The accommodation will be spartan and the food unpalatable, but stunning views are guaranteed on Japan's most expensive package tour, unveiled on Thursday.
Japan's biggest travel agency will charge 2.2 billion yen ($20 million) a head for a week-long tour to the International Space Station, travelling on the Russian Soyuz spacecraft, Kyodo news agency said.
JTB Corp. will offer the tours from October in a tie-up with Space Adventures Ltd. of the United States, which has already sent two tourists into space, Kyodo said.
Would-be astronauts will be required to undergo six to eight months of preflight training.
Other itineraries in the pipeline include a trip around the moon for 11 billion yen and a zero gravity tour, which will take participants to an altitude of 100 km (62 miles) for a relatively inexpensive 11 million yen.
