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.

I feel that Japan needing to get nuked twice specifically is a bit too...specific. I also think the debuff Japan has against specifically Chinese troops could be handled better.

Elaborate?
 
Elaborate?
Just think that there are better ways to give China a backbone than giving Japan a debuff. They justify it by saying that the Japanese underestimated the Chinese, but I don't see Italy or Germany getting a debuff when facing off against Abyssinia or Russia. Its a clumsy effort to prop up China.

The two nukes thing just sounds silly; why are two nukes better than one? Why not three? II handled things better because it had dissent which would raise over time with strategic bombings or all at once with nukes, meaning events could fire forcing a surrender if dissent got high enough. It didn't require such specific conditions.
 
I've been around since the launch and this patch and down loadable is superior to anything you've done. Amazing amount of work and preparation and nice job not rushing it. I wanted it before Christmas of course but I think we're going to be super pleased when it does get launched.

Count me as impressed.
 
Will there be:
1. Banzai charge feature?
2. Kwantung 701st special unit?
3. IJA 23rd infantry division near Mongolian border for Khalkhiin-Gol incident in 1939?
4. Unrest in Outer Mongolia against communist regime backed by Inner Mongolians and Japanese Kwantung Army Intelligence Service and create Outer Mongolian japanese puppet in parallel to Mengkukuo and Manchukuo?
5. Kwantung army special elite units, divisions such as 7th and 23rd infantry divisions will be featured?
6. in 1939 at Khalkhiin gol, there were the largest ever Air Battles at easternmost Mongolian border between Soviet and Japanese Air Forces whoses number of aircrafts reached sometimes 1000 per battle. Will there be such concentration of aircrafts and air battle events whose outcomes give you air experience and bunch of ace pilots?
7. Nanjin massacre, that makes unite Chinese factions and worldwide infamy to Japanese Empire?

The Army (air corps, I refuse to call them USAAF, that term did not exist until after the war when the defense department was created and the USAF became an institution) had its own standards and the navy had its standards.
Wrong again. The USAAC officially became the USAAF on 20 JUN 1941 (before the US entry into the war), and the USAAC ceased to have any administrative structure on 9 MAR 1942. It remained the USAAF until 1947 when the USAF was created. So for the entire period of US involvement in WWII, it was the USAAF not the USAAC that controlled US Army Aviation.

I find this new surrender mechanic very funny, it makes me wonder if a dev by any chance read my AAR as Belgium, cause it would've been very useful if I had it back than :D.
 
I'm pretty sure the Sen-Toku's had a catapult capable of launching (but they definitely couldn't recover direct to the sub, and had a crane for that). Iirc, the seaplanes used were also a significant step up from the scout seaplanes used on other Japanese aircraft-carrying subs. Not commenting on whether they should or shouldn't be in the game.
I stand corrected. Not sure if I consider the Aichi M6A (with its armament of 1 torpedo or 1 850 pound bomb or 2 250 pound bombs) to be much of a step up from a real bomber, but it is a significant step up from its predecessor as a sub launched bomber, the Yokosuka E14Y 'Glen' (and its payload of 2 76 kg incendiary bombs)
 
Things that are missing in this patch:

I love the surrender button for Japan but we also need the peace button to work for all nations

The improve relation button is useless and needs more rework

An event should pop up when a foreign nation captures Berlin that Hitler committed suicide which lower NU

Colonial uprisings

Since this is a naval dlc, shouldn’t the uk be included ?
 
Its not only 1 condition with Japan surrender!

You surrender if :

- Have notting else Japan Island
-Nuked twice

I played 99% singelplayer game and there are lots of people who play only singel player. So its good to have historical condition in the game(like Fall of France). And for multiplayer : I guess you also lots the game when you lots China.
 
Wait, so there won't be a Manchukuo tree, after all? Aw, I was pretty hyped for the restoration of the Qing Empire.
I'm not seeing where you're getting that idea from. All it says is that there's a minor features DD next week. That doesn't rule out any other focus trees.
 
