So you stay in Japan between November 19-25, and between Nov 27 and Dec 3?

It’s difficult. If you want to use JR Pass during the entire stay, you have to buy 2 7-day passes or so

And you can’t go to Okinawa by train because Okinawa is a remote island. You need to think about it more.

You take your exchange order and your passport to the nearest JR office that does that exchange (it usually won’t be a regular ticket counter, but just watch the signs in the station or go to the ticket counter or information office and ask if you aren’t sure). There’s a small form you have to fill out, and I do believe they copy your passport, but so will all of your hotels. It’s just part of being a foreigner traveling in Japan. After they copy your passport and you turn in the form and exchange order, they should just give you your pass. When you go to buy a ticket, just present your pass and tell them where you’re going. You should also have your passport ready just in case they ask for it too. Then when you go through the gates to use any JR line train, you’ll want to go through the gate that does not have a turnstyle. That gate is usually right next to a manned office. At the office you’ll have to show your pass, your ticket, and sometimes you have to show your passport if you want to get through and board your train.

If you have JR Pass which is valid on the day you want to take a train, you can reserve a seat by showing the Pass.
