There was a guy a long time ago, who did YT videos of the tech markets in Tokyo and it was really surprising some of the best places to get parts for smartphones or robots were completely non-descript buildings in the heart of the city. He specifically went to places that most people wouldn't know about unless you really had great local information.

If someone were to do what you're saying, it would be a huge win for people visiting and being able to find these places. I would love to see this.

You reminded me of Strange Parts who was in China, able to pick up random stuff like an iPhone motherboard from a lady selling it on the street.

Do you think those videos of tech markets in Tokyo are still online? I would enjoy seeing them.
