[Template:Anthology](/wiki/index.php?title=Template:Anthology&action=edit&redlink=1 "Template:Anthology (page does not exist)"){.new}
[Japan]{.mw-selflink .selflink} must expand to thrive. Japan has thesecond weakest industrial base of all Major powers (better only than
Italy), and limited resources. Japan is one of the most challenging, and
also the most fun, major power to play because it requires a mastery of
land and naval warfare. The need for expansion is not optional, as Japan
will drive deep into the mountains of China to the jungles of Indonesia,
and if successful far beyond.
- Industrial: Japan\'s highest priority are techs that boost IC, IC
efficiency, production time and research efficiency. Generally, oil
conversion techs are also important due to Japans lack of this
resource. Try to always be a step ahead with decryption and
encryption techs, as these will help you win naval battles. Manpower
techs might be good, but if you choose to rely on puppets to supply
the bulk of your infantry, these techs can be safely ignored until
later in the war.
- Infantry: Good infantry and marines are essential, while cavalry and
mountaineers are good but not necessary. Japan do begin with quite a
few cavalry divisions, and it might be worthwhile keeping them up to
date.
- Air force: Fighters and tactical and naval bombers are most
important due to the great ranges necessary in Asia and the Pacific,
but you can also build airfields near expected fronts and research
interceptors and CAS.
- Navy: Aircraft Carriers and up-to-date support ships are a must,
with Admiral Isoroku Yamamoto Japan can easily rival the US in
leading the world in Naval Doctrine techs.
See a complete listing of all [Japanese Tech
Teams](/wiki/Japanese_Tech_Team "Japanese Tech Team"){.mw-redirect} .
Japan begins the game with a puppet state Manchukuo, which is also its
first ally. During the invasion of China, Japan will be prompted to
create Mengukuko as a new puppet, which is always a good choice. Later
in the game, Japan must decide whether or not to join the Axis. Joining
the Axis too early is dangerous, as it will embroil Japan in a war
against the Allies, and later, the Soviet Union. For these reasons,
Japan does not typically join the Axis.
Japan receives several free slider moves. Assuming a historical
direction, Japan will have 6 hawk moves and 6 interventionism moves by
1939. Since only 2 of each are needed in 1936, both can be safely
ignored. Therefore, early slider moves are best towards Central
Planning, which will provide immediate IC bonuses. With Central Planning
maxxed by 1937, in 1938 slider moves should drive towards Standing Army.
Japan begins the game with decent ministers, but fortunately a good pool
of alternatives. If Japan will listen to the demands after the 2-2-6
incident, no initial minister changes are worthwhile.
- **Chief of the Army:** Satoru provides a -15% supply consumption
bonus
- **Head of Intelligence:** Shiro provides a +5% IC bonus
- **Armaments Minister:** Gotaro provides a +5% IC bonus, and +10%
industrial research bonus
Before the Sino-Japanese war begins in the summer of 1937, minister
changes are essentially \"free\" due to the reduction of dissent the war
causes. Changes can include:
- **Armaments Minister:** Kazue provides +20% supplies
- **Chief of the Army:** Satoru provides a -15% supply consumption
bonus
- **Chef of the Navy:** Jisaburo provides a minor carrier defensive
bonus
- **Chief of Staff:** Tashiro provides a +20% org regain
- **Minister of Security:** Keisuke provides +15% foreign IC use,
while Kesago provides manpower bonuses.
Japan will benefit from spying, particularly in stealing blueprints from
the USA.
Japan has several resource shortages at the beginning of the game,
including a deficit of rare materials and metal. In fact, without having
Manchukuo as a puppet, Japan would have extreme resource shortages,
which accurately reflects Japan\'s enormous reliance on foreign holdings
to support its nascent industry. Japan\'s best trading partners are, in
order:
- USA: Japan\'s best trade partner before war. Trading the USA for
money is a great way to free-up IC used on consumer goods.
- Siam: Favorable trades, but not much to trade.
- Germany
- Italy
- Turkey
- Soviet Union
- France
Early industrial production for Japan is not wise nor necessary, due to
the early war with China. Japan needs to perform all upgrades to ensure
all infantry are 1936. Airbase production can be helpful for islands,
since airbases lift the fog of war for the adjacent sea province.
For Japan\'s existing military, some players prefer to remove island
based garrisons in order to use them to quell dissent in occupied China.
