Thank you! Your Japanese is much better than mine! I can read it but only with the help of a dictionary. Anyway, in answer to your question... I have no definitive answer. I don't know if it's okay or not. I do not ask and most people are not even aware they are photographed, much less that their photos are shown. However, I feel that I don't portray people in any compromising situations (usually) and I'm not photographing anything you couldn't have seen in a public place had you been standing where I was standing at that moment in time and space. Essentially, you can experience my experience vicariously through these photographs. If you feel this is wrong, then it may be wrong. But I certainly feel there is a moral ambiguity in what I do.
I don't think you are doing anything wrong. The pictures you post are flattering and respectful. It's not like she's up on a billboard. Having said that I feel really self conscious taking pictures of others for some reason.
