I read the comments on this page. It is good that you guys started to look for scholarships.
The first thing I think that is needed is to look at yourself.
-What further study and career do you want. What are your skills? Every year lots of applicants, who do not possess enough basic English skills, apply for the scholarship. Every year lots of scholarships who get the scholarship realize that they find themselves in Japan with no clear plan for their future. If you just want a decent education, but don't have the money for it, there are other options than Japan and other scholarships too. Consider more than one option.
-When you decided that this scholarship is what you need, think about your strengths and weaknesses. English skill, Japanese skill, skills in your field of study, connections in Japan, ... If you think they are enough or will be enough to receive this scholarship, apply. Don't lie to yourself and apply if you know you are not worth it. Every year people apply for the third time to get this scholarship and they do not get it.
-Thirdly, if you want the scholarship and if you feel you are good enough, you need to prepare. Being well prepared is the key. Do this by preparing yourself and doing things yourself. Write your research proposal yourself and then have it checked by people. That way you can see your mistakes and learn for the future. Don't do it the other way around. If someone else wrote your proposal, you'll find yourself in Japan not being able to live up to the task. Reading about it on the internet and asking questions is not bad, but at some point you'll just have to trust yourself to communicate with the embassy and rely on their information.
@krazyneko: If professors don't reply, it can mean many things, but you can probably also know the reason yourself.:
-You mailed them in English and they do not speak English
-You mailed them in English, but your English proficiency is lower than they regard sufficient to take their program
-The subject line of your e-mail looks like spam
-They didn't like your research proposal and didn't mail you back, because you didn't ask them to do so if they rejected you.
-They think your research proposal is not in their field of study and you didn't ask if they could help you even if they didn't become your supervisor.
-They don't reply to people unless they already obtained the scholarship, or unless they have been accepted into their school. This way they don't have to bother to check everyone and risk having to take care of below level students.
@koushou: It depends on the other participants. If they are all honors students, you risk having a disadvantage. Your grades are relevant, because they are numbers and numbers are easy to compare, but if you needed honors, the application guidelines would have said so. They say: outstanding academic performance. This means both your grades, the level of your academic institution and anything else related.
