Which JR PASS will buy? (You can paste the PASS url here.)
BC can not answer Q3 unless you tell me the name of the PASS.
Q1 is "Y", Q2 is "N". (explain later)
When is the time to depart NRT?
However, you can check the fare without discount here.http://www.hyperdia.com/en/
Click "More options" first, then uncheck "Private Railway".
NRT has 3 terminal buildings(T1 to T3) but 2 rail stations,
but you can search not only the station name but also the terminal name.https://www.narita-airport.jp/en/sitemap
The answer of Q2 is here, see the rail map.https://www.narita-airport.jp/en/access/train/
And it is worthless to take Shinkansen btw Tokyo and Ueno station.
The reason is that it takes time to transfer at Tokyo station
and Shinkansen platform of Ueno is deep underground so it also takes time to leave the station.
If not in weekdays morning and evening rush hour,
take a regular commuter train (no reservation seat) of JR enough.
But again, can not check about you have to it or not without telling the name of PASS.
If "JR TOKYO Wide Pass", only "Rinkai line" covered, so "all No" is not correct.http://www.jreast.co.jp/e/tokyowidepass/index.html
Google maps can not select only "JR" line or not.
