Kon’nichiwa! Hello and welcome to a long time no see, Millennium Dawn Dev Diary. I (TheGeneral) will guide you through some of the ideas of the new Japanese content for the upcoming DLC. One of the key parts of the rework of Japan is the design of Article 9. For those who don’t know, Article 9 is an article in the constitution of Japan where the military is only allowed to act on self‑defense. This has been part of the Japanese constitution since the end of World War II. Article 9 is still active until this day, but it has had new interpretations. This would ease the use of the Japanese military.

Keep in mind that all of this is still a work in progress, and things are subject to change including but not limited to parties, graphics, etc.

Starting Situation

We want to reflect that in the new Japanese content, but also give the player a way to remove it faster than real life. To do this we have designed a Balance of Power (BoP) for Article 9.

Balance of Power for Article 9

On the left you have strict pacifism (the start value) and on the right the highest interpretation level. We have hijacked the BoP to act more like a progress meter; your goal should be to push the bar as far right as possible. Why, you wonder? Well, this is your starting modifier:

As you can see, you really don’t want that! On the plus side you get a high stability modifier and your units will be very good at defending and attacking on core territory (reflecting self‑defense).

As Japan, you will have ways to increase your interpretation level but other countries might impact it as well.

Decisions that can affect the BoP

These decisions are available to you as Japan, where you have the power as the player to activate them. Three of the choices are locked behind world tension; the other two depend on your domestic political situation:

Liberal governmentConservative government
Decision unlocked by liberal governmentDecision unlocked by conservative government

The most other decisions you have in power is the aggression of China. If China is increasing its Chinese Agression, you will unlock more decisions to raise your interpretation level.

Also the choices North-Korea and Russia are making, will give you ways to change the BoP:

Decisions from NK and Russia

In the political tree we also will have focusses which will help you, in combating Article 9. Maybe even your USA friend can help (Donald Trump WILL push this button):

Now don’t worry. As Japan you still are able to work on your army. With Article 9. You have access to these focusses:

These will help improve your equipment and defense capabilities mostly. Your goal is to get to the ‘Establish the Defense Transition Committee” as fast as possible. This will help you get rid of the BoP:

Defense Transition Committee focus

These will unlock missions which autocompletes to improve your article 9. This reflects that a constitution change just can’t be done in 70 days and your whole military is ready to fight in the world.

Once the negative penalties are gone. Its time for Japan to abandon Article 9 and become a new military power in Asia

When you complete the Formalize National Defense Capabilities, you unlock the full potential of the Japanese Military Focus Tree. To compensate for your struggle, the bonuses you gain will be a bit stronger then you would expect normally..

Post‑Article 9 bonuses

When you have completed the Japanese Military Branch. You have a very solid military at your disposale and even Japan gets into space (sorry Poland). Remember your Article 9 modifier? Well at the end it becomes like this:

Final Article 9 modifier

As you can see. Those rewards are powerful. Also via decisions and space focusses you unlock other bonuses which will help taking back the tide and not being a sitting duck.

And with that, that’s all for now. I have shared our plan to the Military of Japan, but now it’s your turn to tell us what you think, and we’re looking forward to hearing your feedback. Matane!
