Around Obu train station, there are metal rails with sparrow sized metal birds perched on top. I’ve been to the station at least half a dozen times but have only noticed them this morning.
I didn’t see any info about the pieces or about the person(s) that made them. Most people around the station didn’t seem to pay them any mind as well.
However, I thought they were absolutely adorable and had to take a few pictures before heading to my appointment.
