中立 (大东亚共荣圈)

日本（Japan）是轴心国在东亚与太平洋新秩序与战场的领导国。第二次世界大战最早发端是1931年日本入侵中华民国开始的，并成立了满洲国傀儡政权。在1937年的卢沟桥事变后，日本正式向中国宣战，第二次中日战争进入全面抗战阶段，期间日本入侵并征服了华东大部分地区，并在此过程中建立了其他伪政权，包括蒙古国以及汪精卫国民政府。在入侵中国后，日本也开始向东南亚进攻，入侵并征服了英属马来亚和荷属东印度（即现在的印度尼西亚），获得了其丰富的资源，然后准备入侵英属印度。

1945年8月6日，美利坚合众国在广岛投下了一枚原子弹，夷平了整座城市。根据雅尔塔协议，8月8日傍晚，苏维埃联盟对日本宣战，并于8月9日午夜过后不久突进了满洲国和蒙古国。仅仅几个小时后，美国人在长崎投下了第二枚原子弹。这些事件彻底震撼和迫使裕仁天皇介入并迫使六大巨头商定结束战争的条件，这是盟军在波茨坦会议上决定的。幕后谈判持续了数天，同时在战场上也没能在苏联伞兵突袭之前及时销毁满洲731部队生化武器库存，以及关东军的崩溃后，8月15日，裕仁天皇通过广播向全国发表讲话，宣布日本无条件投降。投降书的签字仪式于9月2日在美国海军战舰密苏里号上举行。

地理

日本位于亚洲的远东地区，它主要由四个主要岛屿组成：九州，四国，本州和北海道。日本还拥有朝鲜半岛，天津、南桦太以及太平洋中的许多战略性岛屿，包括：台湾，冲绳，塞班岛，关岛和硫磺岛。日本还控制了满洲国和蒙古国的地区。

日本本土以山脉为主，几乎遍布全国。它有几个主要城市，分别是东京，广岛和长崎。日本主要城市周围都有平原。日本直接通过萨哈林岛和朝鲜北部边境以及满洲国的北部边境与苏维埃联盟接壤。他们还通过天津及其傀儡国蒙古国与中华民国接壤。日本本土四面环海，西面是日本海，南面是东海，东面则是太平洋。

历史背景

在1868年明治维新期间日本统一之后，大日本帝国经历了一个快速的西化和工业化时期，其目标是使日本成为与其他西方国家同等的强国。日本以其工业力量，通过侵略邻国来弥补本土资源的匮乏，例如始于1895年对朝鲜的入侵，1894-1895年的甲午战争，日本占领了台湾。继此之后，日本又在1904-1905年抗日战争中赢得了日俄战争，巩固了自己作为世界大国之一和第一个获得这一地位的非欧洲国家的地位。1902年，日本与英国结盟，在第一次世界大战中加入了协约国，征服了德国在太平洋和中国的殖民地。

在大萧条期间，日本政府变得越来越军国主义，并于1931年征服了中国东北，从而造就了满洲国傀儡国的成立。1933年，日本进一步占领中国领土，导致了更多的傀儡国，例如蒙古国。日本政府已经开始宣布一场“亚洲是亚洲人的亚洲”的运动，在这场运动中，他们或多或少的意思是“亚洲是日本人的亚洲”，并发生了一系列的“解放”战争，实际上这是对土地和资源的进一步争夺。

但是，日本政府仍然不满意，并以牺牲一切为代价的方式，寻求进一步扩大日本在东亚及其“大东亚共荣圈”的统治。日本为征服亚洲制定了无数计划，其中一些计划是入侵东亚大陆，并将中华民国分裂为一些忠诚的傀儡国，另一些计划则是入侵英属印度，其他则涉及入侵印度尼西亚和印度支那的欧洲国家殖民地。甚至更甚的计划要求入侵苏联，以夺取其西伯利亚的丰富资源，财富和广大领土，另一项计划涉及对准了澳大利亚和新西兰，而日本最大的野心便是入侵美利坚合众国，以确保日本的资源和工业控制权，并推翻美国政府，以便日本称霸太平洋地区，从而成为一个洲际大国。

