History and Background

The clan was formed by Ketsurui-Motoyoshi Katsuko and Shimizu-Motoyoshi Akina (清水本吉明菜) in YE 28. The clan has a rich history which is entwined in both the Yamatai Star Empire and the Star Army of Yamatai. It is the only clan other than the Ketsurui Clan to rule the Star Army of Yamatai. In YE 30, Ketsurui-Motoyoshi Katsuko became Empress when she succeeded Kitsurugi Uesu. Her time on the throne was short, and was ended with her own resignation after members of her clan deserted and betrayed the Yamatai Star Empire to form the United Outer Colonies. The part of the clan that remained in the Empire became affiliated with the Ketsurui Clan.

The clan remained separated into two parts; Yamatai no Motoyoshi and Jiyuu no Motoyoshi until YE 41 when Ketsurui-Motoyoshi Katsuko reunified the Clan. Her plans for the future unfolded quickly which brought the clan into a surge of rapid growth.

Traditional Holidays and Ceremonies

These holidays are celebrated, in addition to all other Holidays in the Yamatai Star Empire, by all members of the Motoyoshi Clan. Motoyoshi Mon

Tsukimi 2日8月 The celebration corresponds to the harvest moon of the destroyed colony at Taiie. Reminiscent of colonist farmers that worked the colony's fields it is a celebration of autumn that is still celebrated by the Motoyoshi. The celebration generally includes feasting within the volumetric captured images of the fallen world's moon, accompanied by soft flowing flute music and tranquil gurgles of water features.
Lantern Festival 17日2月 to 20日2月 Elaborately decorated lanterns made by clan members are put on display. These designs integrated with all kinds of creative expression; painting, flower arranging, carving and sculpture creating. Lantern displays are judged and the winners are honored by being permitted to keep their display up after the end of the festival until the next year.
Unity Festival 15日 3月 Added in YE 41, this festival celebrates the day of forgiveness between the Jiyuu no Motoyoshi and the Yamatai no Motoyoshi. Members of the Motoyoshi Clan gather to reflect on the healing of the divisions that nearly destroyed the clan. It is generally held at one of the Clans holdings on Jiyuu III or Yamatai (Planet).

Unifying Motoyoshi Philosophies

These unifying philosophies govern the actions of the Motoyoshi.

Motoyoshi Kazue

Imperialists As of YE 34, the Motoyoshi have become strict imperialists, their vision for the Yamatai Star Empire is for the re-centralization of absolute control to the throne and the Star Army of Yamatai. They believe that the Senate should maintain an advisory role to the throne but not be granted actual power. Despite their desire for re-centralization of power, they do support the Ketsurui Clan and the current rule of Empress Himiko I even though they do not back some of the more democratic policies of the current rule, specifically the policies which were triggered by the formation of the United Outer Colonies.
The Imperial Way See Imperial Way Faction. The Motoyoshi support a movement referred to as 'The Imperial Way'(皇道派) which desires a more military-minded government. They believe that a stronger military-backed government will free the empire from liberal-minded politicians seeking the decentralization of power. This has been supported in the past via the formation of the original Bakufu prior to its corruption.
Nekovalkyrja Supporters The Motoyoshi believe that the Nekovalkyrja are the greatest species in the known universe. They do believe in intergalactic cooperation, however under asymmetrical terms. They believe that the Yamatai Star Empire has made too many concessions in the intergalactic community, blaming some of the clan's own previous policies for some of the problem. The clan is not completely against other species or nations, believing that there are several nations who have relations with the empire that are beneficial, however, there are several to which they hold a vehement animosity such as the Freespacers. Since YE 40, through relations with the Lorath Matriarchy2), the Iron Company and the Mining Guild much has changed.
Star Army of Yamatai Tradition The clan has entrenched its upholding and belief that the military elite is a necessary and needed echelon of power within the Empire. Military leaders such as Mistress-Taisho Ketsurui Yui and Taisho Kessaku Irim are regarded in the highest of honors, along with their own Taisho Ketsurui-Motoyoshi Katsuko. The Motoyoshi believe that the military's elite echelons should remain untainted by liberal-minded politics.
The Mistress-Taisho The Motoyoshi strongly support the Mistress-Taisho Ketsurui Yui and her direct leadership over the Star Army of Yamatai. Many Motoyoshi has an almost spiritual view of Yui, seeing her as the guiding force of Nekovalkyrja power and philosophy.
Sensou Sensou ( 戦争) - War is the expression of Imperial power and justice. It is the fundamental protection of the Empire and the Star Army of Yamatai is the most prestigious way of life for Nekovalkyrja. The Motoyoshi view war as an art-form in which must be executed with strategy, courage, and ferocity. To play a role in the evisceration of the empire's enemies is a high honor and should be conducted with grace and power to achieve victory in the name of the Empress.
Unorthodox Measures The Motoyoshi strategy in warfare tends to be unorthodox at times. Utilizing units and personnel in actions that are outside of their normal conduct to gain an advantage.