The Japanese military begins the game very heavily brigaded, with a huge
amount of anti-aircraft brigades, and some anti-tank brigades. AA
brigades will only slowdown mainland China infantry, but can provide
some benefit to island garrisons. For military production, Japan will
rely heavily almost exclusively on Infantry without brigades and HQ
units. Some players may also build Marines, Cavalry and Mountaineers for
rapid movement in some terrain types. Militia can help bulk out Japan\'s
armies in China, and are very affordable as Japan has lots of manpower
to burn but not the best IC. Generally, Japan does not have the TC nor
the fuel necessary for a serious motorized army until later in the game.
After a summer of upgrades, Japan can build a nine-parallel run of
infantry, creating around 45 infantry divisions before the war with
China.
Mastery of the seas is vital for Japanese success. As such, the [Naval
Primer](/wiki/Naval_Primer "Naval Primer") is required reading for a
Japanese player, with particular focus on [Carrier Task
Force](/wiki/Carrier_Task_Force "Carrier Task Force") . All ships are
useful, but carriers, light carriers, destroyers and submarines
especially so.
The Japanese starting fleet is arguably the most powerful in the world,
with the UK\'s Royal Navy being a close second. When the starting fleet
is properly re-organized into a CTF and SAGs, the Japanese Navy is a
formidable force. The main limitation of the older naval models is
limited range, but these are still very useful for local defensive
missions, particularly sub hunting. The entire starting fleet \-- 97
vessels in total \-- require 6.3 IC dedicated to supplies. A simple
reorganization will create two SAG fleets (30 vessels each); two
transport fleets (10 vessels each); a sub fleet (6 vessels); and a CTF
fleet (3 carriers). The CTF, with a 3000 km range, is best accompanied
by modern destroyers.
Despite its early dominance, Japan will need to dedicate considerable
time and effort to its Navy, with a strong focus on carriers. No less
than two parallel carrier builds should begin no later than 1938. Extra
transports and convoy vessels are also particularly helpful.
The vast distances and varied terrain over which Japan can expect combat
make air power a good investment. The mountains and low infrastructure
of China translate into long, ORG-sapping marches for your infantry,
which means that anything you can do to ORG losses in combat is
important. Bombers can keep Nationalist forces at low ORG, making for
easy victories and a faster conquest of China. In the Pacific, the huge
distances between island fortresses and both sides\' dependence upon sea
transport and supply means that careful use of aircraft give you freedom
of movement and deny it to your enemies. However, Japan\'s relatively
low IC means that fewer aircraft can be built and maintained. This
forces Japan to concentrate on fewer types of aircraft than its primary
opponent, the United States.
Japan starts with TAC, INT, and NAV. INT are less useful in the Pacific,
due to their shorter range, but can still perform well, especially if
you focus on Asia and Africa or even Europe rather than the US. As for
bombers, Japan need only focus on TAC and NAV, though CAS can be great.
STR are pointless in Asia, since IC is spread thin, and would only be
useful against the USA after capturing Hawaii. Their high IC cost means
that they will provide very little bang for their buck. TAC and NAV
should be your highest aircraft priority. They benefit from the same
doctrines and TAC is versatile enough to reduce ORG of land units and
inflict some damage on ships. NAV is really a no-brainer for Japan.
Due to Japan\'s lack of IC, you might be tempted to skimp on ESC for
your TAC and NAV. Don\'t. A couple of bad rounds of combat can end up
costing more IC and time than it would have taken to build them in the
first place.
This event occurs on February 25, 1936:
- Crush this coup: Gain 1 dissent, 1 move to interventionism, 3 to
democratic, 4 to political left, and 1 to closed society. Remain
Paternal Autocrat.
- Listen to their demands: Gain 3 dissent, 2 moves to interventionism,
3 to authoritarian, 3 to political right, 3 to closed society, 1 to
hawk lobby. Become a National Socialist nation. Minister changes
include Shiro to Head of Intelligence, and the loss of Social
Conservative ministers such as Gataro.
For a normal game, listening to demands is a far more powerful choice,
though as the game progresses a subsequent series of coups will cause
Japan to alternate between Fascist and Paternal Autocrat regardless of
the choice made here.
Beginning in January, 1937, Germany will likely seek agreement in the
anti-comintern pact. If it does, Japan has the following options:
- Sign the Pact: move 1 authoritarian, 1 interventionism.
- move 1 isolationism
This event is among the most important events for Japan, as it signals
the beginning of the Sino-Japanese war. The event may fire anytime
between June 1, 1937 and August 29, 1937.
- Teach the Chinese a Lesson: War with China. Loose 10 dissent, gain 1
interventionism, 2 moves to hawk, 50 new manpower.
- We Cannot Afford a War: Gain 3 dissent, move 1 to dove lobby, and 1
to isolationism.
