Situation

Nanbokuchō Jidai

nanbokuchou

Following the dismantling of the Kamakura Shogunate, Imperial rule was reinstated under Takaharu with the help of Takauji in what is known as the Kenmu Restoration. However, the two former allies quickly became bitter rivals. Takaharu wanted to restore the supremacy of the Imperial rule like it was in the Heian Period, which earned him/her the discontent of many in the warrior class, including Takauji. The latter was pushed out from the capital and forced to flee to Kyūshū, but was able to return to Kyōto in 1336 and seize it, establishing a new Japanese Shogunate under him/her and enthroning a new Emperor. In January 1337, Takaharu fled the capital and established his/her own court at Yoshino, starting the period known as Nanbokuchō Jidai, the Northern and Southern Courts.

The game's hint

The Nanbokuchō Jidai is a Situation that divides Japan into competing Imperial Courts, the Northern and Southern lines, each seeking legitimacy. Clans must choose sides, as this conflict will reshape the entire island nation.

Recommended Actions:
Use the unique Nanbokuchō Jidai Casus Belli to wage war for your chosen Imperial claimant.
You can force the rival court to abdicate by using the Force Imperial Abdication Peace Treaty and secure supremacy for your preferred Emperor.
Use the Raid Clan Holdings and Raid Imperial Family Holdings Unit Abilities to gain Warscore
Expand your Clan influence with Expand Clan Influence to seize enemy Locations.

Extra Hints:
Careful timing is crucial. Smaller Clans can use the conflict to gain leverage over rivals.
Consider the balance of power before committing to a side.

Situation Outcomes 4

The Imperial Line Is Broken

No court consolidates the throne: the capital stays where it is, the sacred regalia are not gathered, and the imperial succession simply lapses.

Requirements

The Imperial Line Reunites

One court annexes the other under their shared ruler, forming a reunified Yamato, moving its capital to Kyōto and installing the three sacred regalia there.

Requirements

Jimyōin Prevail

Jimyōin move their capital to Kyōto, install the three sacred regalia there, and build or upgrade their Gosho, gaining a lasting boost to Government Power and Prestige if they hold the emperorship or the shogunate.

Requirements

Daikakuji Prevail

Daikakuji move their capital to Kyōto, install the three sacred regalia there, and build or upgrade their Gosho, gaining a lasting boost to Government Power and Prestige if they hold the emperorship or the shogunate.
