Not sure if all commuters here in Toronto would stay behind the barrier in the rush-hour if platform was crowded.
When I first visited Japan, very few platforms had barriers. More and more stations are getting them. The barriers have gates which open after the train has stopped, but are otherwise closed. However, there's still stations with no barriers. Most of the stations with no barriers that have trains passing through at speed have sidings for the platforms so it's not possible to fall in front of a train at speed.
These platforms are at Shin-Osaka where all trains stop, so there's no automated barriers.
The Japanese are generally very good at forming lines and patiently waiting for people to get off the train before trying to board. I was quite embarrassed at New Year to see the utterly uncontrolled way people behaved in Sydney when boarding trains - trying to force their way onboard when people were trying to get off.
