About the show:
"...this program explores many aspects of Japan, both traditional and contemporary: arts, sports, entertainment, food, technology, nature, etc."
I try to watch the show live on NHK World when the episode looks interesting. Last week it was about convenience stores in Japan; this week (Thursday, i.e. tomorrow) its about used books.
You can also find episodes on youtube, etc. Here's a sample - it's the episode on vending machines (I believe it's from season 5 of the show). I love that udon machine - it's so fascinating!
