs (mines) on Japan alone, and almost every bomber had a mission every day. At least one mission every two days. Among them, more than 15,000 mines have been launched. Judging from the post-war data, within a month, 250,000 tons of merchant ships sailing in Japan's inland and coastal waters were sunk by mines, and this month, only 180,000 tons of merchant ships were sunk by the Imperial Submarine Force.

The bombing of Japan in September became even more onerous as the end of the year approached and the Japanese ground air defense fighter unit collapsed almost entirely. At that time, each bomber had two crews (including aviation crews). This ensures that the bomber is in top condition and that the pilots and crew are well rested. Almost every bomber flew two bombing missions a day, one to bomb a ground target, and the other to lay mines.

Within a month, more than 3,000 bombers dropped 250,000 tons of bombs (incendiary bombs) and 25,000 mines on the Japanese mainland, bombing more than 60 Japanese cities, destroying more than 10 important bridges, destroying more than 100 locomotives (mainly the results of the "Hayabusa"), damaging more than 1,000 vehicles, and sinking more than 30 large ships in Japan's inland and coastal waters. In addition, escort fighters and fighters on free hunt missions shot down hundreds of Japanese aircraft, including more than 100 fighters.

Over the next three months, the bomber group set new bomb (mine) records in a row. By the end of the year, the two armies (the Second Army had expanded to 12 regiments) had dropped a total of 1.5 million tons of bombs (incendiary bombs), 120,000 mines, and tens of millions of leaflets (which were often more powerful than bombs). According to information obtained after the war, by the end of '23, Japan's industrial productivity had fallen to about 20% of its pre-war level, at least 25 million urban dwellers had fled to the countryside, and more than 70% of Japan's factories had been bombed into ruins. More importantly, with the beginning of a large number of mines, Japan's inland sea and coastal routes have been completely blocked, and Japanese ships and warships are afraid to leave the port. Japan's sea communication with the United States has also been largely cut off (this is the credit of the Imperial submarine forces), the famine has broken out, and there is not even enough to eat on the belly, how can the Japanese still fight?

It can be said unceremoniously that the strategic bombing of Japan was a complete success. From the beginning of '23 to the end of '23, in just a few months, the Imperial bomber forces destroyed Japan's national foundations and disintegrated Japan's combat effectiveness. Although the strategic bombing of Japan was not directly related to the Korean Peninsula and the Nanyang battlefield, it was precisely such a fierce bombing that left the Japanese army without ammunition to fight and the soldiers without food to fill their stomachs, and the Japanese invading forces were quickly defeated.

The strategic bombing of Japan also proved that bombers could write a new history. Since Du Hei put forward the theory of "air supremacy", this is the first time in human history that strategic strike force has been used on a large scale in war. Relatively speaking, the bombardment between Germany and Britain, France, and Russia on the European battlefield was nothing. It was precisely because of this that Germany later bought strategic bombers in large quantities from the Tang Empire (and later established its own strategic bomber production plant), and most of the "wolf doves" were later sold to Germany at a low price (because the Tang Empire had better bombers), which also fundamentally changed the situation on the European battlefield.

The war against Japan was not over, and as long as the Japanese militaristic government did not announce its surrender, the bombing would continue. In the words of Zong Hanqin, the acting prime minister of the empire, it is better for Japan to have no grass than for the Japanese militarists to survive. Only when Japan announced its surrender would the Reich's bombers stop dropping bombs on the Japanese mainland!
