Those FPV walks through various Japanese area videos, from channels like @4KJAPAN or @VIRTUALJAPAN, are strange because they actually make me feel like I've been there.
Like I have a memory of walking through Japan and it can be a bit jarring when I realize it was just a video I watched.
It feels as real to me as actual cities I've walked through. Like I remember my "walks" through various Japanese areas more vividly than my walks through Florence, Italy, or Brussels, Belgium, but I've actually been to the latter two.
