Meet Yusaku Maezawa

Yusaku Maezawa (MZ) flew to the International Space Station in December 2021. He was joined by a Russian mission commander and Yozo Hirano. One of MZ’s goals was to find out ‘what’s life like in space’? With the assistance of Yozo, MZ documented his daily life on the ISS and shared it with the world on his YouTube channel.

MZ and Yozo became the 8th and 9th private citizens to fly to space on missions arranged by Space Adventures.

12 days on the International Space Station

MZ and Yozo stayed on board the International Space Station (ISS) for 12 days. The ISS is humankind’s only outpost in space, circling about 400 km above the Earth’s surface.

Soyuz spacecraft

They flew to space on the Russian Soyuz spacecraft, launched on a Soyuz rocket. This spaceflight system has been in operation for over four decades.

Space Adventures guided the crew

Space Adventures guided the crew through their training program at the Gagarin Cosmonaut Training Center in Star City, Russia, and assisted with the development and implementation of their mission program.

Launched on December 8, 2021

The mission launched on December 8, 2021 from the Baikonur Cosmodrome in Kazakhstan, the launch site for all Russian human space missions since Yuri Gagarin’s first ever flight to space in 1961.


Yusaku Maezawa, or MZ. is a Japanese e-commerce entrepreneur and world renowned art collector. After high school he became a drummer in a rock band, and an avid record collector. His record collection became the foundation of his first company. His mail order business transformed into an online business, which lead him to own and run Start Today, a publicly traded online retail clothing business, which he eventually sold to Yahoo Japan in 2019.


Born in Ehime Prefecture, Japan in 1985. Yozo joined ZOZO Co. Ltd shortly after graduating from university, in charge of management and casting director of the photography team. After leaving ZOZO, he started working as a producer and manager for MZ’s private projects, including filming for MZ’s youtube channel. On the ISS, Yozo will be responsible for filming MZ during their stay.
