If you want to study here you are going to have to pass the entrance exam and you need to know Japanese for that and it is quite difficult. I don't know if there are an exchange programs where you are and what is required, but you could check that out.
You best option is to contact a University and ask them what is required and what options you have. As for which ones , you could try the Osaka University of Commerce ,or the Osaka City University. Sorry I only know place around Osaka.[]
