阵营:
中立 (大东亚共荣圈)

日本的国旗 日本 was the leader of the Axis powers in the Pacific Theater. Some consider that World War II actually began with the invasion of 中华民国的国旗 中华民国 by Japan, first by taking Manchuria and installing their puppet the 满洲国的国旗 满洲国 regime. In 1937, after the Marco Polo Bridge Incident, Japan declared war on China, beginning the Second Sino-Japanese War in which Japan invaded and conquered much of eastern China, installing additional puppet regimes along the way, including 蒙古国的国旗 蒙古国 and the "Reorganized National Government of the Republic of China". After invading China, Japan struck southwards, invading and conquering 英属马来亚的国旗 英属马来亚 and the 荷属东印度的国旗 荷属东印度 (Indonesia), in hopes of securing their resources, followed by an invasion of the 英属印度的国旗 英属印度.

On August 6, 1945, the 美利坚合众国的国旗 美利坚合众国 dropped a nuclear bomb on Hiroshima, flattening the center of the city. Late in the evening of August 8, according to the Yalta agreements, the 苏维埃联盟的国旗 苏维埃联盟 declared war on Japan, and shortly after midnight on August 9, attacked Manchukuo and Mengkukuo. Only hours later, the Americans dropped a second nuclear bomb on Nagasaki, destroying a small portion of it. The total shock of these events forced Emperor Hirohito to intervene and compel the big six to agree on the terms of ending the war, taken by the Allies in the Potsdam Conference. After several days of backroom negotiations and failed attempts to destroy the stockpiles of biological and chemical weapons of Unit 731 in Manchuria, which were captured by Soviet paratroopers, and the collapse of the Kwantung Army, in August 15, Hirohito addressed the nation by radio and announced the surrender of Japan. The signing ceremony of the Act of Capitulation took place on September 2 aboard the United States Navy battleship USS Missouri (BB-63).

Geography

Japan is located in the far east of Asia. It is mainly made up of the four major islands: Kyushu, Shikoku, Honshu, and Hokkaido. Japan also owns the Korean peninsular, the city of Quingdao, South Sakhalin and a lot of strategic islands in the pacific including: Taiwan, Okinawa, Saipan, Guam and Iwo Jima. Japan also controls the puppet states of 满洲国的国旗 满洲国 and 蒙古国的国旗 蒙古国.

Mainland Japan is dominated by mountains, which run through almost the entire country. It has a couple of urban areas, namely Tokyo, Hiroshima, and Nagasaki. Flat, arable land can be found around the major cities of Japan.

Japan borders with the 苏维埃联盟的国旗 苏维埃联盟, both directly through the Sakhalin island and the northern Korean border as well as the northern border of their puppet 满洲国的国旗 满洲国. They also border 中华民国的国旗 中华民国 thorugh Quingdao and their puppet 蒙古国的国旗 蒙古国. Mainland Japan is surrounded by sea, with the Sea of Japan to the west, the East China Sea to the south, and the Pacific Ocean to the east.

Historical background

After Japan's unification during the Meiji Restoration of 1868, the Japanese Empire had undergone a period of rapid westernization and industrialization, with the goal of making Japan a power on par with the other western nations. With its newfound power, Japan sought to make up for its lack of resources by securing them overseas, through invading neighboring nations, starting with its invasion of Korea in 1895, the First Sino-Japanese War in 1894-1895, where Japan conquered Taiwan. Succeeding in this, Japan later fought and won the Russo-Japanese War against the Russian Empire in 1904-1905, cementing itself as one of the world's great powers and first non-European nation to achieve this status. Allying itself with the United Kingdom in 1902, Japan joined World War I on the side of the Entente, conquering Germany's possessions in the Pacific and China.

During the Great Depression, the Japanese government had become increasingly militaristic, leading to the conquest of Manchuria in 1931, creating the puppet state of 满洲国的国旗 满洲国. In 1933, further Chinese border territories were also conquered, leading to further puppet states, like 蒙古国的国旗 蒙古国. The Japanese government had begun declaring a campaign of "Asia for the Asians", by which they more or less meant "Asia for the Japanese", claiming a series of wars of "liberation" that were in reality further grabs for land and resources.