After the Nanjing Massacre, the Japanese attack US vessels:
- Compensation must be paid: Loose \$500, and 1 move to isolationism
- Let them know fear: move 1 toward interventionism, loose 1 dissent,
gain 1% belligerence.
This event will occur sometime in 1940:
- These documents are important: Gain 1 interventionism, 1 hawk, and
1000 oil
- These documents are irrelevant: Move 1 isolationism, 1 dove lobby
After a Japanese victory against China, Japan has three options:
- **Install a loyal puppet:** All existing Chinese warlords will be
annexed. Nationalist China will be recreated in part, with Japanese
holdings surrounding it. This is a powerful choice, and many players
see this as the most gamey choice: Nationalist China will provide
Japan an enormous number of free infantry.
- **Carve up the Chinese lands:** Japan will recreate four Chinese
warlords as puppets, while Nationalist China will disappear. Each
puppet is larger than they were in 1936, but still relatively weak.
This is often considered the most historical option, since Japan did
historically create two puppet enclaves. This option also prevents
any one puppet from being ridiculously strong, while still being
strong enough to provide Japan with some assistance.
- **Total occupation:** Japan will automatically annex all
adversaries, with the exception of Sinkiang, and gain 3 dissent.
Japan gains a total of 34 base IC with this option. In HoI2 and
Doomsday, the partisan activity in such a massive land mass will
seriously hurt Japan, and cripple Japanese
[TC](/wiki/TC "TC"){.mw-redirect} . In Armageddon, partisan activity will disappear within 2 years, well in time for the war with the
Allies.
There is a way you can choose both of the first two options. Click
\"Carve up the Chinese mainlands\" when you get the event, then go to
the diplomacy tab where you can create Nationalist China as a puppet.
Interestingly, even though it\'s a puppet, Nationalist China will still
annex the warlords if the latter lose enough provinces in a subsequent
war. You can also use the diplomacy tab to create puppets if you chose
\"total occupation\". Be sure to create Yunnan and Guanxi clique before
you create Nationalist China. You won\'t be able to create Shanxi this
way if you earlier created Northern China.
This will occur between July 15, 1938 and September 20, 1938. The player
does not have a choice about the effects, which are: loose 3 manpower,
loose 500 supplies, move 1 hawk.
Beginning January, 1939, Germany will likely seek agreement in the
Tri-Partiate Pact. This is a meaningless agreement in game terms. If
Germany offers the pact, Japan has the following options:
- Sign the Pact: Gain 10 money, 1 move to interventionism
- This Pact is not Needed: Loose 10 money, move 1 isolationism.
This will occur between May 11, 1939 and September 20, 1939.
- We have lost this battle: Gain 1 dissent, loose 40 manpower, loose
1500 supplies, 1 step hawk.
- This defeat must be avenged: War with the Soviet Union. Gain 1
dissent, loose 40 manpower, loose 1500 supplies, 2 steps hawk.
After Germany defeats France and creates Vichy, this event will fire
(usually around June 26, 1941).
- Demand Indochina: Inherit all of Indochina, receive four garrison
divisions.
- Demand Airbases: Gain 3 militia divisions, and two territories in
Indochina.
- Demand Indochina and Madagascar: It is very likely Vichy will refuse
this request. Otherwise, Japan will gain all of Indochina and
Madagascar.
As soon as the war against the USA starts you can choose to carry out
the Surprise attack against Pearl Harbor or not.
If you do so you get
- Ambush Chance +30%
- Air and naval surprise chance +40%
- Land surprise chance + 20%
- one move towards hawk lobby
From now on there is a 10% chance every two months that the enemy
recovers.
If Japan carries out the surprise attack the USA get
- -1 dissent
- +3 hawk lobby
- +4 interventionism
- +250 manpower
- +50 relations with UK
So the benefit for Japan is relatively small, the benefit for the USA is
huge. So consider carefully which option you choose, only a very fast
moving and very aggressive Japan will find that the bonus may outweigh
the bonus for the USA. It is, however, gamey to \"cancel the operation\"
when at war with the USA.
After the war with the Allies begins, this event will occur:
- Lean on Siam: Siam joins the Japanese Alliance
- Siam is Unimportant: No effect.
In Armageddon this event fires as soon as Japan and Siam are in the same
alliance, no matter how that happened:
- Siam becomes puppet state of Japan
Japan\'s militaristic expansion is the most complicated to manage of any
other nation in the game. The war with China is fairly structured in
terms of game events, and will proceed relatively easily. After a
Japanese victory against China, however, Japan will not have any other
events that lead into war until Pearl Harbor at the end of 1941.
