These are all on my list of cool things I tell people about Japan. It really is a bunch of small stuff that I found great.
Another small one - most grocery stores have a packing area past payment and there's usually a little bottle with a light temporary glue next to the plastic bags. So the line moves faster and you never fumble opening the thin plastic bags
My pixel 7 Pro's vector motion sensor is broken. How the hell does that even happen? I've never even heard of it and there's like nothing online about it.
I can't do anything that requires tracking how the phone is moved- no compass calibration, no Map's guidance arrow, etc.
