Strategy Guide for Starting With Japan

Hi all – this is my first post here, and I wanted to write a small strategy guide for getting started with Japan that could help fellow newbies learn the game. It took quite a while to do so I really hope it’s helpful to someone.

I am new to the HOI series and I found Japan 1936 to be a great way to learn the game – you fight an early war with China, you get a good sampling of land, air and sea units, and you have enough industry and leadership points to experiment with, but not so many that you’re overwhelmed. So here are some tips I developed after playing three separate games as Japan. (note: my focus is on just playing the first 2 or 3 years to learn the game and experiment – you might do things a bit different if you’re planning on long-term war with the USA)

Starting Off (Early 1936)

Early Japan Objectives: Your first main objective should be the conquest of China. You’ll get the option of the Marco Polo Bridge Incident on Jan. 1, 1937 which will begin the war. Your first targets will be Shanxi, the country bordering your puppet Manchukuo, and Nationalist China. Let’s start with an overview of your situation.

Your Army: You have a decent-sized army to begin with, but they’re all spread out. You need to shuffle them around so they’re ready for the war. After a long and painful reorganization of the HQs hierarchy, I moved/transported all the infantry, cavalry and one motorized infantry from the Japan mainland, Korea, and Russian border, down to the border with Shanxi. Keep the folks in Taiwan where they are, sometimes Nationalist China tries to invade.

Your Navy: You have a big navy, including 3 carriers and one escort carrier, allowing you a total of 7 CAGs. I reorganized them all and made 7 fleets, 3 of which were carrier groups, 3 were transports fleets with lots of escorts, and another was a submarine fleet (don’t include subs or destroyers with your carrier group as they severely limit their range of operations). I sent the sub fleet to defend Taiwan.

Your Air Force: You start with several tactical bombers, 4 fighters and a naval bomber or two. Rebase all your air units to the Manchukuo airbase closest to Shanxi.

Resources: You’ll need to do a little bit of trading to keep your resource stockpile in check, especially when your IC rises with war economy in 1937. Trade with any of the big nations for about 75 – 100 Energy, and maybe a little bit of Rare Materials. Don’t worry that your oil goes to 0, Energy will keep converting so your Fuel stays fine.

Diplomacy: Not much to do here early on other than make those trades you need.

Production: Other countries can focus on Industrial Capacity in the early years. With Japan, however, you need to prepare for war immediately. You’re going to need a lot more divisions, especially considering the huge West-to-East front you’ll fight on across China. Once I pushed into Nationalist China, both our armies usually only had one or two divisions per province. Because of this, it might be wise to just mass produce Infantry divisions so you can have several divisions per province. But if you’re new like I am, you probably want to experiment with tanks. In my second game, in the run-up to 1937, I built 2 divisions of 2 Light Armor-2 Infantry (for the combined arms bonus), and I think 4 divisions of 3 Infantry brigades each. You also need to begin building naval ports which, once you invade China, you can place in your captured territory to help get supplies to your troops. I built 3. You also have room for another CAG on your Escort Carrier.

Technology: You’re going to be fighting the Chinese in a year, so you need to immediately begin researching techs to help win the war: techs that improve your infantry, light armor and especially supply. Begin researching the Infantry techs, even if the soft attack one is a year or two ahead of time – your ability to kill other infantry divisions will make all the difference (you can skip the one that increases their Hard Attack, as you won’t be facing any Chinese tanks). Any of the land theories that increase their organization is helpful. Research all the Light Armor to make some really tough LA divisions. Supply is going to be a big problem, so prioritize the techs in the Theory and Land Theory tabs that help with supply. I also did the education tech, and a couple more in the industry tab that improves IC and research times. Add infantry and automotive theory too.

As for the leadership points, you need to put about 6-7 into officers in order to keep up with your new units. You don’t really need any diplomacy points, and can ignore espionage if you wish.

Politics: Update all your laws to the most efficient – you can even start with the second-best mobilization laws since your neutrality is so low. I kept the training level at the 20% exp. level because I needed more units to cover the Chinese front. Not much to do with ministers, but check back when it turns 1937 – there’s a new guy who can give you +5% leadership.

Espionage: For internal spies, raise your national unity until it hits 80% so you can get the best industry law, which helps with supply throughput I believe. As for other countries, you may want to invest a little bit into lowering Nationalist China’s unity so they surrender sooner.


War!!!

Historically, the Marco Polo Bridge Incident didn’t happen until July, but each of the three times I played I couldn’t wait, and attacked in January. Waiting may be better so you can build more units.