The Clan Virtues

The Motoyoshi philosophies are very reminiscent but not limited to the Confucian ways of thought. Motoyoshi Kazumi

Clan Virtues
The State of Virtue The Motoyoshi are very concerned about the nature of its members. With the clan's past, the leadership is very concerned with its own practices as well as those within their influence. Members are expected display : integrity, honor, honesty, loyalty, kindness and forgiveness while being reverent and respectful to those who are their superiors and peers. The clan also promotes the self imposition of shame, for individuals to be able to judge their own actions to be right or wrong and seek or inflict measures to correct their actions when in error.
True Relationships The clan's beliefs state that the highest of relationships is the one that exists between Nekovalkyrja and the Yamatai Star Empire in which the soldier serves as the imperial hand and that their actions, therefore, reflect the Empire. Focus is also placed upon the relationship between Nekovalkyrja and their clan in which altruism is to be cultivated between members.
Loyalty After the corruption created by the Jiyuu no Motoyoshi a great intensity was placed upon the Motoyoshi's loyalty. Loyalty to the Empire is place first and foremost, then loyalty to the clan and the military.
Self Improvement Within the clan, it is encouraged for members to seek to expand themselves as individuals. The greatest focus is placed upon the achievement of rank within the Star Army of Yamatai and to excel within one's occupation however, members are also encouraged to divulge in philosophy, literature, and creative arts.
Place in Society The Motoyoshi believe that the clan's true place is to provide strength to the Imperial Family, to serve as dedicated soldiers within the Star Army of Yamatai. In general, civilian life is discouraged unless that career path is considered still within the higher service of the Empire or the Clan.

The Motoyoshi Clan's influence and power are concentrated within the Motoyoshi Colonial Sector. The Colonial Sector is located in the galactic-east of the Kikyo Sector and is sometimes referred to as the Eastern Yamatai Star Empire. The region is known for its rich resources and hard-working citizens and has been under the colonial management of the clan's Yugumo Corporation since YE 41 which marked the Motoyosh Clan's return to the region.

The Motoyoshi Clan has a deep connection to the region as refugees settled it from the Bard Cluster and survivors of the Battle Of Taiie. To return to the region after the fall of the failed nation of the United Outer Colonies and play a vital role in the new stability and prosperity of its people is regarded as an honor and a duty, due to rouge members of the clan have been responsible for a tremendous loss of life and the emergence of Tange terrorism.

The Bard Cluster

The Bard Cluster holds special importance to the Motoyoshi Clan. The region was explored and colonized by the Fifth Expeditionary Fleet and served as their home up until the Battle Of Taiie in YE 29, which resulted in the destruction of the Taiie. The Taiie Nebula was left as the remains of their home. The Clan and citizens in the Motoyoshi Colonial Sector make pilgrimages to the nebula during Tsukimi held every year on 2日8月 of the Yamataian Calendar.
