While I would agree that to penalize foreigners for something that cannot be changed for a visit to their country does not put the Japanese in a good light, and in this case when the person is obviously not native it is insensitive on their part to ban them from otherwise public places.

However, to blatantly disregard the host country's customs and expectations of behavior is even less excusable.

Both are wrong, but when you are a visitor you have chosen to be there and there is a implied agreement to abide by their rules. This applies in any situation short of one that would cause injury.
