Japan space tourist says moon training 'shouldn't be too hard'

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 work day 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."
