Three sources from the rocket space agency told the satellite news agency that a Japanese national could be the next space tourist to travel to the International Space Station aboard the Russian Soyuz spacecraft in December 2021.
One of the sources said the tourist was Japanese.
Two other sources also believe it is a Japanese citizen. A fourth source said japanese space meals were being booked for space tourists.
Tony Quine, a British aerospace expert, posted on the social networking site that he was a Japanese singer.
Space Adventures, which runs Space Travel, did not comment to the satellite news agency for comment.
American Space Exploration was the only space travel company not long ago. Between 2001 and 2009, under a contract with Space Exploration, seven tourists, including American Charles Simone, flew twice on the Soyuz spacecraft. In different years, their ten-day flight cost $20 million to $50 million.
