Japan has about 800 universities. And countless Vocational schools and Language Schools (to integrate higher education institutes, you may have to first study at a Language School). As the Japanese government has pledged that it wants to double the number of international students by 2020 (to reach 300,000), institutions have more and more programs for foreigners. International students are really welcome, if not wanted. For example, that will shows in the fact that more and more programs in Japan start in September to accommodate foreigners, instead of April. Whatever your field of Education, whatever your skills, the possibilities are almost limitless. The choice is truly yours.
