After successfully completing a "Research Cosmonaut" training course at the Yuri Gagarin Cosmonaut Training Center in present-day Russia, Akiyama launched aboard the Soyuz TM-11 mission to the Mir space station on 2 December 1990 along with mission commander Viktor Afanasyev and flight engineer Musa Manarov. During his time aboard Mir, Akiyama gave live reports each day documenting life aboard the station. He returned just over a week later aboard Soyuz TM-10 along with Gennadi Manakov and Gennadi Strekalov on 10 December. Akiyama's mission marked the first flight of a person of Japanese nationality in space as well as the first commercially sponsored and funded spaceflight of an individual in history. Akiyama was also the first journalist to give live reports from space.
