I live in Tokyo and wish I could see it through the eyes of someone new here again. I can see it in these videos, but when I walk through the city I'm too used to it and my brain drowns out all of these things.
So a technique I've found useful to solve this issue aside from hanging out with someone visiting is to dedicate 1 day to doing nothing but picking a place that you're very familiar with and intentionally thinking about whether you've been down that street or the next one, looking at places that I wouldn't usually look like at the corners of the roof of buildings and then just taking a moment to sit down and watch.
This has worked for me in each of the cities I've ever become too familiar with. You just tend to relax and get to where you want to go, there's no nervous energy of not knowing where you are or where you're going. Nowadays I tebd to just pop on my headphones and go to where I need and go back home again and not take in a thing unless I have a bit of a "reset"
I live here too and I get where you're coming from but I find that I can often remind myself of the things I like so much about Tokyo. Though I worry they are disappearing.
