I do absolutely love teaching my students about Japan. I lived there for year and it felt like home, so I think I am biased, however all of my students found the unit to be interesting. Generally students find something about Japan that they were particularly interested in e.g. baseball, sumo wrestling, food, snow, gardens, temples etc. I was searching You Tube and came across some videos that could be used in the classroom.
The videos below are actually an advertising campaign but it does a good job of showing a variety of pictures and places.
