I just got the results from my embassy and I GOT IN I can't believe it !! In the mail, they told me that the ministry will now deal with the unis I applied for to see if they can send me in, otherwise I'll be placed in another one. But there's nothing conditional in the mail, they say:
"The final decision taken by MEXT will be irrevocable. You will know the university you will be placed in at the latest in early august. By this time, we will ask you several documents you will have to send us as soon as possible. We will explain to you how to get the visa and further information concerning your stay in Japan. Please know that a withdrawal is not desirable. However, if such a situation would be unavoidable, please send us a handwritten, dated and signed letter as soon as possible. A meeting where former MEXT scholarship's applicants will be invited will take place on July so they can convey information related to your stay in Japan."
As you can see, it seems to be quite official, I guess that if in France we got something quite official, that means that for the other people who got in all over the world, your chances to get rejected after the 2nd screening are extremly low.
Just so you know, it seems that all the french applicants who passed the 1st screening (5 people) got in, I'll be sure on july during the meeting.
Good luck to the other who are still waiting !
