thank you for the reply! i can't post the link as i do not have 5 posts yet but the video i mentioned shows a man getting off the plane and using a facial & passport scanner machine to avoid the long line shown in the background in order to get into the baggage claim area. i am now noticing it says priority so it may be for higher paying customers. i definitely plan to fill out all the forms on the visitjapan site that's what i did on my last visit in 2016 but these facial scanners are new to me and seem pretty helpful! thank you again
edit: here is the video link
the machine is at 9:40 in the video
