First of all, we could sit on a priority seat if nobody people wouldn't need to sit. It means the seat doesn't signify that healtyh people must not sit on, but if only there are people who need to sit, we should hand over.
Secondly, I think the seat give me the courage to hand over my seat to worrying people. If there aren't the seat, a lot of people (who want to give a seat) couldn't found courage, I think. That is why, I think the priority seats give people who couldn't find courage to give a seat to eldery or handicapped people.
For these reasons, I think Japanese have to have priority seats in a train.
