Jiyuu System

The Jiyuu System has been a center of activity in the SARPiverse. Many stories of great intensity have been forged here, and have involved multiple factions in the Kikyo Sector.

In YE 42, the Jiyuu System is a moderately populated territory serving as a busy urban, industrial, and military center within the Yamatai Star Empire. With the recent return of the Motoyoshi Clan to the region, they have used their influence to drive increased corporate opportunities and have supported initiatives to take in refugees from other regions of the Empire that have been affected by the Kuvexian War. The Jiyuu System also offers many tourist destinations and historical sites.

Jiyuu means “freedom” in Yamataigo (邪馬台語).

The Senator representing the system is Ketsurui Koyama, as of YE 43.

A Message from Ketsurui-Motoyoshi Katsuko

“Welcome to the Jiyuu System! The Jiyuu System is the Regional Captial for the Outer Colonies of the Yamatai Star Empire and is the clan seat for the Motoyoshi Clan. This region has plenty to offer and is a great place to live and work. We welcome the refugees from the rest of the Empire who have been tragically affected by the Kuvexian War.” - Yugumo Corporation Promotion Video, YE 42.

A System With A Rich History

The Jiyuu System was designated as M-1 by the YSS Akuro II, the Flagship of the Fifth Expeditionary Fleet in YE 29. Upon the review of scans from the rest of the Yugumo Cluster, the system was selected to become the Capital System of a new series of Colonies that would secure a new base of operations after the destruction of Taiie by the Sfrarabla Mishhuvurthyar Xhrafuklurp (SMX).

Jiyuu was chosen because of its strategic centrality to other systems in the cluster, making it a potential launching pad for defensive operations in the region. The system is also rich in resources, plenty of planets capable of supporting mining and industrial colonies as well as two inhabitable worldsto support full colonization efforts: Jiyuu III and Jiyuu IV.

The First Colony

The first colony in the system was on Jiyuu III, which was called Tamashii no Jiyuu (“Soul of Freedom”), in YE 29. Settled by the Fifth Expeditionary Fleet and the Motoyoshi Clan, it became the home of millions of survivors from Taiie.

A Brief Independence

In YE 30, the Jiyuu System became the Capital System of the United Outer Colonies, which was intended to be a neutral peacekeeper nation, grounded on a philosophy promoting intergalactic peace through the cooperation of all nations in the known universe. In YE 33, Due to invasion and heavy bombings by the NMX, the Jiyuu System was evacuated by the Star Army of Yamatai.

In YE 34, the system was re-integrated into the Yamatai Star Empire and placed under the protection of Tenth Fleet.

A Return to Brilliance

In YE 34, the Sunflower Corporation began to restore sites on Jiyuu III and made massive improvements and additions to the infastructure of the planetary capital of Tokyo.

Then in YE 41, Ketsurui-Motoyoshi Katsuko, the former Taisho of the Fifth Expeditionary Fleet and the leader Motoyoshi Clan returned and placed a massive financial investment into the System. The former Sunflower Corporation was merged into the Yugumo Corporation and the Motoyoshi Clan funded initiatives to boost commercial and industrial activity in the system. Ketsurui-Motoyoshi Katsuko also made the System the home of the First Expeditionary Fleet.

The Presence of The Star Army of Yamatai

The Star Army of Yamatai has a strong presence in the Jiyuu System:

The system is in the patrol zone of the Tenth Fleet and is the home system of the First Expeditionary Fleet.


In YE 42, Nishitama was relocated to the orbit of Jiyuu III.

Port Jiyuu

Kōdaina Minato-Class

In YE 42 construction began on a Ge-H1-7A - Kōdaina Minato-Class Orbital Installation. Port Jiyuu finished construction in early YE 43 and became the main civilian space-station in the system which would be operated by Yugumo Corporation and the Yamatai Star Empire.

This system has a network of Yomawari-Class NavComm Buoys maintained by the Yugumo Corporation, which provides updated navigation information and other important information to ships within proximity. They were placed in YE 43.

Exports and Trade


The Jiyuu System is connected to the rest of the Yamatai Star Empire by PAINT. Currently in YE 41 destinations through the system are only to Jiyuu III, but future transportation stations are being constructed on Jiyuu IV and Jiyuu V. The Yugumo Corporation offers local service to the rest of the planets in the system.


The Jiyuu System is the home of 1.4 Billion citizens of the Yamatai Star Empire. The population is a mix of Minkan, Nekovalkyrja, Lorath, Human and Nepleslian.
