I found by chance, while checking my old iPhone. That I did record a commemorative Shinkansen series 700 on its last days of operation at Shin-Osaka station. What I do remember about this video, is seeing plenty of people at the platform across while I was waiting for my train to Tokyo.

I noticed on few of the video frames, that the side of the Shinkansen had the following wording: SHINKANSEN Series 700, ありがとう LAST RUN 2020.3.8.

The actual last run did not occur because of the COVID-19 outbreak. I took the video on Feb 29th 2020.
