The train ride was atypical the whole way, the train would've stopped randomly and carriages were very full. We even got to see some angry men loudly complaining and tapping the train driver's door; quite a rare sight in Japan. We later realised it was the small quakes that had struck before the big one.
We arrived in Tokyo delayed, we had some food around Ueno station, just when we were about to board the train the big earthquake struck. It was loud at first, then slow rolling. But it went on for too long. You know it's a big one when the local middle school students are cowering and some even started screaming. The station's lights shorted from swinging so much and some spark flew as well. Then news came, the bullet train would be cancelled, in fact all trains were cancelled. We walked around aimlessly trying to find accommodation for the night but couldn't, everyone was stuck in Tokyo. It was quite funny to see even when almost everything's sold out in convenience stores, same food/drink were left alone everywhere.
At the end we sat and slept in a lobby of a 5 star Hotel nearby Tokyo train station who were nice enough to invite all the people still out and about at 2am. The next morning the bullet train was declared fit to run again, phones started working too, and on our way to catch the train to Osaka, we received a call from our accommodation in Osaka, the staff simply said your luggages arrived yesterday and are here waiting for you.
