Yes there is a high chance that while studying in a Japanese University you may strike up a good opportunity at a company by campus placements. Also it would increase your international exposure and give you good life lessons.
Japan education system is much advanced and there you will definitely get a whole lot of good opportunities.
Also the companies would sponsor your visa in Japan so you wont be having much problems with the Embassy.