I tried out 3 different strategies in each time I played, finally getting it right on the 3rd time when I was able to defeat and annex all of Nationalist China by mid-August. Here’s my suggestions from my experience:

The Shanxi Front:
To quickly defeat Shanxi, you need to capture 3 of their Victory Point provinces, the first two obviously being the ones closest to your border (see map below).

Japan1.jpg


The Eastern Front: You should easily push into Shanxi by 2 or 3 provinces all along the eastern front within the first week. Their divisions on the border won’t be fully mobilized and will be defeated very quickly. Don’t get too confident, because the rest of the Shanxi army in the south/west will redeploy toward your advance. After I got about 2 or 3 provinces in, our forces were about evenly matched and the front line remained static until my divisions up north were able to advance and hit their flank from the northwest. Also, make sure you take the lone Shanxi port – this will help bring in supplies from the mainland.

The Northern Front: The Shanxi provinces in the north are mostly mountainous. In my first game I attacked these head on with several divisions and got bogged down for a month despite stronger numbers. In my other games I left only one division per province (see the blue line) in order to contain the 6 or 7 divisions they had in three provinces up there. Your terrain along the border also has hills/forests, and they never attacked me. Keep an eye for opportunities, however, as in my third game they left the two provinces to the south of Arpinium Sum (the second from top province of theirs) open for a few days and I quickly sent in a cavalry and infantry division in, cutting 6 Shanxi infantry divisions off from their supply chain. After 2 weeks they were out of supplies and I attacked from 5 different provinces, completely destroying them in a few days.

In attempts of getting a quick surrender, I put all my cavalry and one motorized division together to race toward the VP province in the west. In two games this worked, and I found an opening where I sent a cavalry division through undefended enemy territory to take the VP province.


The Nationalist China Front:

Once you push down through Shanxi, you’ll be facing most of the Nationalist Army to the east. It’s best to open up a second front against them by invading them through their northernmost port. The map below shows what happened during my second game. There I invaded with some newly built light armor-infantry divisions, a cavalry division and several infantry divisions. Doing this forced the Nationalist army to head both to the northeast and northwest. I pushed west and south with my invasion force until they were too spread out to advance any further, and waited until the Shanxi front came further south. To help combine the fronts, some newly built light armor and infantry divisions in March were transported to the captured Shanxi port and fought their way south.

Japan2.jpg


All of these actions were supported by the air force. Bombers assisted with the invasion and general weakening of the Nationalists along my front. I also sent the 1st Fleet, which had a carrier and the escort carrier down by Taiwan. Their 3 CAGs did bombings of the Nationalists’ industry to weaken their ability to send reinforcements.

The Communist China Front:

Once the Shanxi fall after about a month of fighting, you’ll quickly face the Communists. I would suggest annexing Shanxi rather than puppeting, as your supplies won’t travel through them for some reason (as of 1.1c anyway). They also didn’t declare war on the other Chinese countries (shouldn’t your puppets declare war on your enemies?). When you do annex them, this sets off a rush for Shanxi’s southwest provinces. Your army will only be about halfway into Shanxi, so you’ll inevitably lose several newly annexed provinces. The Communists have quite a few infantry divisions, so the key to victory is choosing where to fight. I set up my front in provinces with mountains and forests, and allowed them to advance to neighboring plains. I kept a few places in the forests weak so they would attack, then brought in divisions behind my line to reinforce and win the battles. Once they give up on their attack and their organization is low, launch your own, hitting them in their provinces that give no defensive bonus. After their first retreat, you should be able to push on and capture their capital relatively easily.

Supply Problems:

In my second game, after defeating the Communists, I easily advanced south and took wide swaths of Nationalist land. However, come July, everything came to a stop because my supply lines were all red. Infrastructure is terrible in China, so you can’t expand your front line indefinitely. Look at the picture above and you’ll see my mistake. I took the picture with the Resources map mode to highlight how I had taken tons of worthless land in China’s interior, while failing to advance on her more valuable provinces in the east. To avoid devastating supply problems, focus your advance on the east. It may be tempting to plunge to the southwest when the Nationalists fail to defend that flank, but there’s a reason their stronger units are out east. If you have problems advancing there, send in an invasion group into Shanghai, and push north toward their capital. Taking that will get them close to surrender – send your cavalry units into the interior to quickly capture more VP provinces.


Good lord, I can’t believe I wrote this much … if you read it all, kudos to you, otherwise just looking at the pretty pictures are good enough.

Reactions:
Very interesting write up. Can you build mountain divisions as Japan in '36? They might be a better alternative to light armor as "elite" units which could help you fighting through the rough terrain in the far north and south. At least, they were quite good for this purpose in HOI2.
 
