SpaceX previously announced plans to eventually use Falcon Heavy to launch paying space tourists on a trip around the moon, but Musk said in February he was inclined to reserve that mission for the BFR.
The moon hasn't seen any human visitors since 1972 and NASA's last Apollo mission.
And if you were wondering, "We'll do a bunch of test launches before having any people on board", Musk said. "These are all artists that I adore".
His dedication to art also extends to the Moon: Maezawa announced on Monday that he will foot the bill for six to eight artists to join him on his travel in space in 2023.
Maezawa hasn't selected which artists will join him on the four to five-day journey, which will send his craft around the Moon and back to Earth.
The 42-year-old entrepreneur says he wants his guests to be inspired to create once they return to Earth.
The exact price that Maezawa paid has not been released, although he says that it will be free for the accompanying artists.
Japanese billionaire Yusaku Maezawa stood before the audience gathered at SpaceX headquarters Monday evening and was greeted by cheers when he echoed a line from a famous speech by President John F. Kennedy, proclaiming "I choose to go to the moon".
Maezawa then said, "Yeah, yeah, yeah - please, please".
Looping a human around the moon is just the first stage of a plan that is targeted on the moon, Mars, Jupiter and beyond.
Musk said Maezawa had outlaid a significant deposit and would have a material impact on the cost of developing the BFR, which he estimated at about $5 billion.
Yusaku Maezawa talks about his plans to travel to the moon during a SpaceX press briefing on September 17, 2018.
"It's not 100 percent certain that we succeed in getting this to flight", he said of BFR.
The amount Maezawa is paying for the trip was not disclosed, but he told Reuters the total sum was "much higher" than the cost of a Basquiat painting.
No guidance has been given on when the moon flight could happen.
Maezawa made his fortune by building up Start Today, an e-commerce business that includes a popular online clothing site in Japan.
While most of us may not have the funds to take a trip to the moon for our next holiday, however, if one day it becomes affordable, we would need to know what to pack.
As the event ended Someone ask Musk if he will go into space.
This isn't the first time Musk has vowed to send tourists around the Moon.
Aerospace experts who follow Musk and SpaceX's activities suggest that there could likely be more iterations of the BFR design before the company's first lunar voyage lifts off the launch pad.
SpaceX gave no details of the flight but said it would be "an important step toward enabling access for everyday people who dream of traveling to space".
