Nogami was a second lieutenant in the Imperial Japanese Army in the early 20th century. In 1937, Nogami was one of three hundred Humans abducted from Earth by an alien species called the Briori and taken to an unnamed class L planet in the Delta Quadrant. Nogami and seven of the other abductees were put in cryogenic stasis and came to be known to the abductees' descendants as "the 37's". They remained in stasis until the crew of the USS Voyager revived them in 2371.
