No real confidence so they don't wander around and use their own brains. They just go to the top 10 spots chatGPT, tiktok, or some other list dictates.
It's like how people go to the Louvre and stand in line for 3 hours to look at one famous painting that they probably don't even really like all that much, and not see anything else in arguably the world's best gallery.
This is doubly true for a hot spot like Japan, because it's the current number one on the dumb lists.
