Akiko is a star system in the Bard Cluster. It was named for Shimizu-Motoyoshi Akiko (清水本吉明子).

Akiko was originally colonized under the control of the Fifth Expeditionary Fleet (: When?) and protection until YE 29 when the Mishhuvurthyar conquered the Bard Cluster. It was then under the control of the Mishhuvurthyar until their defeat in YE 30.

In YE 30, Akiko was released to the Yamatai Star Empire's control as part of the Intergalactic Armistice Agreement of YE 30 (IAA) signed at the International Relations Conference of YE 30 at the end of the First Mishhuvurthyar War.

After the Mishhuvurthyar were driven off the system was once again under the control of the Yamatai Star Empire . The system was under the control of the Fourth Fleet, and it was re-colonized primarily by former Yamatai Star Empire soldiers. It was named after the Taisho Shimizu-Motoyoshi Akina (清水本吉明菜)'s daughter Shimizu-Motoyoshi Akiko (清水本吉明子).

In YE 32 the colony was abandoned when the NMX forced the Fourth Fleet to have to consolidate its holdings after losing a major portion of their fleet in two engagements. Prior to abandoning it the Fourth Fleet damaged all structures and equipment so they could not be used by the enemy.

In YE 34 the Scientific Studies Service (SSS) deployed a Ke-P6-01a Bisen Lighthouse on the surface of the planet at the request of the Star Army of Yamatai.