日本帝国是东亚最强大的力量，随时准备摧毁任何阻碍其前进的国家。

在资源方面，日本发现自己与德国处于大致相同的位置.虽然日本可以获得令人满意的铬、钨和钢铁，但它却遭受了铝短缺以及石油和橡胶极度短缺的困扰。游戏开始时日本的石油和橡胶短缺主要将日本玩家硬塞进步兵部队的历史泥潭.即使完全吞并中华民国也无法解决日本的问题，因为中华民国或多或少拥有与日本相同的资源库.虽然日本玩家可以在早期与美利坚合众国进行石油交易，但这束缚了民用工厂，而美利坚合众国早期的重点是禁运日本（他们可能会在历史焦点开启的情况下追求禁运）.

然而，日本很幸运，因为所有的橡胶和石油都是很短的船程，并且与盟军进行了一场战争.具体来说，游戏中最大的橡胶和石油供应可以在法属印度支那、英属马来西亚和荷属东印度群岛找到.虽然日本在与法国、联合王国或荷兰达成和平会议之前不会完全控制这些资源，但可用资源足以为飞机、轮船、坦克的建造以及日本在战争期间可能拥有的任何机动设计提供燃料.如果日本玩家不希望与盟军开战，他们将在 1936 年获得第一个允许合成炼油厂的技术，这为上述飞机、轮船和坦克的中等规模生产开辟了选择，而无需征服.在走这条路线时要记住的一件事是，合成炼油厂的建造极其昂贵和耗时，浪费了可用于建立其他军事和民用工厂的时间，这些工厂可以建立一支力量来获取日本实现其统治太平洋梦想所需的所有资源.

陆军

1936年,日本陆军由老兵和新兵共同组成。日本开局拥有45个步兵师，9个骑兵师，3支轻型坦克部队，2个摩托化师和一支海军陆战队。为了反映历史实际，日本军队开局时拥有2级经验等级和1级的武器装备（大概是想表现日本人装备不行，靠素质战斗）。这样的部队结合卢沟桥事变国策，允许玩家早在1936年就可以运用多种手段发动对华战争。日本也有一些部队仅列装了基础武器装备，这些部队主要胜任日本本土守卫和太平洋列岛的驻军任务。

日本军队模板的可选择名称如下：

山地步兵师 - Yamahei-dan Shidan
海军陆战队 - Tokubetsu Rikusentai 或 Rikusentai (海军步兵，而非陆战队）

策略和指南

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, the 美利坚合众国 and the 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 and 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:

初始征服选项

The Second Sino-Japanese War

Located to Japan's Southwest, 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 and 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 into a puppet as well as pressuring 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

傀儡印度

确保中国战场稳固后，可以向英属印度推进，这样拥有两个人力大国作为傀儡可以大幅减少本国人力损失。与中华民国不同的是，印度是联合王国的殖民地，这会卷入与同盟国的战争中。鉴于印度和中国都人多枪少，推荐双线入侵；一个是取道滇系和{flag|暹罗}}，同时海军入侵锡兰岛；另一条是取道喜马拉雅山脉直插印度腹地。不要给装备落后的印军喘息机会，但要提防盟军援助，这些可不是容易啃的骨头。

Oil Rush

Beyond India (the 英属印度) lies the fifth biggest oil producer in the world - 伊朗. Capturing it will secure twice as much oil as the 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. If the 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.

继续南下

在征服东南亚后，日本可以入侵澳大利亚与新西兰。此南下将极大的拓宽日本的海洋实力与并移除盟军在南太平洋的军事存在。两国都是欧洲列强的附属国，科技发达却人力短缺，进攻方式须权变：若卷入战争，因远征军故而本土空虚，宜速攻克之，否则强敌援至，不易登陆；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.
