There is one.
A Japanese man visited Thailand with his family. Some day they were going to some place with other Japanese visitors by a mini-bus. His daughter, a little girl, was so thirsty that couldn't keep crying. The man asked the driver to stop wondering to buy a bottle of water for her, but the driver pretended not to hear him. The man was worried and got angry, and finally he shouted to the driver loudly :"The child is crying! Stop you car!" The car stopped. All Japanese in the car looked at him weirdly and likely wanted to keep clear of him. Because shouting to others is rude and impolite in Japan.
I assume what will happen in Japan with the same affair. The driver will stop without doubt. Moreover, he will find a comfortable place to stop where the man buy water easily. So there's no necessary to shout to anybody.
This man isn't a typical Japanese, I think. He said on the blog that shouting is a crisis management and there were too many manners in Japan. If he couldn't get water for his daughter, he didn't know what would happen to her. I understand him very much since I've shouted several times at Thailand. They made me do it. People do different actions to suit various environments. That is.
