The Kanda University of International Studies (KUIS — or 神田外語大学 in Japanese) will hold its “All Japan Student English Presentation Contest” in December this year. You can find out details about it at their Web site: http://www.kandagaigo.ac.jp/contest/.
Unlike usual speech contests, this presentation contest is more like a Ted talk in that it can be supported by slides and delivered more like a business presentation than a conventional, formal speech. There is even an option to present as a team. This is an exciting opportunity for you!!!