China has large tracts of land with low infrastructure and difficult
terrain, so victory will not be swift: defeating China in one year is a
good goal. All available forces can be dedicated to the war effort since
Japan has complete naval supremacy over its neighbors: no invasion of
the home islands, for example, is possible. Japan begins the game with
three HQ units which is a reasonable amount to have for a successful
Chinese campaign.
Japan\'s strategy during the war is to drive to complete annexation, and
this can be achieved generally through force overruns, since the
Japanese infantry and land doctrines are more advanced. Additionally,
Japan can benefit from amphibious landings to split the Chinese force.
Note that attacking the warlords (with the obvious exception of Shanxi)
is not necessary and best avoided, since after the defeat of Japan they
will capitulate. Otherwise, attacking a warlord means their nation and
army will be annexed by Nationalist China after they\'ve lost a few
provinces. Communist China is not a typical warlord, and does not always
join the war against Japan, but if it has it will be a thorn in Japan\'s
side. The Communists have very defensible terrain due to land forts,
mountainous terrain, and rivers. A containment strategy is effective \--
dealing with them only after Nationalist China has been defeated.
During your advance (and later, occupation) partisans will prove to be a
very annoying menace. This is especially true in HoI2 and Doomsday, but
not in Armageddon. Partisans reduce your transport capacity and will
likely spark random province revolts. Since Japan starts the game with
31 garrisons, a good portion of these can be redeployed to reduce the
partisan rating of occupied provinces. Each garrison exerts influence
not only in the province where it is stationed, but in adjacent
provinces as well. Therefore it\'s not necessary to have a garrison in
each province, and many players use a checker board pattern.
Mountaineers are the best weapon in dealing with revolts, since the vast
majority of China is mountainous.
In ARMA there are two puppets you can create DURING THE WAR. Northern
China and China-Nanking. If you created Northern China during the war
and then choose \"Carve up the Chinese Mainland\" in \"The Fate of
China\" Shanxi will only consist of Anyang, and in some instances
Changde.
Historically Japan had several skirmishes with the Soviets which
eventually led to Japan attempting to increase its borders by a few
kilometers into Mongolia. The game models these essentially tactical
level battles via events in 1938 and 1939. The Nomonhan Incident event
will allow the player to declare war on the USSR. If Japan attempts to
take on the Soviet Union in 1939, it will be an uphill battle. Japan
will at best acheive a stalemate or some few gains in Siberia until the
Germans attack; when they do, Soviet is likely doomed.
Some players suggest attacking the USSR immediately after Germany\'s
Barbarrossa. This would allow Japan a fairly easy battle against the
Soviet Union, especially by attacking through Sinkiang. This soft
underbelly of the USSR will have vast amounts of resources and industry
in a relatively short distance. Due to this extreme Soviet weaknesses,
most players view this as a gamey strategy. You can also get around a
non-aggression treaty by declaring war on one of that country\'s allies.
You can get around the Non-Aggression treaty from Nomahan by declaring
war on Mongolia or Tannu Tuva. You\'ll get a notice saying the Soviet
Union has broken the non-aggression pact.
Planning the war against the Allies is incredibly complex, far more than
the planning required for any other nation. Specifically, Japan must
develop distinct plans for:
- Far West: formerly the border of Sinkiang, now Japan borders British
India and Pakistan. This presents the fastest opportunity to take
India.
- South East Asia: Japanese border with British Burma. This is a
difficult border and movement will be slow.
- Hong Kong: British stronghold
- Malaysia: Enormous source of British rare materials, with almost no
defenses.
- Indonesia: Annex the Netherlands government in exile after taking
just 7 VP territories, usually without any defenses.
- Philippines: A US puppet close to the homeland.
- Australia: A friendly harbor for US and British forces
- Pacific Islands: Guam, Wake Island, Midway, Johnson Island & Hawaii
A veteran HoI2 player can achieve all these objectives as Japan in less
than 6 months. In fact, the key to such sweeping success is extremely
rapid movement, as giving the enemy time to recover, especially the USA,
will lead to disastrous results. Historically, Japan understood that
while Malaysia and Indonesia were its main targets, the USA would
ultimately interfere with its expansionism. For this reason, Japan\'s
first most important target are the US Pacific Islands followed by the
Philippines.
At least one major naval battle will occur, likely early in the war. The
British fleet is no concern, but the US Navy will have a fairly powerful
fleet. It is very important to engage relatively early (before the USA
begins massive carrier building programs), and ensure enough carriers
are in the battle. Typically, an eight carrier engagement (two 12 CTF
fleets, for example) with 1941 CAG upgrades are sufficient. With
advanced naval doctrines and upgraded CAGs, the US Navy will suffer a
devastating blow. So long as at least one US carrier remains in the
battle, Japanese carriers will continue sinking US ships beyond firing
range.
