The project, dubbed #dearMoon, will see painters, musicians, and filmmakers join Maezawa on his spaceflight in 2023 (he bought up all the available seats).
SpaceX said previous year that it planned to send two private citizens around the moon in a Dragon crew capsule to be launched by a Falcon Heavy rocket.
He wondered on stage what John Lennon, Coco Chanel, Michael Jackson or Andy Warhol would have created had they seen the Moon up close. After their journey, the artists will be asked to create something inspired by the trip to "inspire the dreamer within all of us", Maezawa said.
Maezawa, a 42-year-old from Japan, is a billionaire who founded Zozotown, an online retail shop. "But I wouldn't recommend doing that, because I think the new architecture, the BFR architecture, is the way to go".
The aerospace company, which is based in Hawthorne, did not say when the flight might occur or how much was paid for the ticket.
After a relatively brief period of teasing the announcement, SpaceX took the opportunity on Monday night to announce its very first paying passenger for a trip around the Moon.
The new BFR moon mission presumably will replace the original Falcon Heavy flight touted by Musk previous year.
A Japanese billionaire has signed up to become SpaceX's first private passenger to fly to the Moon.
The trip into space will provide welcome publicity for his company Zozo, which has ambitious overseas sale targets to be driven by its custom-made private clothing line.
Inc. Chief Executive Jeff Bezos' Blue Origin has announced a lunar cargo delivery service called Blue Moon, which a company executive said could be functional in the next five years and capable of delivering large payloads.
SpaceX will reveal the identity of the passenger on Monday, Sept. 17 at 6 p.m. PT via webcast.
The United States hasn't had the ability to put humans in orbit since the Space Shuttle era ended in 2011.
"It's not 100 percent certain we can bring this to flight", Musk said of the lunar mission.
The spaceship that Maezawa and his team of artists will be boarding will start making short test flights next year.
