>>1020298Last time I rided Shinkasen from Osaka to Fukuoka at night when a long Japanese holiday start. Didn't made advanced booking as that trip were not planned beforehand, all reserved seats are fulled so the only option is non-reserved. Hundreds of people crowded on Shinkansen platform waiting to board shinkansen especially in non-reserved section, but even that was only a fraction of what happened in the video.
As those trains are down from Tokyo so they're almost fully seated, so passengers get on the train without reserved tocket have to stand on the train.
It wasn't fully packed as in you can still use your mobile phone on the train as almost everyone board the train carry a luggage so that freed up some space but even the entrance/exit section between two cars are filled with people.
At least quite a few people drop off at Hiroshima/Okayama and freed some seats up so it's not needed to stand 3 hours straight...

>>1020224I read that back in 1970s some trains are so fullu packed that passenger's safety is threatened by it. They said there are so many passengers that train windows could be broken by the pressure of passengers. Not sure about is that hypothetical or have that actually happened.
