Using N'ex Round Trip Ticket

[Cindy K]

Hello, I will be traveling to Tokyo in a few months. I plan to get a N'ex round trip ticket. My journey is basically Narita Airport > Tokyo > Yokohama > Tokyo > Narita Airport within a 7 day period. I would like to clarify on a few areas:

1) I read that using the N'ex Round trip ticket, I am allowed to transfer to other JR trains within the designated Tokyo train area. What does "once exiting a gate, ticket cannot be used for re-entry"?. Since the ticket is valid for 14 days, am I not entitled to ride unlimited trains within the designated Tokyo train area? 

2) Since I will be purchasing a N'ex return ticket, will I be using the same physical ticket for the whole 14 days duration? If not, does it mean that I will be given a separate ticket for my return trip to Narita airport at time of purchase? 

3) I may choose to purchase a Suica for areas not covered by the designated Tokyo train area (e.g. Visiting Sanrio Puroland). Thereafter, can I jump back on using the N'ex return ticket once I'm ready to head to Yokohama on Day 4 or Day 5? I'm confused hence Question 1) above

4) I have a 9.30am flight to catch at Narita Airport on my last day in Tokyo. Which station should I go to, to board the N'ex train to ensure I get to the airport by 7.30am? I understand operational hours differ by stations. 

Thanking you in advance. Really need to know how this ticket would work for me.

Hello there,

1) & 3) The N'EX TOKYO Round Trip Ticket is a return ticket between Narita Airport Terminals 1 and 2·3, and major stations in the Tokyo metropolitan area. What you will get are 2 trips in ordinary car reserved seats on the Narita Express. I would recommend you read this: https://www.jreast.co.jp/e/pass/nex_round.html

2) You will get 2 separate tickets.

4) You can check the Narita Express' timetable here: http://www.eki-net.com/pc/jreast-shinkansen-reservation/english/wb/common/timetable/e_nex_d/index.html

I hope that helps.

Best wishes,