The government of Japan is still not satisfied, however, and seeks to further expand Japan's dominion in East Asia, its "Greater East Asian Co-Prosperity Sphere" at the expense of all caught in its way. Japan has countless plans drawn up for its conquest of Asia, some involve an invasion of the Chinese mainland and splitting up 中华民国的国旗 中华民国 into loyal puppets, others calling for an invasion of 英属印度的国旗 英属印度 and others involve invading European possessions in Indonesia and Indochina. Even more tenuous plans call for an invasion of Soviet Siberia, to claim its vast resources and wealth, another plan involves targeting 澳大利亚的国旗 澳大利亚 and 新西兰的国旗 新西兰 with Japan's biggest ambition being the concept of an invasion of the 美利坚合众国的国旗 美利坚合众国 in order to secure the nation's resources and industry and to topple Japan's perhaps biggest rival in the Pacific.

The Japanese Empire stands as the greatest power in East Asia, ready to raze anyone that gets in its way.

Economy

Resource-wise, Japan finds itself in much the same place as Germany. While Japan has access to a satisfactory amount of chromium, tungsten, and steel, it suffers from a shortage of aluminum, and an extreme shortage of oil and rubber. Japan's shortage of oil and rubber at the game's beginning mostly shoehorns the Japanese player into the historical bog of an infantry army. Even a complete annexation of China will not solve Japan's problems, as China has more or less the same resource pool as Japan has. While the Japanese player can trade with the United States in the early game for oil, this ties up civilian factories, and the United States has an early focus to embargo Japan (which they will be likely to pursue with historical focus turned on).

Japan is in luck, however, as all the rubber and oil are a short boat ride and a war with the Allies away. Specifically, the largest supplies of rubber and oil in the game can be found in French Indochina, British Malaysia, and the Dutch East Indies. While Japan won't have complete control of these resources until they reach a peace conference with France, Britain, or the Netherlands, the available resources are more than abundant enough to fuel the construction of planes, ships, tanks, as well as any motorized designs Japan might have for the duration of the war. If the Japanese player does not desire war with the Allies, they will have access to the first technology allowing synthetic oil refineries in 1936, which opens up options for medium-scale production of aforementioned planes, ships, and tanks, without conquest. One thing to keep in mind when taking this route is that synthetic oil refineries are extremely expensive and time-consuming to construct, eating away time that could be used to build up other military and civilian factories with which to build up a force to take all the resources Japan could ever require to fulfill its dreams of Pacific domination.

Military

Here the player can type some informative bits about this nation's armed forces in-game in 1936 and the following years.

Army

In 1936, Japan has mixed seasoned and green troops. Japan starts with 45 infantry divisions, 9 cavalry divisions, 3 light tanks, 2 motorized divisions and a marine division. To reflect historical accuracy, Japan begins the game with a number of divisions that begin with experience 2 and weapons 1. This, combined with the Marco Polo Bridge Incident national focus, allows the Japanese player multiple avenues for warfare with China as early as 1936. Japan also has some troops with basic equipment, good targets for a garrison of Japan's home island and Japan's matrix of pacific islands.

Examples of alternative division template names for Japan include:

  • Mountaineers - Yamahei-dan Shidan
  • Marines - Tokubetsu Rikusentai or just Rikusentai (naval infantry, as opposed to marines)
  • Paratroopers - Teishin Shidan
  • Motorized - Jidousha Shidan
  • Mechanized - Kikaika Shidan
  • Armor - Sensha Shidan

Japan starts with several upgraded tier I ship classes. The Akagi carrier and Nagato battleship in particular have an especially high number of upgrade points. Japan also starts with 3 Kongo-class battleships which are tier II and 2 Mogami-class heavy cruisers that are also tier II. Under construction are 1 Soryu-class carrier, 1 Kongo-class battleship and 1 Mogami-class heavy cruiser along with 3 destroyers and 4 submarines. Japan starts with comparably high naval technology. Japan can also acquire Long Lance torpedoes from a national focus, which gives their torpedoes a longer range than any other nation.

Strategies and Guides

日本的国旗 日本 The Empire of Japan is by far the strongest nation in East Asia when it comes to military strength and has plenty of options for expanding its sphere of influence. That being said, Japan suffers from a chronic lack of resources, given the size of its military and will, as it realized in real life, become very dependent on trade to fuel its war machine unless the problem is properly addressed. Japan is also not a very popular nation globally—the 联合王国的国旗 联合王国, the 美利坚合众国的国旗 美利坚合众国 and the 苏维埃联盟的国旗 苏维埃联盟 all have national focuses that enable them to go to war with Japan and the Together for Victory DLC will also turn 澳大利亚的国旗 澳大利亚 and 新西兰的国旗 新西兰 into possible enemies.

