Though I contacted NHK WORLD Japan about the possibility of this airing on their channel, it is not in their program list. That is what I expected. My only question now is how I will be able to view this special program outside of the US?

The best options would be a repost of the concert online, a DVD, or digital download. I am not sure if any of those options will be available. Is it possible that NHK Japan will upload the concert (if not then segments of it) on their website?

Thanks.
