Background Information Edit
The name and registry came from the studio model. The class name, which appeared in the Star Trek Encyclopedia (3rd ed., p. 255), was provided by production sources.
In addition the Star Trek Encyclopedia stated, "the Kyushu was named for one of the four main islands of Japan, where a Japanese orbital launch facility was located."
The Kyushu was referenced in a line in DS9: "Emissary" that was later cut. According to the script, the ship's name was pronounced as "kee-OOSH-ooh". 
The Kyushu was also mentioned in the video game Star Trek: Borg as the USS Righteous monitored the battle of Wolf 359.
