Yoshinori Miyazawa, a JAXA official said that with the help of companies like Nissin Food Company, JAXA made ' rice balls', seaweed soup, and green tea used in the universe. They are also experimenting with dishes: Japanese beef curry, marinated mackerel, red bean cake .

'However, no one can make sushi on the universe', Miyazawa said . 'I think the shelf life of this dish is a problem'.

To meet the standards in the universe, food for astronauts must have a shelf life of at least 1 year, rich in nutrition, easy to process and eat in a zero gravity environment. Foods that are too loose or have lots of seeds are banned because they can float and affect equipment.

Currently the astronauts on ISS mainly eat food provided by Russia or the US.

JAXA is planning to market " Japanese-style food products " and hopes to provide this food to ISS early next year.