Someone should stick this in the Wiki. Not me, I'm going to bed now.

By the way, what did you use to make this? Photoshop or something else?
 
You can't build Mountain Infantry as Japan right off the bat, but it looks like you could probably research and then produce them by the time you were ready attack the Guangxi Clique in the mountainous south.

And I just used simple Microsoft Word for the maps. You can do a lot with the shapes and text boxes.
 
couple of things ...

1)
you dont need regular infantry to fill the gaps in your line as japan.
militia will do the trick aswell and you can use them afterwards for occupation duty. if you build up a big force in '36 it will somewhat slowdown your development once your done with china cause youll have to supply all those troops AND once you move against the UK wills till need some occupation forces in china to deal with the uprisings.
so imo, stick with your starting army, build a few inf divisions and fill the gap with militia
2)
researching techs that are 1-2 years ahead is BAD. depending on your theoretical you could research up to 3techs with the proper year in this time. best choice is to focus on 2 things. first one is naval techs, ships take forever to build and the earlier you get to the newer models the better. second is regular infantry tech with militia and artillery thrown in. that will get you through this war quite nicely. once china is done focus a little more on industry.
also, keep in mind that researching works best if you concentrate your efforts in specific areas for some time due to the increased buildup of theoretical.
3)
there really is no need to advance on a broad front, spearhead attacks on the VP provinces are the way to go. when i conquer china there are usually a lot of chinese occupied provinces left, you only need to stall these forces(militia comes in handy here) until you reach the VP provinces with fast advancing cavalry.
4)
armor ... pointless at this point, invest in cavalry, your tech is a lot further advanced in that sector plus its cheaper and does the job just aswell. the chinese army is a joke when it comes to fighting anyway, you dont need tanks to break through so the only real bonus armor has is the speed...but as i said, you can use cavalry for that.
furthermore, once you move against britain and the US armor becomes even more pointless. against US in the pacific its gonna be island hopping and fighting in jungle and mountain areas, armor is no good there.
against britain you have to advance through mountains and jungle again. and once you get past that and reach india their army will most likely be broken anyway, so armor again, is wasted.
only good reason for japan to build armor is when you start considering an invasion of the US mainland.
 
Nice writing and very nicely made pictures. (I could imagine a nice AAR later, maybe after the patch?)

In HOI2 I played out this situation a lot, with different tactics, in most of his points I agree with TheJoker. I really looking forward to see these familiar places again, but won't try this until the patch arrives. Meanwhile, waiting for the box...
 
An excellent introductory guide! Well done! I hope this makes it's way into the wiki! :)
 
I have to disagree with most of what you wrote.

- First and most importantly you don't need extra troops to take out China. Nat. China is a joke right now and your only real opposition is Communist China who have a lot of divisions. All I used were the starting troops in Manchuria and Korea minus the garrison forces in those areas. I only shipped two divisions in from the mainland (the Imperial Guards). I was through Shanxi in a week and in six months the war was over.

- I did build extra divisions, nine of them to be exact but I used all of those further south to perform a largely unopposed landing at Shanghai and take Nanjing. Communist China forced me back over the course of a few months but only a few provinces but that caused their strong forces to be strung out more and I eventually was able to cut their force in two and destroy it piecemeal.

My advice for the playing Japan is as follows.


Industry Since you need to import so much of your resources you need to build a lot of consumer goods to get the money you need so your IC is going to be limited. Focus your industry first on getting your units upgraded. After this is done build some extra high quality units. I build motorized infantry with armoured cars attached but you can pick your own divisions.

Forces You have enough units to complete the invasion as is so don't ship your newly build units to China just yet keep them in reserve. The supply lines can't handle them anyway. Organize the units in Manchuria in coherent Corps and I would advise getting all your cavalry in a single assault force or distribute them across the front as reserve forces to feed them into where ever you need them as a rapid reaction force. Cavalry are better than they were in HoI2. I agree that armoured forces are costly and useless in China. I hate militia and would never recommend anyone building them. As I have said before and will again, you have enough troops and when fighting outnumbered you need high quality troops not second stringers filled from the class of 1875 and boys who have not even graduated yet. It even means you need to focus on yet another research tree. Don't use them. Use your cavalry after the war as garrison troops.

Research I would advise focusing on industry techs first. You can lower your Energy use by over 60 per day with the first coal to oil tech alone. Get the 1918 techs at least. Also increasing your industry output and of course leadership (that is a given for anyone). Increase the supply throughput and decrease the loss rate. After this focus on infantry and land doctrines lowering the time between assaults and increasing organization of your units. You have plenty of leadership so this shouldn't be a problem.

