He guys, first up I’m the guy who found the image of him holding a beer.
It was barely simple I used the webpage https://pimeyes.com/en uploaded the image from the card, cropped it a little to hide the Japanese characters etc. The first two result where the same that I scanned. The third was the image holding the beer. I saw some resemblance, but didn’t think it would work. PimEys let’s you search for free but you have to pay for the full url. So I took the fraction of the url figured out the full one. Found the original image on the webpage. And then posted my findings to Reddit. I and also other users found new pictures of him the following days. On the 28th of December we found an image with him wearing a bib from a half marathon through the results I found the name and it was Satoshi.
