HoI 4 Dev Diary - Japan Rework

Hello, and welcome to the first dev diary of 2018!

Although considering today’s topic perhaps we should call it the first dev diary of the year Heisei 30.

When we decided to expand on China for Waking the Tiger, we also decided that we would need to take another look at the Japanese focus tree and maybe do some minor rework and some alt-history expansions. While we were basically happy with the existing German focus tree, we felt that Japan might need a somewhat more extensive rework, so we asked our QA to compile a list of issues they had with the existing tree.

QA noted the lack of flavor and interesting choices, as well as the lack of really unique gameplay. Their final recommendation was fairly short:

Burn it down. All of it.

So we did.

As you can see, we have expanded the focus tree somewhat in comparison to the old one. The choice between striking north or south was a single focus each in the old tree, but has now been expanded into a full branch.

The first basic choice is what to do with the Kodoha (“Imperial Way”) faction in the military. This faction wanted to remove the last remnants of civilian government and restore the Emperor to his rightful place (i.e. a figurehead while the military has the actual power, as things were before the Meiji Restoration of the 19th century). Historically, supporters of this faction launched a coup in February of 1936 which failed within days as the rest of the military refused to support it.

For reasons of transparency and playability, we decided to not have the coup be an event that fires on or around a set date but made the choice of whether to support or purge the Kodoha faction part of the focus tree. Purging the faction sends you down the historical path to attack China, strike south and attempt to seize the European colonies for their resources.

As you can see, we decided to make Japan form its own faction in the historical path instead of having them join the Axis. The cooperation between Japan and Germany does not fit neatly into our current faction system. While Japan did join the Tripartite Pact, it did not join the war against the Soviet Union, and indeed the Germans concealed preparations to attack the Soviet Union from their Asian allies. While there was some military cooperation and exchange of technical know-how, it wasn’t anything like the scale to which the Western Allies cooperated and indeed closer to the military cooperation between the Western Allies and the Soviet Union.

Still, it is a historical fact that Japan joined the Tripartite Pact, and as such you can do so in the historical path. But instead of joining the Axis faction, it creates a set of mutual guarantees between Germany, Italy and Japan. Should either of them be attacked instead of being the aggressor, they can be called into each other’s wars (and frankly, that is a lot closer to the relevant Article 4 of the treaty).

While still not perfect, we believe that this solves more problems than it creates. In particular, it means that Germany isn’t considered to still be fighting until Japan is taken (which led to amusing side effects such as the Luftwaffe forming the Legion Pekingente and evacuating to Japan when Germany falls). Speaking of taking Japan: AI Japan will now surrender if they have been nuked twice or lost Manchuria and Korea when they aren’t holding any territory in China. A player has the option through the same decision but can, of course, choose to fight to the bitter end (the AI is simply scripted to always pick the decision as soon as possible).

Simulating the war in China itself has come with its own challenges. We wanted to make the war feel like the long campaign it was (lasting, historically, from 1937 to 1945), not least because a Japan with a secure China can bring far more resources to bear on other targets than it did historically. At the same time, China starts with crippling penalties to its army, which means that Japan could easily defeat them. This is not particularly historical, as the Japanese expected a quick victory and were rudely surprised as the Chinese divisions fought very tenaciously.

So in order to make the campaign in China feel historical and give the Chinese player a chance to survive the initial invasion, we gave Japan some penalties for fighting in China (or, specifically, when fighting against Chinese troops). These penalties can be reduced through decisions, which raise world tension, so you will have to balance out the need to finish the campaign fast against raising world tension too quickly. We feel that this best represents the disdain the Japanese military held their opponents in - the Chinese simply weren’t worth a proper effort. Of course you, as the player, can hound your military into actually taking this conflict seriously, but the rest of the world may not like the idea of all-out warfare in China.

