I was in the earthquake in Tokyo (a few kilometers from Odaiba where that video was likely taken) and I can say I believe it. Out this far from the epicenter it felt very wobbly. It was like my house was on a block of Jell-o. It felt like a 1-3 htz wave. There was a good three minutes of very strong movement and another severe aftershock a 10-20 minutes afterward.
BTW, The girl having a picnic with her boyfriend when the video starts is shouting こわい (kowai) which means "scary!".
