Two persons were crossing the street together

The pedestrian crossing was well seen from where I stood. During the traffic light was green, the pedestrians were going up and down below my eyes. In the meantime, a couple appeared into my sight and started to cross.

I didn't know whether it was a Japanese specific behavior or not. However, it was few people who were crossing the street during the red signal even though there were no cars. And I remembered a French football manager said that Japanese players were too amenable. I thought it might be one of the reasons why the Japanese company produced innovative goods.
