Billionaire Japanese tycoon and future space tourist Yusaku Maezawa's training to go the moon should not be too tricky, he joked Tuesday, adding that he planned to use free time from his six-hour workday to squeeze it in.
The 42-year-old Maezawa paid an undisclosed sum for a ticket on fellow tycoon Elon Musk's SpaceX rocket around the moon as early as 2023 and the passionate art collector also plans to take around half a dozen artists with him on the trip.
"It hasn't been decided yet what training I will need to undergo but Elon Musk has said it shouldn't be too hard," Maezawa jested, adding in Japanese, "I believe English will be a must."
Asked how he could fit astronaut training around his already hectic schedule, he said he adhered to his own company policy of working a six-hour day and devoting the rest of the time to personal projects.
"I don't go to work from morning to night. I'm there three or four times a week and I try to go home after six hours," Maezawa told a packed news conference in Tokyo.
First announced in 2016 and estimated to cost $5 billion (S$6.9 billion), the BFR was touted as the most powerful rocket in history, even more potent than the Saturn V moon rocket that launched the Apollo missions five decades ago.
Maezawa said he had received "safety guarantees" that allowed him to be able to invite the artists along on the trip, although he confirmed he had not yet begun negotiations with potential fellow-travellers.
He said he was most looking forward to seeing the entire Earth from space.
"I look forward to getting close to the moon. I would like to see the Earth in full view... To see it with my own eyes, just thinking about it now makes tears well up in my own eyes," he said.
Maezawa is chief executive of Japan's largest online fashion store and is the 13th richest person in Japan, with an estimated fortune of $2.8 billion, according to business magazine Forbes.
He did not deny there were some commercial interests behind his decision to pay for a ticket to the moon, as the exposure has hugely boosted his profile.
"I was formerly known as 'Maezawa the fashion guy' and now its been updated to 'Maezawa, who's going to the moon'," he said.
