This article says that Kansai University of Foreign Languages in Hirakata, Osaka, will send some of its students who have studied abroad for some time to teach English at local elementary schools. The article says that they will be teaching "English conversation and international communication."
The local Board of Education says that the experience will help primary school teachers by giving them "teaching know-how" from universities.
Nice idea. It would be great for the children to hear about young adults' experiences abroad and encouraging stories. I'm not convinced about the rest.
