MEXT is a scholarship offered globally by the Ministry of culture, sports, science, education and technology of Japan (Monbukagakusho scholarship). Every year the notification comes out in training circular page of indian railways website. All other details can be found over there.
However I would just like emphasise on the fact that it was originally available exclusively to railway engineers, meaning those who have joined railways through IES. I wrote a detailed letter to the Secretary, RB and finally MT had assured that traffic officers have been made eligible. i request all of you to avail the opportunity if you’re eligible.
Best of luck.