Does this mean you're changing around the Japanese cores? Because right now those islands Japan acquired in WWI are considered core territory.

Yes. It also helps with the industry focuses since you'll no longer build factories on some godforsaken Island in the South Pacific (funny though that was)

It's rather egregious that the Japanese unconditional surrender only really cares about how often mainland Japan has been nuked. The loss of Manchuria should, at the very least, be a requirement to take the decision. Soviet entry into the war propelled Japan to surrender more-so than the nuclear strikes.

Those are fair points made in this thread and we'll take another look at the requirements. I still think that the idea that one can just rush nukes is a bit overblown. Yes, you can probably game stuff but a) not in Multiplayer with a human Japan (and why should I care if you decide to game yourself in singleplayer?) and b) you essentially have to set up your game from day one to game the surrender of Japan.

is 'fate of the imperial family' a focus that gives you a pop up event choice about their fate, or a set result?

Event.

Will there be:
1. Banzai charge feature?
2. Kwantung 701st special unit?
3. IJA 23rd infantry division near Mongolian border for Khalkhiin-Gol incident in 1939?
4. Unrest in Outer Mongolia against communist regime backed by Inner Mongolians and Japanese Kwantung Army Intelligence Service and create Outer Mongolian japanese puppet in parallel to Mengkukuo and Manchukuo?
5. Kwantung army special elite units, divisions such as 7th and 23rd infantry divisions will be featured?

Will there be such concentration of aircrafts and air battle events whose outcomes give you air experience and bunch of ace pilots?
7. Nanjin massacre, that makes unite Chinese factions and worldwide infamy to Japanese Empire?

1. Already in the game as a special tactic for the Japanese. Some Japanese Generals also get a special trait (Samurai Lineage) that makes them more likely to use it. Japan also gets the "Desperate Defense" Command Ability at a lower cost if they research the right focuses.
2. We have no systems in place to simulate biological warfare and in any event that unit strays a bit too close to our "no Warcrimes" Policy.
3. We're working on using the new Border Conflict mechanic to represent Kalkin Gol a bit better.
4. Not at the moment
5. Not as such
6. See 3
7. No
 
@Archangel85:

Again, when seeing the more and more complex and also ahistorical options in the focus tree, can you please "mark" the "historical" path in some way to know what to choose if I want to play historical?

That would be great, thank you!!!

It didn't require such specific conditions.

I see problems with this on both sides.

The first is that i'm glad they are putting in historical decision about Japan's surrender, but in order for that to work there should also be requirement that they get completely pushed out of Manchuria, Korea, China and rest of mainland. Nukes at the moment are completely useless, there is no point of using them aside from spam bombing countries into oblivion until their national unity gets reduced when in fact nukes should be the main key factor that should decide the outcome of war in late game which is what is being added for Japan ( hopefully more countries in the future)

But the biggest problem when it comes to nukes is that they are way too easy to obtain and every single country is allowed to research them. I know HoI4 is going for the sandbox experience but if mechanics like these will come into play there really should be more restrictions.
 
Heisei 29 ends on Jan 8 because Akihito was crowned on that day, it has nothing to do with Chinese calendar.

Didn't read all of the thread yet, so apologies if this is already answered, but since the Meiji restoration (or at least the introduction of the Gregorian calendar during emperor Meiji's reign), imperial reign years still start on the 1st of January, unless it's the year of the crowning of the emperor, in which case the part before the crowning is eraX of the previous emperor's era, and the second part of the year is era 1 of the next, ending on the 31st of December.

So, 1/1/1989 - 7/1/1989 was Showa 64, 8/1/1989 - 31/12/1989 was Heisei one.

So Heisei 30 started on 1st of January 2018.

@Archangel85 please fix :p
 
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.

I don't like this.
Maybe Bicycle Battalions shoul'd be in support company to just give bonus to speed.

This can be a suggestion also for motorized infantry

Edit: Japan uses bikes only for transport, they didn't fight (shoot with gun) on bikes