Additional research in cavalry will actually make them slower so be mindful of how much you invest in here, your cavalry are already quite potent and don't need the firepower.

Don't forget to invest in your own spies to get foreign spies out of Japan. Btw I never planned on playing this all the way to end, it was a one night game with a friend but getting more Navy tech early if you do plan on playing on sounds like a good idea.

Battles Most importantly don't panic. You are going to be fighting outnumbered but your forces can handle it. Shanxi is a pushover. Take the port in your opening move and annex when able. This gives you a good supply situation for pushing on. You are going to start with a complete front but don't strive to hold every province on the front line with units. You can afford to have some gaps when losing those provinces doesn't hurt you. Keep an eye on your own flanks though, the AI loves to cut your supply lines and that is some thing you wont like.

Once you reach Communist Chinese borders they will start their advance and they will push you back. Don't worry, fall back slowly and only where you need. They are going to lose their advantage that way (their numbers). Feed reinforcements into this battle as needed and build up on their flanks. Once they have advanced far enough cut them in the middle and destroy the exposed forces. With the bulk of their forces gone you can easily take the country.

During this I also landed my newly build forces around Shanghai landing one unit to the North and invading with another. My plan was to cause a diversion by threatening the capital while the bulk of my forces were deployed on the communist front and the rest were under threat from being overrun. As it turned out the Nationalist don't have enough forces to be a real threat, after the communist where destroyed I could simply advance my motorized infantry to the new capital of the Nationalist and they surrendered soon after.

One last tip. Seize the ports. You need them for your supplies. I had one division out of supply most of the time but always a different one and never for long. I give the credit for that to not using to many forces and going after the ports as a priority.
 
Couple of notes:
I think you make mistake to overconcentrate on Chinese. True you have to deal with them early but there are bigger things to come so you should have that in mind.

Your main goal is to get access to resources your economy needs. And for those you have to fight European colonial powers, sooner or later. For there is no oil in China.

Oil and rares are also the first thing you should deal when you start. Trading coal (energy) is really bad use of your money for coal is converted in to oil on very bad rate. You should trade for oil instead. Once your oil is in green, coal to oil conversion stops and you will get coal in green numbers too.

Therefore I manage few trades with Asian countries for rares and oil. Those include Siam, Turkey, Saudis and Persia. This should cover your rares need. For oil however you have still to trade across sea. You can get it from Venezuela and USA.

Generally I want surplus in all my resources since I wan to build some reserve while I still can.

Establishing trades have relation benefits so I make trades with countries I wish to have good relations. Most important ones are USA and USSR. The second as back up trade partner if war with USA kicks. USSR will not trade oil but you can get some rares and fuel. You can manage to sell them some supplies too.
For this trading for friendship to work best, you should establish many small trades, not one big one. And you will need some more transports so transport fleets are first thing I produce. I usually need to build 5 of them in longer run. You also need some diplomats so you have to invest your leadership there. I thing about 0.5 should be enough.

This "economy first" policy is mirrored in my research priorities. I research all economy relates techs as priority to up to date standard and keep it there (including education and agriculture).

Next thing to do is rearrange your internal policy. You should pick policies which lets you manage your economy and leadership most efectively. Therefore I mobilize my economy (giving you 100% resources), take 2 year draft(more officers) and set education to more advanced one (10% leadership)

That should set your economy on foot. Once done I look at international policy and set my long range goals there.

I want to keep USA away from Allies as long as possible, so I recall my spies from Asia and send them to Britain and France to raise threat. Once other countries will join I send spies there as well. Most valuable in this respect is Canada as it is USA neighbour. If I can spare some spies I rise threat of Comintern and Holand too. There is no need to deal with China since you will soon get Marco Polo Bridge incident by which you can declare war on them.

However I want to have freedom of war declaration in the future so I set my internal spies to lower neutrality and get as much of them as possible. You however will need to switch them to counter-espionage from time to time as other countries will target you as well. Particulary deadly are their efforts to interfere with your research (you can find out in research screen on tooltip if they do).

Only when all this is done I start to worry about China. Your worst enemy you are going to fight there is gona be undeveloped infrastructure which will cause supply nightmare. Therefore I research supply throughput as much as I can.

I rearrange my army in Manchuria by sending all combat units to border with Shanxi (North China Exp. Army) and setting HQ structure by including Corps level. I do not send more troops there since my supply will not be able to support them anyway. Instead I build second invasion force in Japan. Normaly I build one more mixed brigade and use 4 mech. brigades (one in Formosa) to form two light mech. divisions. I build two light armor brigades for each. I add few triangular infantry divisions and scrap Home Isles for others to create 2-3 corps South China Exp. Army. Two infantry divisions in Formosa should stay there to defend island.