If you decide to side with the Kodoha faction, you effectively decide to strike north against the Soviet Union (as many in the Kodoha faction believed that the Soviets were the bigger threat). Subsequently, you will have to do some diplomatic maneuvering to keep your southern flank secure: Where historically the Japanese signed a Non-Aggression Pact with the Soviet Union while they were engaged in China (at least in part because the Battle of Kalkin Gol revealed some serious shortcomings in the Japanese military) to secure their northern flank, now you will have to sit down with the Western powers to ensure they will stay out of your hair while you deal with the Soviet Union. The London Naval Treaty reduces your dockyard output quite dramatically, but should serve to keep the Allies happy enough to look the other way when you go to war with the Communists. You will also have to send some equipment to your Manchurian “ally” to enable them to actually be somewhat useful in the war.

Later on, you can join a technological exchange program with Germany and even gain access to German Rocketry. Going down this path will also allow you to prospect for resources in Siberia.

But of course, you don’t need to follow history quite so closely. The democratic branch assumes that there could have been a significant pushback against the militarization of Japan from forces inside the civilian government. After all, Japan did have a functioning system of democratic elections and a working parliament during the Taisho period, a mere 10 years before the start of the game.

However, the militarists will not go quietly and will rather flee to Manchukuo than to surrender their position. Those elements of the army that can’t or won’t go abroad will start a civil war. Once that has been dealt with, you can rewrite the constitution to turn the Emperor into more of a constitutional monarch like the Europeans have. Afterwards, you can either try to reach out to the British and revive the Anglo-Japanese Alliance that has served so well during the beginning of the 20th century, or you can form your own West Pacific Treaty Organization (or WPTO).

But that still leaves the problem of Manchukuo, now firmly run by the Kwantung Army and supported by the very militarists you kicked out of the country. You will have to go and remove this threat to your freedom with some good old fashioned liberty bombs. From there, you can go and ensure that the colonial powers actually make good on their promises of freedom and self-determination for the native people. After all, if you can have a functioning democracy, why can’t the rest of Asia?

Finally, there is the communist branch, which is not quite as far fetched as it may seem. Historically, Japan experienced the same rise of leftist agitation as the rest of the world, and the Japanese Communist Party enjoyed some successes until new legislation effectively banned it. Extensive measures by secret police agencies ensured that by 1936, the party posed little threat to the establishment. That, however, does not mean that there wasn’t a potential for a revolution. A large number of young officers came from a peasant or working-class background, and many civil servants considered socialism to be the way of the future (or in any event better than the Japanese form of capitalism dominated by the huge industrial conglomerates, the Zaibatsus).

hoi4_102.jpg


Historically, these civil servants were quickly banished to Manchukuo or “encouraged” by the secret police to reconsider their political stance. The first step towards a communist revolution in Japan, therefore, is to recall those civil servants that have kept the faith back to the homeland as well as sending a number of militarist hardliners to serve in Manchukuo instead. By arranging for a number of younger and more revolutionary minded officers to be promoted, you will also gain three very loyal and reasonably capable Generals who will definitely serve on your side in the unlikely event that a civil war should break out.

In the next step, you trigger a civil war.

Here, the decision to send the militarists to Manchukuo is both a blessing and a curse, as the Japanese holdings in China are taken over by loyalist troops - who are nonetheless unable to interfere in the civil war in the homelands. Once you have secured the Home Islands, you face another problem: The Emperor has been the foundation of Japan’s political system for thousands of years, and you have just deposed him. Your government has very little legitimacy in the eyes of the people, so you will have to rebuild their trust and stabilize the country. Only then can you go over to the Asian mainland and eradicate the pest of militarism before making common cause with either the Soviets or the Chinese Communists.

The Japanese military was famous for the poor relations between the Imperial Army and the Imperial Navy (for example, it took the Navy until 1943 to confess that the Battle of Midway hadn’t gone exactly as planned and had in fact included a minor setback). In the game, this is represented by a number of decisions about the prioritization of resources and resolving conflicts between the two parties. Each decision affects a national spirit representing the balance of power between Army and Navy, which affects things like factory output and dockyard construction speed.

