found a link to this from an unrelated website but it might explain the issue.

It seems that because of Japanese copyright law, Japan hasn't taken up YouTube Red, and in response, YouTube is blocking Japanese content. I think YouTube Red has started up in Australia about the same time these videos became blocked, so I guess that explains it.

I guess the net effect is that it turns me off YouTube Red altogether.
