MOHRI Mamoru was born in 1948 in Yoichi Town, Hokkaido. In 1985, he was selected to be Japan’s first-ever astronaut, and in 1992 was the first Japanese scientist to board the Space Shuttle Endeavor. Using experimental equipment co-developed by Japan and the US, he carried out on-orbit experiments that made use of the characteristics of the space environment. In 2000, he once again boarded the Space Shuttle Endeavor, this time on an earth observation mission.