Japan's national focus tree contains many helpful perks and boosts that can greatly assist in early-game endeavors. The National Focus New Naval Estimates gives 4 naval dockyards while "Spiritual Mobilization" and "Warrior Traditions" raise the recruitable population by a noticeable margin.

Japan starts the game with a total of 59 factories (19 military, 25 civilian and 15 naval dockyards) which is comparable to most of the other major nations and this gives Japan the biggest industrial capacity in East Asia.

The Imperial Japanese army consists of a rather colorful mix of units, ranging from Regular to Green in experience and with varying levels of equipment. Many of the division templates are also somewhat questionable when it comes to composition. A lot of rearming and reorganizing will be needed in order to bring up the military to par with the other major powers.

The Imperial Japanese Navy is the third-largest navy in the world and the largest one in East Asia. Because Japan is an island nation and also controls a large matrix of smaller islands throughout the pacific ocean, the navy will be vital to ensure that the Japanese Empire remains properly connected and that supply lines remain open. As such, Japan will need to build up its naval dockyard capacity in order to allow it to expand its naval force and replace lost ships.

Once the initial buildup is completed there are several paths for Japan to take:

Initial conquest options

The Second Sino-Japanese War

Located to Japan's Southwest, 中华民国的国旗 中华民国 presents a relatively early conquest goal for Japan. The Japanese national focus tree contains the necessary focuses to grant a war goal against China very early on in the game and this makes China a perfectly logical conquest option in the early game. When taking on China, the Japanese player must be aware of two crucial facts: first, China has the second highest (highest after unification) starting core population in the game and this grants it a near-bottomless manpower supply. As such, a war of attrition is not an option for Japan as Japan will run out of manpower long before China. Instead, the recommended path is for Japan to strike fast and strike hard, using equipment such as artillery and either heavy fighters or tanks to deal maximum damage to the Chinese forces. Second, it is recommended that the player strike China from multiple directions by opening new fronts through naval invasions. Once the war starts, two possible option for additional strikes would be a naval invasion of the Qingdao peninsula followed by a rush inland to cut off supply line to Beijing or an invasion of Southern China to capture a large portion of China's resources.

Once China falls, the player is left with two options: Annexation or Puppeting. Annexing China will grant Japan a good amount of build slots for construction (which is mostly useless as you have enough construction slots in your capital and way better infrastructure) as well as providing a boost to Japan's resource pool but an immense penalty will be applied to the local recruitable population, greatly reducing available manpower.

If the Japanese player elects to puppet China and has the Together For Victory DLC enabled, then they will be able to fully exploit China's immense manpower pool by recruiting colonial divisions or by requesting forces from China at any point, as China will retain full access to its manpower pool as a Japanese puppet. If the player elects this path, they should only fully annex coastal states, and perhaps even all states except Sichuan (which is the highest population state). China should still be left with enough manpower. Annexing the state of Hainan is highly recommended as this state can serve as a staging area for the Japanese Navy when fighting in Southern Asia.

With 1.9 alongside La Resistance, the Sino-Japanese War can easily turn into a meat grinder for Japan. You want to end the war as quickly as possible as garrison requirement will wear you down by attrition. You can set up collaboration government via espionage beforehand to make things easier and give you an alternative to puppeting China. Be sure to complete Develop Chinese Resources focus first before allowing the collaboration government to form or you will lose out on its bonuses. You can form the Collaboration Government with either Nationalist China or Communist China. Using Communist China as collaboration government might be a preferable option given their better national spirits and conscription laws but you will need more garrison during the time you are completing the focus as the compliance will only form in their starting area. Keep in mind that just like normal puppets, collaboration government will not give you access to their docks and the collaboration puppet will immediately form over all their core territory you possess during their formation which including Dalian, East Hebei, and Taiwan.

Southern Strike

Just south of Japan lies Indonesia and Indochina. These territories are very valuable for Japan as they contain large amounts of rubber as well as a moderate amount of oil, both which Japan sorely needs for tanks, trucks, planes and ships for its military.