I rearrange my 3 fleet carriers and some support and screens in to one Kido Butai, make one bombardment fleet from few battle cruisers, arrange transports in to few transport fleets and split subs in to fleets, two pieces each. This force will support my army in China later.

All tactical bombers are send to China with all but one fighter wing. That one will be stationed to Formosa with both naval bomber wings I have.

These arrangements have time since Marco Polo Bridge Inc. will kick only in 1937. I also suggest to wait with war till later months of that year since it will give you more time to prepare. I spent that time with arranging trades, researching, building resource reserves and keeping balance on bank account. You will need money for trading so usually there is not room for massive production. Your forces are also quit obsolete at the start so you need to invest heavily to upgrades. Therefore I produce only units I gona use in China and some supply transport fleets.

Once war is declared my strategy is to quickly kick Shanxi out of war. By time you accomplish that you are probably out of supply so I make tactical withdrawal back to Manchurian borders but keeping control around Shanxi port and dig in there for defence. This suits my next move as well since it will draw Chinese forces north.

Once they are there I make two landings in both National. China ports with my South China Exp. Army and its corps which were sitting idle in Home Islands meanwhile. I use my navy to support them. Once both ports are in my hands I try to link them, then link with North China Exp. Army to create continuous front. With 3 ports supply of my troops should improve enough that I can mount all out attack on Chinese with first goal to kick Comunist Chinese out of war since they present biggest threat. Once done, situation should be under your control and dealing with rest of the Chinese forces should not be problem.

During fighting on land I send my subs to hunt for Chinese convoys and build few border guards units to keep Chinese ports secure from partisans and few combat units to boost battle in China. Preferably Marines which should be researched by that time -you will need them when China war is over and there will be bigger game to hunt :)

I almost never worry about china. you need to focus on the resource rich colonial powers in the south. At worst you will loose a puppet and korea but an early war into netherlands before they join allies will set you up. then turn to the USA late 37 or 38, take hawaii and then california. split your naval forces for transport and hunter/killer CAGs, once you find the USA CAG you will most likely crush it and they won't send over the norfolk fleet.

use non upgraded calvary to quick march east, your goal is the the north east from washington north but you can really take all the VPs you want, USA won't join the allies and surrenders once you get into the NY area. Once it's yours pump out garrison and occupy. set it up to exploit. you will have tons of IC and manpower by 1941 and can move on the british isles or if you like push overs use marines to take SA.
 
Thanks for all the great feedback! I certainly agree with people who say to be thinking about the allies long-term - as I mentioned, I was using Japan more as a way to experiment with different units so I had enough confidence to play as some of the other powers. Had I been doing otherwise, I may have started building IC instead and probably would have ignored armor.

Though even with the extra infantry divisions and whatnot, in my third playthrough I managed to keep supplies in the green in China by placing 4 or 5 new naval ports in northeast China as my troops moved south. I had also hoped that with more units I could end the war in China quick, and pivot to preparing for the Allies sooner. Would that have been the best strategy had I played through the years longer? Maybe not. But all these ideas will be very helpful on my next play-through.
 
Taking Natchi is actually not much slower than in HoI2. I annexed Natchi May 1937 with barely only a single LArm brigade built, and forgetting a Corps at the Manchu-Soviet border. Make a landing at the two CHI ports, your garrisons are actually pretty useful using strat redeployment.

That's 10 IC finished Oct 1937 to kick it off - and you can also run a few serials besides to keep some expertise (BBs or cruisers or interceptors).
After taking CHI+CGX+CSX+CXB+CHC you will have 40-ish leadership.
 
Sadly Nat. China is getting too easy to fully conquer, they need more militia(10-15) starting at the GuangXi boarder and 5 of the commies divs, also Nat. China should be able to enter Sianxi(sp?) when war breaks out.
 
Great tutorial. I'm going to have to retry Japan again after my Soviet game.
 
I disagree with the use of tanks. Useless in that terrain, expensive to produce and develope. I prefer the use if militia, rarely additional infantrys. Militias do a good joob at keeping up a frontline and for the best reason, they require a third of the officers a infantry needs. Spares Leadership.

And in second i disagree with the tactics to conquer USA by 38 for i like to play somewhat historically. IMO takin US in 38 or 39 is an exploit of the game, for AI is not able to defend against and invasion and in a special way in 38.

And besides: wheres the fun if you got US in 39? There will be no real opponent, for the UK will be seriously ass kicked by german AI.