Finally, as part of the rework, we decided to give Japan a bit more flavor by adding two units that are currently unique to Japan: Bicycle Battalions and Torpedo Cruisers. The former are about what you’d expect: infantry mounted on bicycles move a little faster than regular infantry but require some more resources. Although they are currently restricted to just Japan, they might end up being accessible for the rest of the world if we can find a place to put them in the tech tree. The Torpedo Cruisers were a fad in the Japanese Navy, who refitted a number of light cruisers with no less than 40 torpedo tubes (20 per broadside). Together with the Japanese bonuses to torpedo range, they can become a very terrifying force on the high seas - if you can manage to lure the enemy into a decisive surface battle.

In the process, we also fixed a small issue that pestered some fans of Japanese aviation:

Similar to the German focus tree, parts of the new focus tree will be part of the Waking the Tiger DLC. While most of the new focuses are free, the communist and democratic branches of the political part will be paid.

We will continue to rework vanilla focus trees in future DLCs (assuming, of course, that this meets with approval from the community), with an eye to which countries make sense with the overall theme of that DLC (for example, reworking the Soviet Union doesn’t really fit into a naval-focused DLC). Expect further updates on future plans after the release of Waking the Tiger.

DLC focus trees will see occasional updates when necessary to accommodate new mechanics (for example, Hungary now inherits Austria’s generals if they manage to form Austria-Hungary) but probably won’t see major reworks.

That is all for today. Tune in next week, when we open up Bag of Tricks #3. There is no World War Wednesday stream today, but it will be returning next week as normal.

... did they field entire battalions of motorcycles, or were the motorcycles assigned to various levels throughout the army? Because I'm pretty sure it was the latter.

It was both. The Germans did have complete motorcycle battalions in their divisions.
 
@Nicolas I , did they field entire battalions of motorcycles, or were the motorcycles assigned to various levels throughout the army? Because I'm pretty sure it was the latter.

You are partly right.

These reconnaissance units (Aufklärungsableitung) were at first (1939-41) motorcycle battalions attached to motorized and panzer divisions (as I said).

Later during the war (1942+) they were mixed with Kübelwagens (not much more expensive than a side-car but carrying 4-5 soldiers), half-tracks and/or light armoured cars, heavy armoured cars and even some light tanks as the concept of reconnaissance in force evolved. The fact that motorcycle units had great difficulty coping with the poor terrain in Russia or North Africa (as opposed to Northern Europe good road networks) and mounting losses was another reason to amalgamate the motorcycle battalions with divisional reconnaissance battalions. The progressive replacement of motorcycles enhanced both the survivability and firepower of the battalions.

As you thought, eventually these motorcycle units would rarely operate as whole companies, and instead worked in mixed teams gathered from various units.

Thanks for making me search quite a bit to clarify this subject.
 
An event with Japan surrendering without a mainland invasion was sorely needed, considering how it was always necessary before. It's not great when the game forces an alt-history scenario.

Agreed, but I think normal mechanics should allow for it to happen naturally.

The first few uses of the atomic bomb should come as a major shock to a nation already losing a war. I think nuking the UK, Germans, USA, etc into surrender should be just as valid as the historical route for nuking Japan. It's just that, after the world has weathered the initial shock of the superweapon, then the atomic bomb's ability to shock the world's nations into surrender would be greatly diminished. One might start gaining the world's ire if you kept using them, too.

HOI4 shouldn't replicate a complete cold war scenario, but it could at least give mechanics for things like Operation Unthinkable; where A-Bombs would have possibly been used in relatively large quantities. The effectiveness of superweapons on quickly ending wars should change over time, as they become the 'new normal'.
 
Will there be also an Italian Rework?

They have previously stated that they'd like to get around to revising every major nation at some point, but they're doing them in waves. This patch is getting GER+JAP, there are 7 majors, so it will probably take 2 more expansions before every major has been re-touched. It might be more, or less, but I'd guess 2.
 
Dear developers, please fix the "BIG MESS" with island names. (From Chile to New Zeland)

example:

"Pitcairn Isle" (ENG) it should be "Isla de Pascua" or "Rapani" or "Easter Isle" (CHL)

Pitcairn isle is more at east

and much much more....