Unfortunately for Japan, these territories are controlled by European colonial nations (the 荷属东印度的国旗 荷属东印度 and 英属马来亚的国旗 英属马来亚) and as such Japan will likely not be able to achieve full control of these areas until later in the game unless the player can somehow force through a peace treaty. Still, simply occupying the areas will be enough to extract the resources needed. As far as enemy opposition is concerned, the colonial nations are usually not very well defended so Japan's starting military power alone should be sufficient to capture the colonies if one acts fast enough. Invading the colonies will likely involve a lot of naval invasions or paratrooper drops (depending on personal preference) as well maintaining naval superiority around the islands.

Once the colonies are occupied, a good course of action would be to fortify the coast and station troops in the area to repel enemy attempts at retaking the areas. This is where puppet troops can come in handy, recruiting colonial troops or, if the division templates are good enough, requesting forces from puppets can allow the player to station puppet troops to garrison occupied areas for reducing resistance and repelling or at least delaying enemy incursions.

In La Resistance it is possible to form Collaboration Government on both Malaya and Dutch East Indies using espionage and it might be well worth the effort as your puppets will form immediately once they capitulated without the need of subduing the rest of the Allies. Likewise, be sure to complete Exploit the Southern Resource Area focus first before allowing the collaboration government to form or you will lose its bonuses, though this is only possible in the Fascist path.

Japan's national focus tree also contains focuses to aid in this path, allowing Japan to turn 暹罗的国旗 暹罗 into a puppet as well as pressuring 法国的国旗 法国 to give up Indochina.

Alternatively it's possible to justify on Dutch East Indies or Netherlands in the beginning and temporarily join Axis to take out Netherlands before they can join Allies.

Mid-game conquest options

Indian subjugation

After securing China, one possible alternative is to continue onward to India (the 英属印度的国旗 英属印度) as having both India and China as puppets will more or less make Japan immune to casualties. India, unlike China is a puppet of the 联合王国的国旗 联合王国 so attacking them will likely lead to war with the British. Given that India is very similar to China, possessing near-bottomless manpower but lacking in industry early on, the recommended approach for Japan would be a two-front invasion of India. Specifically, one example would be a land invasion of eastern India through southwestern China (and through Siam if said country has been puppeted) alongside a simultaneous naval invasion of the island of Ceylon and from there to southern India. Another option could be securing 西藏的国旗 西藏, 尼泊尔的国旗 尼泊尔 and 不丹的国旗 不丹 and attacking from that direction as well although this comes with the disadvantage of offering a very chokepoint-heavy attack path due to the Himalayas.

Once again, Japan should preferably strike fast and strike hard in order to not give India any chance to mount an effective defense. This time, however, it is possible that the player may run into British and other Allied troops which presents a challenge in itself as these troops will (typically) be better equipped which can make them harder to fight than the typical Indian division.

Oil Rush

Beyond India (the 英属印度的国旗 英属印度) lies the fifth biggest oil producer in the world - 伊朗的国旗 伊朗. Capturing it will secure twice as much oil as the 荷属东印度的国旗 荷属东印度, providing for Japan's medium-term oil needs as it expands in the Pacific.

Though small and non-aligned, Iran's border with India is very short and very mountainous, making the invasion surprisingly tough (but still a matter of weeks).

Iran also give you access to the 苏维埃联盟的国旗 苏维埃联盟. If the 德意志国的国旗 德意志国 are already close to Stalingrad, an invasion via Armenia could roll up the entire front. If not, you could blitz straight to Stalingrad or even Moscow while the bulk of Soviet forces are tied up in the West (which will collapse when half the front is deployed to deal with your invasion). You can end the war by Christmas.

Continue down under

After securing Indonesia and Indochina, Japan has the option to invade and capture 澳大利亚的国旗 澳大利亚 and 新西兰的国旗 新西兰. Capturing these territories will round out Japan's dominance of Oceania and will also remove the Allies' ability to effectively project power in the south Pacific. Australia and New Zealand are comparable to most European minor nations, possessing good technology but limited manpower. How well defended these nations are if attacked varies greatly; if Australia and/or New Zealand stay loyal to the United Kingdom, it is likely that they will send some of their troops overseas to help their overlord on other fronts. If they choose to sever ties and become independent, however (via Together For Victory), then they will be less inclined to send their troops elsewhere and may therefore be able to mount a more solid defense. In addition to that, going down the national focus trees can lead to Australia and/or New Zealand joining the Axis or Comintern and Australia can even form a faction with the USA, puppet/annex New Zealand and attack Japan.
