Though I think most of us promptly forgot that Pokemon Go even existed after the initial fervor died down, that’s clearly not the case in Japan.
This wasn’t the first time that I’ve seen a group of people (usually a dozen or so) congregating in one spot where there’s obviously a rare Pokemon or something (a gym? I don’t know, I played that game for like five minutes before I lost interest). But this was the most people I’ve seen by far.
I probably should have filmed a video, because I don’t think these pictures quite convey how many people were all clustered together in this one area playing Pokemon. It was actually pretty impressive.
