Tips for buying an iPhone at an Apple store in Kanto?

Never bought one before but I wanted to grab the regular iPhone 17 in black, carrier free.

Turns out they are sold out everywhere. I know they are popular but I didn't realise that even a while after release they would be hard to find. I could order online but I try to avoid having sensitive electronics shipped by underpaid and overworked delivery drivers who are in a rush.

To make matters worse, I feel like I am competing with tourists and resellers. That's the impression I got from a staff member which I guess makes sense with the weakening yen.

Anyone got any tips? How frequently are they restocked? If I wait early before store opening will I likely be able to get one or just setting myself up for disappointment? Is there any store in particular that seems to be better stocked in general?
