Star Army of Yamatai

The Star Army of Yamatai is the military of the Yamatai Star Empire. It is an advanced interstellar space force with thousands of starships and millions of soldiers who perform a wide range of strategic, tactical, and humanitarian missions across hundreds of light-years and dozens of star systems.

Star Army Logo

The symbol of the Star Army of Yamatai is the Star Army Hinomaru. The Star Army's motto is “Loyalty, Strength, Wisdom.” It is commanded by Taisho Ketsurui Yui.


The Star Army of Yamatai was established in YE 221) under the name “Grand Star Army” as a replacement for the remains of the Uesureyan Star Empire's Army Of Uesureya and UE Spacy, and the Armies of the Precious Sword, which were the private military of Emperor Kitsurugi Uesu.

In YE 28, the Yamatai Space Self-Defence Force merged into the Star Army of Yamatai and the “Grand Star Army” name was changed to “Star Army of Yamatai” as part of the Military Centralization Act of YE 28.

The Star Army was later enshrined in the The Constitution of Yamatai Star Empire in YE 34.


Wars Fought

The Star Army was a direct combatant in the following wars:

  1. Fourth Elysian War (YE 23-YE 25) as the Grand Star Army
  2. Second Draconian War (YE 24), Star Army universe & Ayenee universe) as the Grand Star Army
  3. First Mishhuvurthyar War (YE 26-YE 30) as the Grand Star Army (until YE 28 when it became the Star Army of Yamatai)

All of these wars that have ended have resulted in a victory for the Star Army of Yamatai. When the future of the Empire is at stake, the Star Army always comes through, although sometimes at great cost.

Other Conflicts & Actions

This section contains other significant military conflicts or events in which the Star Army of Yamatai was involved:

  1. The blockade of Planet Nepleslia in early YE 302)



The Star Army of Yamatai is considered an autonomous military branch of the Yamataian imperial government. It is extremely powerful politically, with a “blank check” budget, the power to declare wars at its discretion, complete freedom from legislative oversight and regulation by the elected senate (according to Yamatai's constitution), and exclusive control over several star systems, making it a sort of “nation within a nation” that is a diplomatic entity in its own right, often making first contact and defining the empire's borders far before the civilian government does. A significant portion of the population (and the Senate of Yamatai) consists of military veterans.



The mission of the Star Army of Yamatai is to ensure the continued survival of the Star Army Wiki, Yamatai Star Empire, and its people and to combat enemies of Yamatai by…

  • Promoting soldier learning and using wisdom to make smart, logical, and efficient decisions
  • When fighting is required, fight with the utmost effectiveness
  • Providing assistance to friendly peoples and forces in need

Area of Operation

The Star Army of Yamatai primarily is based in the SARPiverse where it operates in and around the territory of the Yamatai Star Empire and the greater Kikyo Sector, excluding the space of other recognized sovereign nations. Its reach extends far beyond the YSE's actual borders. In addition, the Star Army has used Transuniversal Teleportation Drive technology to visit and conduct operations in other universes (other websites) such as Ayenee, Python Fleet RPG, Ad Infinitum, and the NationStates forums.


The Star Army of Yamatai contains over a dozen uniquely configured fleets and several dozen organizations that perform functions such as intelligence gathering, personnel management, and logistics.

Note: some of the information in this section is a secret in the roleplay. Consult Wes for guidance.



The Star Army has six active regular fleets, three active long-range expeditionary fleets, and a collection of small, temporary task forces. There are five historical fleets currently inactive. The space fleet is sometimes called the uchuugun 宇宙軍 (Space Army).

Task Forces

Planetary Forces

The Star Army maintains a standing army of several million soldiers who are trained for planetary invasion, occupation, security operations, and planetary defense.

For detailed information, see Star Army Rikugun.

Bases & Facilities

The Star Army maintains an extensive collection of support facilities throughout Yamataian space, and has exclusive control over entire planets and star systems, such as the “Nekovalkyrja homeworld” of Nataria.

For a list of major Star Army bases, see Star Army Bases.


Most Star Army soldiers are either volunteers from the many species of the Yamatai Star Empire, or they are mass-produced soldiers such as the synthetic military species Nekovalkyrja. There are also AI soldiers with robotic bodies. The standard term of enlistment for all species is 3 years.

The most common ways of introducing a character are a transfer via shuttle, or catching a ride on a cargo ship.

Training and Tactics


Most Star Army uniforms are blue-gray with light blue-gray pants with color-coded color panels indicating a soldier's occupation and blue-gray sailor cap with “STAR ARMY” in gold on a black ribbon is used with duty uniforms. A black double-breasted jacket is used for cold weather. Working uniforms are in dark blue with light blue boots, belts, and gloves and a color-coded chest area. On all uniforms, a hinomaru patch is positioned on the right arm halfway between the shoulder and the elbow. A green-colored field coverall is sometimes used over other uniforms.

Armaments and Equipment

The Star Army uses very advanced equipment and is known for its fast, well-armed starships, energy weapons, and power armored Nekovalkyrja. Star Army starships are painted in a ceil color with dark gray details. The hinomaru is marked on the dorsal center-line of Star Army ships and on one or both wings of aerospace craft. Imperial Registry Numbers are on most starships.
