Tbh security in Japan has been pretty similar to TSA PreCheck. Shoes on (except in some cases closed-toes), laptops stay in your bag. The staff at HND and NRT has been very friendly, pretty much like DFW and LAX TSA in my experience. SFO was the rudest; okay, I know I made a noobie mistake and I should have kept my TSA PreCheck card instead of leaving it in the bin (it was my second flight ever as a TSA PreCheck holder), but there's no need to be sarcastic and rude, oh officer....
But it's ok. Only adds 2 minutes of me taking my laptop and shoes off and going to the enhanced X-Ray machine.
I'm not sure about TPE, whether it's similar to TSA PreCheck and Japan, or whether you do need to take your laptop out and shoes off.
