This mod requires Brave New World.



The Republic of Ezo (Ezo Kyōwakoku) was an unrecognized state that existed briefly in northern Japan in 1869, at the end of the Boshin War between the Tokugawa Shogunate and the Imperial Court. With the end of Japan's feudal order fast approaching, remnants of the Shogunate forces fled to the island of Ezo, known today as Hokkaido. There, in the city of Hakodate, the samurai proclaimed themselves an independent republic with a governmental structure based on that of the United States. The aim of the Republic was to develop the island in the name of the Emperor to defend against any potential Russian attack, as well as to continue the traditions of the samurai class.

Enomoto Takeaki[]

Samurai, admiral and President of the Republic, Enomoto Takeaki was admired and respected on both sides during the Boshin War. Born into loyalty to the Tokugawa Shogunate, Enomoto spent his early life procuring Western technologies for use by his feudal lord. He became fluent in English and Dutch, and secured several advancements such as the telegraph on his visit to the Netherlands. Enomoto was a commander in the Tokugawa Navy when war broke out against the Satchō Alliance, the forces attempting to restore power to the Emperor. Upon the surrender of Edo (Tokyo) in 1868, he escaped with his fleet to Ezo to declare an independent republic. The remaining Tokugawa loyalists elected Enomoto as President, in the first election in Japan's history. After the collapse of the Republic, Enomoto continued to be held in high esteem by the Meiji Government and later became a founder of the Imperial Japanese Navy.

Dawn of Man[]

The democratic world salutes you, President Enomoto Takeaki, respected Admiral of the Japanese Navy. You lead the determined people of the Republic of Ezo, Japan's first elective state in its far northern reaches. In the twilight of war, you brought your followers and advisors to the island of Ezo to establish a new portion of the Empire and to continue the traditions of the Samurai class. You reached out to the powerful nations of the West, learning their languages, their systems and their technology for the betterment of your home. Although your Republic was short lived, it left a legacy of democratic rule that eventually found its way to the whole of Japan.

Ezo Icon

The Republic of Ezo is a maritime civ focused on diplomacy and defense, which will help you secure your coastal territory while pursuing the victory type of your choice. Defensive bonuses are apparent from turn 1 - Ezo's Unique Ability, Goryokaku, automatically constructs a Citadel on a nearby tile as soon as the Capital is founded. The Citadel will be placed on a tile with a low Food yield and will avoid Bonus or Luxury resources, so don't worry about positioning and settle wherever you like. As a coastal civilization, this Citadel will secure your Capital from land-based Barbarian invasions while you use the opening turns to build up infrastructure and get started on a navy.

After meeting a few rival civilizations, seek out potential friends as soon as you can. Upon signing a Declaration of Friendship, Ezo will receive a copy of their friend's strongest researched naval unit at the start of their next turn. This includes any possible unique units, as well as the standard Ironclad (which Ezo usually cannot build). These units will be received at level 2, ready to be promoted, making them an excellent way to bolster an early-game naval force.

As mentioned, Ezo's Unique Unit is a replacement for the Ironclad. The Jokisen is a steam-and-sail frigate that, while less powerful than the base Ironclad, is much cheaper and spammable thanks to its lack of a Coal resource requirement. Unlike the Ironclad it is not slowed down outside of Coast tiles, meaning it is able to join your Privateers out on the open ocean. Furthermore, it begins promoted with the Boarding Party I and Supply promotions, for an extra combat boost and the ability to heal outside of your borders.

Ezo's final unique component is the Bugyosho, a replacement building for the Armory. The Bugyosho is a useful tool for supporting the development of your mid-game settles, as any Worker within three tiles of the city will construct their improvements twice as quickly. Be careful, however, as the Bugyosho still requires that a Barracks be present in the city before it can be constructed.

Upon researching Steam Power, any city with a Bugyosho will be able to train the Foreign Legion while Ezo has at least one active Declaration of Friendship. Not only is this normally-rare unit equivalent to a Great War Infantry available at a considerable production discount, but it can be trained a whole tech earlier than its standard counterpart. Be sure to maintain your friendships going into the Industrial Era so you can take advantage of this early firepower on land.
