Several disc shaped objects seen during photograph at Japanese train station in TokyoI was riding the train home from Ikebukuro Station and glanced out the window and noticed how beautiful the sunset was. Once I got off of the train at Shiinamachi Station, I noticed several people standing at a window taking photos. I then went to the window and noticed that everyone was taking pictures of the beautiful sunset so I also took a pic. It wasn't until I got home and downloaded the photo to my PC that I realized the many discs in the photo. At first I thought maybe they were reflections of the lights, however I don't think this is probable.
