First day of summer semester

So here I am in class, it's the first day of summer semester at Temple University Japan. Been here almost a year now. Kinda curious about what we will do in this Tokyo stories course. Already thinking of ideas for documentaries or multi-media presentations. Some ideas I have are "Sex in japan", this is quite a broad topic but perhaps I could narrow it down to something like the sex industry....hmmmm. Or "Cram Schools" and their effects on kids personal lives. I don't know, what do you guys think out there? What are some things you'd like to know about Tokyo?