Pacific Islands, Malaysia, the Philippines, Indonesia, Burma and India
all cause zero dissent when captured. This makes it possible for
Japanese TC to remain green despite tremendous expansion of the empire.
Australia, however, has very high dissent when territories are taken,
and garrisons are essential for quelling future revolts. Due to the
horrible landscape and infrastructure, try to capture provinces using
troops from transports. Even after troops make landfall, instead of
moving them on the ground, load them back onto transports to take the
next territory. It is not necessary to take every province when
attacking the Netherlands, Philippines, and Australia: focus on the VP
provinces for annexation.
After a complete conquest of the Pacific Theater, what will Japan do?
Japan has three distinct options:
- Defense: Defend all pacific islands captured, continue fleet
building, and see how long you can last against the US Navy. This is
the most realistic option.
- Soviet War: Considering the Pacific War can be won by the summer of
1942, the German offensive against the Soviet Union has likely begun
to stall. This option is fairly realistic considering past tension
with the USSR. The Soviet far east, in particular, had long been
sought after by Japan, and the nation of Primorsk can be released.
- USA mainland: This can be challenging, but also surprisingly easy.
The invasion route is simply: San Diego \--\> Panama \--\> New York.
Focus all efforts on the North Eastern USA, as that will hurt the US
the most.
An effective defense relies on a good offense. Japan can take all
islands in the Pacific and garrison them. Some islands, such as the
Aleutian Islands in the North and Christmas Island in the South, can be
a good place to build naval bases. A naval base on Christmas island can
later be used to capture Panama, and make US naval travel a little more
difficult. Airbases are also very useful, since they lift the fog of war
for adjacent sea provinces, so massive airbase building and deployment
to islands is helpful. Moreover, airbases provide a staging ground for
naval bombers.
A good attack on the USSR needs a lot of cavalry or motorized infantry
to quickly grab VP provinces before they can respond.
Considerable abuse of the AI and game system (e.g. \"gamey tactics\")
are possible. Almost all [gamey
tactics](/wiki/Gamey_tactics "Gamey tactics") are completely ahistorical
and unrealistic, and many players consider them cheating. For example, a
puppet Nationalist China is extremely powerful, producing hordes of
infantry. Even Communist China can be made into a puppet through a peace
deal, giving Japan access to excellent commanders and a relatively
advanced army of infantry and mountaineers.
The year is 1936, we\'re in August and Persia is the key toward the
world. Declaring war will be easy because most nations ignore the
Persians. Landing in Persia is easy because they don\'t idolize a navy
and can\'t stand up toward your mighty armada of death. you will need
about 5 infantry units and 7 militias. once conquering Persia you will
have entries into the middle east, Soviet union, Afghanistan, and India.
Build up all troops into Persia and create garrison borders around you
colony.
After Persian Victory, you are at war at china. play correctly and you
will win by 1938. This gives you 3 years until the next major war.
During this period, Japan is having a peaceful year. We can change this.
Quickly declare war on Belgium and land in there colonies. They never
bother to defend them. After your conquest of colonies, build up units
and hit the main land. Taking Belgium will give you a french entry
point. More importantly, Ireland.
With your colonies, you are in the early 1939 period. Declare war on
Ireland because they are weakly defended. land in the ireland with 2
Tanks and 1 infantry. Push them away from Dublin and move them west.
soon Ireland is beaten and you have a great colonized empire.
Now you can attack France from Brest, North east France and all of
western Africa. Once you conquer France, you should offer an Axis
alliance so you can create the massive mega power.
In some circumstances Japan can form an alliance with
[Sinkiang](/wiki/index.php?title=Sinkiang&action=edit&redlink=1 "Sinkiang (page does not exist)"){.new}. If Japan declares war on the Soviet Union while it\'s allied with
Sinkiang\--and it\'s not yet at war with [Nationalist
China](/wiki/Nationalist_China "Nationalist China") and [Communist
China](/wiki/Communist_China "Communist China") \--the others will often
side with Japan and Sinkiang because of an event they receive. If
Nationalist China went Fascist at the Xian Incident, it will revert to
Paternal Autocrat when it joins this United Front. Sinkiang will often
formally change its alliance from Japan to China, which means it\'s
likely to get annexed during the war, as is [Xibei San
Ma](/wiki/Xibei_San_Ma "Xibei San Ma") .
