This is a great podcast I think: http://www2.jfn.co.jp/owj/index.php (use the link in the upper right if you want to subscribe using iTunes)
The content is very varied and mostly of high quality. Experts and journalists from different fields(economy, health,music, etc.) are invited to talk about what they think is important. The main goal is to introduce issues to listeners and get them interested and thinking where the world/Japan is headed, and to keep meaningful societal debates going. Sometimes the episodes are like interviews, sometimes more like lectures and sometimes more like discussions with no clear interviewer/interviewee roletaking. The level differs, but I would say most of the episodes are quite difficult. The interview episodes are somewhat easier than others.
