Japanese billionaire Yusaku Maezawa tweeted on Monday that he plans to make a "big announcement" related to space after a meeting with SpaceX owner Elon Musk.
Yusaku Maezawa, founder of online fashion site Zozo Inc, completed a tourist trip to the International Space Station (ISS) on a Soyuz spacecraft in December last year and plans to journey around the moon with Musk's rocket and satellite company SpaceX in 2023.
The 47-year-old entrepreneur tweeted that he had held an online meeting with Musk and "can now make a big announcement about space on December 9".
The space enthusiast will likely become the first private passenger on a SpaceX moon mission with a week-long fly-by planned for 2023, as commercial firms including Jeff Bezos' Blue Origin usher in a new age of space travel for wealthy clients.
Maezawa made his fortune founding the online fashion retailer Zozo which was bought by Softbank Group Corp's internet business.
Following Maezawa's tweet, shares in Inclusive Inc which provides space-related business utilising satellite data, soared 11.7 per cent to close at 1,171 yen.
