Have you guys considered doing a series of lessons on each of the prefectures in Japan? Japan is a surprisingly diverse country and it would be nice to hear a little about that.
I know the dialect class was sort of like this, but It might be interesting if you could talk about each prefecture in Japan and some stuff that the prefecture is well known for. The contents could include meibutsu, celebrities, or places. Since you guys are based out of Tokyo, it should be relatively easy to find people to come in and talk about their home prefectures.
I agree! I think it would be a very good source of inspiration for travellers who don't want to go where "everyone else" goes.
And of course it would be nice for others to know that there is more in Japan than only Tokyo
