The rocket dubbed BFR has not been built so any flight presumably is at least several years away.
SpaceX is now prototyping the spaceship and other BFR hardware inside a 20,000-square-foot tent at the Port of Los Angeles - at least until a much bigger permanent facility is completed. "I choose to go to the Moon", he was quoted as saying.
The mission is planned for 2023, and would be the first lunar journey by humans since 1972.
SpaceX said it has signed the first private moon traveler, with some changes to its original game plan.
Speaking to the crowd, Mr Maezawa said the possibility of flying to the Moon was a "lifelong dream".
The BFR will stand about 387 feet (118 meters) tall, and both its rocket and spaceship components will be reusable.

"He's paying a lot of money that would help with the ship and its booster", Musk said on Monday. The SpaceX and Tesla CEO framed the trip around the moon as an important part of the company's larger mission to colonize Mars. SpaceX plans to launch the first unmanned mission to Mars by 2022 - a goal Musk himself has described as "Ambitious", with a sight to putting the first humans on the red planet by 2024.
He said the BFR is still in development and will make several unmanned test launches before it takes on passengers.
SpaceX founder Elon Musk tweeted that Yusaku would be "bringing eight (brave) artists & cultural figures with him on the journey around the moon".
SpaceX has had a string of successful rocket launches, but that has been overshadowed by the struggles of Musk's Tesla electric auto company to deliver and his behavior.
However, Musk said that rocket would not be certified to carry people, which ruled out a round-the-moon trip on a Falcon Heavy.
Earlier in the day, Musk was sued for defamation by the British driver he had accused of being a "child rapist" and pedophile via tweets and emails to media.
