The people of Ezochi are a thorn in our side, operating as a base for brigands who come south to hound our peaceful subjects. We must extend our benevolent rule north to this wild land, and ensure that the people there learn the benefits of our ways.
The following provinces are owned by our country or its non-tributary subjects and follow our religion:
All owned provinces in Hokkaido area get "Subjugating the Ainu" for 20 years, giving the following effects:
-2 Local unrest
+10% Local tax modifier
Our country gains permanent claim on The Kurils (1032) and the Sakhalin area
Take the Kurils
The Son of Heaven requests that the islands to the north of Japan be settled with landless Ronin for the peace of the Emperor.
Our involvement in Manchuria and among the Thousand Islands requires a new defensive frontier. The taigas of Siberia may not be the most alluring of lands, but they will provide a good first line of defense against anyone from the west who wishes to attack our more prosperous territories.
All provinces in the following areas are owned by our country or its non-tributary subjects:
Every owned province in the East Siberia Region gets "Siberian Boom" for 10 years, giving the following effect:
Many years have passed since the Divine Wind blew an invading Mongol army away from Japan, and saved the Motherland from foreign invasion. In the future, perhaps we should be better prepared?
Has a navy of at least 90% of its Force Limit
Has at least 5 heavy ships
Gains 20 Navy Tradition
Gets "Divine Wind" for 20 years, giving the following effects:
+0.25 Yearly Navy Tradition
+10.0% Recover Navy Morale Speed
The upstart rulers of Korea claim that due to their mandate from Heaven that they are in fact superior to the Japanese Emperor. We must launch an invasion and take the southern portion so we will be able to punish such arrogance in the future.
As our reach grows, so too does our need for defense. While we look to the west for opportunities to grow, we must also take heed of the great expanse to our east, the Pacific Ocean. Who knows what threats may come from that direction? It would be prudent to assert our power among islands of the Pacific, lest some other country claim them and strike us from the east.
Beyond the sea lies a New World, full of opportunity. Some even whisper of a kingdom wealthy beyond measure, a golden state ripe for the picking. We should establish bases in those lands and profit how we can from what is discovered.
The ways of our warriors must be guided at all times by a sound philosophy of virtue and proper conduct. Loyalty, honor and obedience, such is the way of the Bushido. Strengthen our military tradition, and our realm will be respected throughout Japan.
Our country has at least 40 Army Tradition
Our country gets "Strengthened Bushido" for 20 years, giving the following effect:
Any remaining Daimyos who have not yet submitted to our authority must be brought to heel immediately. Only under a united Japan can we hope to expand beyond the home islands.
Although our domestic opponents have been subdued, it is important that we keep these lords in check. Building a new system of roads and waystations would help make the daimyos' domains easier to reach from the capital and boost local commerce along those routes in the process.
Our country owns at least 15 provinces with either:
A great temple
A counting house
Every owned province in the country gets "Gokaido Stations" for 20 years, giving the following effects:
+10% Friendly Movement Speed
-0.05 Monthly Autonomy Change
Rather than simply imprison the worst lords and risk rebellion, we can take a far more subtle approach to weakening and integrating them by obligating them to visit the capital regularly. Implementing a policy of 'alternate attendance' would compel the lords to maintain two residencies, one in their own domains and one in the capital, and of course they would be expected to travel back and forth in extravagant processions. The cost of all this would bankrupt all but the wealthiest lords, preventing them from accumulating the funds they would need to maintain a private army. It would also help bolster our own power in the capital, and make it a far more attractive place for courtiers and diplomats.
Has +3 Stability
Has at least 80 Legitimacy (or equivalent)
Our country gets "Sankin-Kotai" until the end of the game, giving the following effect:
+1 Diplomatic Relation
Construct the Gokaido
Regulate the Social Order
To prevent another age of chaos, we must make sure that everyone knows their place in society. Samurai must remain samurai, merchants must remain merchants, peasants must remain peasants, and nobody gets any funny ideas to the contrary.
Society is divided into four parts, which need to be in perfect balance to create a truly harmonious society. This period of ours is sadly one of gekokujo, where even the lowest can overcome the highest in society. We must find a way to remedy this grievous ill and restore harmony.
Two estates have at least 60 loyalty
If our country has a Stability of less than +3,
then it gains +1 Stability
else it gains 100 Administrative Power
Issue New Erizeni-Rei
Sound finances are the bedrock of stable government. To ensure that order is maintained and trade continues, we must encourage a steady flow of good coins into the realm.
Our country has an Income of at least twice its starting income
Our country gets "Currency Regulations" for 20 years, giving the following effects:
+5% National Tax Modifier
+0.10 Yearly Inflation Reduction
Balance the Four Divisions
Many daimyos have suffered from erratic finances, causing some to default on loans they have taken. Enabling smaller money change shops to offer more reliable loans, and to back up those loans with our own reserves, should help stabilize daimyos' finances and perhaps foster a healthier domestic economy.
Our country has at least 2 000 Ducats
Our country gets "Growing Economy" for 25 years, giving the following effects:
-10% Construction Cost
-25% Construction Time
Issue New Erizeni-Rei
Survey the Secret Fields
It is embarrassingly common in the provinces for farmers to maintain so-called 'secret fields', farmland hidden from the eyes of tax collectors. A thorough accounting of these unreported properties should significantly help bolster the health of our economy and our coffers.
Our country has less than 0.1% Corruption
Our country gets "Cadastral Surveys" for 20 years, giving the following effect:
+10% Production Efficiency
Construct the Gokaido
Encourage Wealth Cliques
As our economy continues to grow, the merchant classes have inevitably grown in wealth and power. Although officially they are at the bottom of the social ladder, it's hard to look down on people so rich and so financially adept. Perhaps it is time we actively supported these merchants, and helped them develop these... what should we call these mercantile conglomerates? 'Zaibatsu'?
Our country owns at least 12 provinces with any manufactory
Gains 100 Administrative Power
in its capital province
Gains 5 Mercantilism
If owns core province Chikuzen (1818):
Chikuzen (1818) gains 3 Base Production
our capital gains 3 Base Production
Survey the Secret Fields
Dominate the Markets
Our economic output is astonishing and our prestige is second to none, yet our people overseas still don't get the respect which they rightfully deserve.
Our country has 85% or more Trade Power in Nippon trade node
One of the following must be true:
Our country has 75% or more Trade Power in Beijing trade node
Our country has 75% or more Trade Power in Canton trade node
Our country has 75% or more Trade Power in Hangzhou trade node
Our country gets "Trade Hegemon" until the end of the game, giving the following effect:
↑Theoretically these missions would also be available when starting as Japan and the leftmost column would also be available when starting as an Independent Daimyo, but there is no start date where Japan or an independent Daimyo exist. And there is no way to get these missions without starting with them, because forming Japan doesn't give new missions.
