It seems that based on the information I heard before, neither of them is very good. Good is normal university, after all, this is somebody else's old major. The media is a bit like numbers. It seems that the website construction was not good a few years ago. Minda should be better than Nakagawa.
You can have a general summary by looking at the teachers and hardware facilities on the department pages of the websites of these two schools. You'd better go to the post bars of two schools and ask them. If all the negative accusations come out, you will know that the school is dying.