Kind regards

That's where you're wrong about communism. They're supposed to be the proletariat first and then any national identity is just left over social construct from before the revolution which will eventually be re-educated out of the masses consciousness. There can be no national identity since communism is international. National identities are spooks and reactionary sentiments used by the bourgeoisie capitalists to divide the working class. This is what communists actually believe. This is also why they often exterminate huge swathes of the former ruling class of the society that they are trying to take over.

I'm not one of them but, that is their position. The Emperor would be a symbol of eternal Japanese national identity, pride and spirit and those things get in the way of the global worker's revolution.

This is in spite of the fact that many self identifying Socialist and Communist groups have used fierce Nationalism, bigotry and reactionary sentiments to reach their goals and appeal to the masses such as the DPRK, the Soviet Union (especially under Stalin), Yugoslavia and the People's Republic of China. Of course this opens a whole can of worms and definitions of what is real communism and/or socialism and have those countries actually achieved the state of real communism and/or socialism (they never did but, its irrelevant as far as real world politics is concerned). Anyways never expect a communist to be internally consistent with his or her own world view. Communism can best be understood as a malleable ideology with general appeal to the masses of the lower class which small cliques of the party leaders use to gain enormous power for themselves, rather than thinking of it as any kind of coherent and internally consistent world view (when put into practice).

Suffice it to say that it is highly unlikely that any communist groups that gained power in Japan that are similar to the Marxist-Leninist schools of thought would allow the Emperor to have any power what so ever, let alone live at all.

You're (partly) describing Bolshevism and, more specifically, Trotskyism (and even then, it's basically proto-Trotskyism, before he decided that the USSR - as the USSR - should spread communism by the sword, with the Vanguard concept shifting from a popular movement to a state-level apparatus). It is about as accurate to use that as a broad brush as it would be to use Neo-Conservative philosophy or Objectivism as a broad brush for all capitalist & liberal democratic systems.

None of the Japanese socialists believed that (...Hell, most socialists at the time period didn't believe that, not even in the Soviet Union, which is why Trotsky lost his support and was forced into exile while the Stalin counter-revolution took root).


It is probably fair to say that the imperial family would not have survived a communist revolt & that much of the nobility would suffered the same fate as the aristocrats & land owners in Communist China after Mao realized his manifest destiny, but it's a bit silly & partisan to say that the revenge killings & assassinations came with only through high minded philosophy. It is easy for a popular movement to tilt into raw populism, and there is nothing that will win you the hearts & minds of a raging mob like stringing-up the former agents of the establishment (Ahem. 'Lock Her Up!'), however worthy or not they were of execution. The same thing happened in France, and the same thing probably would've happened in America except that an ocean separated the angry mob from the aristocrats in England (and even then, in the stead of the nobility, Patriots settled for killing Loyalist settlers & their families).

Rather than ascribe the failings of socialist movements in the 30s and the atrocities that followed to Lenin's early philosophical writings or Marx's body of work, I think we are much better served to recognize that violent revolts of any nature are easily co-opted by people whose goals are mostly personal, that being a high minded Washington is incredibly rare and probably contingent on equally rare circumstances & that the temptation to declare oneself as They Who Knows Best after leading a successful revolt is too great to be resisted - regardless of one's political stripes or belief system - by the overwhelming majority of people.
 
"Girls und Schwerpunktbäume" would have been the best name for this! Sadly it was rejected. :(

The moment, I realize how ugly my native language can be. "Schwerpunktbäume" ... How should I explain that to an English speaking person? o_O

Focus Tree? But yes 'Schwerpunktbäume' is such a typical German word...

Which brings me back to that can of worms and definitions that I was talking about. The game calls them communists as well as many of those own groups self identified as communists but, none of them ever actually were real communists nor has any society in history ever actually achieved communism since they never achieved a classless, moneyless, stateless "society". I'd say it actually would be pretty accurate to describe all liberal capitalistic democracies (that are important on the world stage) as the same as the NeoCons.

I miss the political categories the previous games had.
