I was traveling in Okinawa for a month and I took a ton of great video. I mostly just videotaped things and larger crowds of people, but didn't get too much grief for anything. I was told that I couldn't videotape at Shuri castle, so I said sorry and stopped and it wasn't a big deal.
I've been editing my video into short 90 second to 2 minute podcasts. I have a bunch more to edit. There should be about 25 episodes when I am done. Check it out...
