The Kōdaina Minato-Class orbital installation is amongst Geshrinari Shipyards oldest station designs – and is the only one so old still in active service. It has long been utilized by the shipbuilding firm in an industrial capacity, providing many of the requisite construction and fabrication facilities needed to produce starships. Due to their size, existing stations of this class are under constant maintenance and are constantly upgraded and refitted in order to keep technological parity with newer, more recent station designs. The 7A variant is the latest fully-updated incarnation of the Kōdaina Minato-Class, made available in YE 33.

These vast structures are self-supporting arcologies, major centers of commerce, industry and home to millions of residents. Typically, these stations are only built in star systems with a high degree of development or significant material resources. The foremost characteristic of this particular station class is its versatility – each Kōdaina Minato station is a massive space-borne colony with fabrication facilities capable of crafting virtually all types of starship, advanced equipment, and materials. They also have large interior spaces dedicated to agricultural production, hydroponics and aeroponics. They have a total of 654 docking bays of varying size – many of which are able to accommodate smaller stations like the newer Sanza-class shipyard, as well as some of the largest existing types of starship for the purposes of construction or maintenance. Whilst this station class is also capable of limited sub-light maneuvers and possesses the ability to reposition itself with its hyperspace fold system – it is intended to remain in a fixed position within a high traffic area. The class designation 'Kōdaina Minato' means 'Vast Harbor' in Yamataian.

The earliest Kōdaina Minato station was built by Geshrinari Shipyards during the companies first decade, giving them the industrial foundation required to construct larger classes of ships and new stations. Because of their size and prodigious cost, they were intended to last indefinitely – though each station requires constant maintenance to ensure it is kept in full working condition. With Geshrinari Shipyards recent refurbishment of their shipbuilding facilities in YE 33, the firm has once again updated their design to incorporate the latest advances in their technology – they also have begun refitting the existing stations to the updated 7a model.

The Kōdaina Minato design has never been a restricted technology and Geshrinari Shipyards has marketed the design to other civilian organizations, commercial entities and friendly government agencies – though due to the sheer cost and resources required to build these structures, they remain understandably rare. Those stations owned by corporations and companies – due to the large civilians populations – are usually jointly administrated with whatever government the commercial entity is most strongly affiliated with.

In terms of size, the Kōdaina Minato is comparable to the Abwehran COSS-Type and Origin Industries OOSS-Type. The station reaches 43.56 kilometers at its widest points, whilst from top to bottom it reaches a height of 30.97 kilometers. The upper wheel-like section of the station houses the Kōdaina Minato's six largest docks and most of its fabrication facilities, and is centered around the main residential sector and the primary command and control tower. Beneath those areas are the primary docking rings housing six-hundred docking bays in a range of sizes. Beneath the top three docking rings and at the same level as the two lower docking rings are the stations six fabrication armatures. The fabrication arms each have eight docking bays capable of accommodating all but the largest ships. Extending out of the bottom of the station are an additional six armatures, which primarily contain warehousing facilities for storage and the stations support systems. In-between the warehouse arms are additional, smaller residential sections.
