Hi everyone, today's topic is something that has been requested in every diary thread for months, so here we go. its time to cover Japan.

Japan is a different and interesting nation to play in HOI4. They are effectively an island state like United Kingdom, but lacking its colonial empire to draw resources from. If Japan doesn't plan to reform towards democracy and settle with what they have they need to aggressively expand as early as possible and grab resources to fuel their war machine and build up their navy to be able to rival the other major nations.

When it comes to expansion routes there are several available, there was much debate and struggle in japan at the time which to go for. Nanshin-ron, The Southern Expansion Doctrine was supported by the imperial navy and involved expansion into southeast asia and pacific islands (bringing you into conflict with the european colonial masters and America). Its opposite Hokushin-ron, northern expansion was supported by the army and involved expansion into eastern soviet and siberia. Japan's focus tree tries to present these as different paths and also let you decide if you should favor army or navy focus.

Most of the diplomatic focuses for Japan require that you decide how to handle China. Its started by initiating the Chinese Border Incident focus where China is pressured into handing over border territory. Should they refuse Japan will get a war goal on them and can attack. Down this route japan may join Germany in the axis or establish its own faction before setting their aim on french indochina and Siam.

As nations go Japan is very different from the european powers, with its worship of the emperor, spiritualism and self sacrifice for the state. We wanted to make sure to capture this so Japan starts with the national spirit "State Shintoism" which make them more resistant to bombing and improves soldier morale. Their focus tree gets a pretty unique part called "Spiritual mobilization". It will both give more research options as well as improving the average soldiers morale, unlocking kamikaze missions, and if both research and warrior traditions tracks are completed unlock special rocket powered suicide crafts (MXY7 Ohka) which will be very hard to intercept due to their speed.

Japan has one of the world's most powerful navies and their air force is also strong. Their army is also pretty big, but in need of modernizing. Industry wise japan can get powerful but will struggle for resources if no successful expansions are done. As a japanese player you need to be careful with your fleet because naval battles can be very decisive and you do not have USA's powerful capability to quickly rebuild lost capital ships. Chances are if you lose your fleet you will not be able to recover from it in a war with the united states. Focus tree wise Japan can select bonuses to develop superheavy battleships faster and are able to unlock the unique Long Lance torpedo giving them greater range than other nations as well as research bonuses to carrier aircraft.

Historically japan did not develop their armored forces very far so we were faced with some problems when deciding on what should represent their tanks. Japan had plans for some heavier tanks which were never built (in the terrain they normally fight it heavy tanks do not make a lot of sense either), but you never know where a player may take japan of course.

See you next week when we will talk about diplomacy!

Any particular reason why Japan gets that extra research slot so early? If I recall it is 4th focus down the tree for Britain and even 5th for Germany. It should be vice versa.

Japan needs to focus on a lot of tech, I'd argue more than UK even, also from game balance perspective we want to make the fascist nations stronger early, so it makes sense to let them get it a bit earlier.

What resources (oil, rubber, steel, etc) does Japan start with? (Apart from not much, what are the numbers)?
What factories? Military/Civilian/Dockyard.

What National spirits, and what do they do?

And lastly, How many divisions, how many aircraft, how many ships of what type?

For the other majors this was all listed out as part of the DD.
I would like to have this, so I can do a comparison of the raw start conditions.

Very very cool DD @podcat !!! :) I got a few questions:

1st With how many BBs and CVs does Japan start in 1936?
2nd With how many military factories/dockyards/civilian factories does Japan start in 1936?
3rd What does the "Indian National Army" focus do?
4th Could we see the "Air Tech Tree" of Japan?
5th How come, that the Akagi Class and the Kaga Class are both level 1 tier ships? Is one of them a variant?
6th Which resources does Japan lack the most?
7th What does the "Subdue the Warlords" focus do?
8th Do you favor the "Northern Expansion" or the "Southern Expansion focus"?
9th How often does Japan end in a war with the U.S., if the do the Northern expansion focus? Did you have some experiences with that?

I know it's a lot of questions, but it would be cool, to know more about one or two of them!:)

Cheers:)

enjoy stats

PS: What is this "toaster" national spirit? I assume it's supposed to be coastal forts. A production bonus maybe? Or are they indeed toasters and will ensure a quick economic recovery after losing the war via bonus on small kitchen appliance production?

its the Imperial Austerity spirit. it reduces consumer goods need. We use toasters to symbolize civilian production. I did ask the artist to maek the toasters look nationalistic, but he hasnt gotten there yet ;)

Am I the only one who finds it strange to find 60ies tank - Type 61 in tech tree?
Its either that or making shit up from scratch, could have doen that also of course. The type 61 development started in like 1955 so its really the first MBT that fits for japan.

Type 61 fit way better than fantasy tank for a major.

yeah, france has the same issue really but I felt those models were too late to include directly. Luckily france has consistent naming for tanks, so its easy to insert invented variants that make sense and fits (italy has the same as well).

Not a word on Manchukuo, not even in a dev diary on Japan?

When will the developers finally answer questions on this matter or admit what everyone already knows: Manchukuo and probably also Mengjiang simply are not in the game and the reason for that is most likely to help the AI.

Yeah, its eaten by japan for AI reasons. fightign through puppet territory like that is really complicated for AI. They also werent doing much historically and whole thing was run by the Kwantung Army so we felt the tradeoff was worth it.
