N'EX Tokyo Round Trip Ticket

Hi, I just wanted to check my understanding and confirm the following -

I will arrive at Narita airport buying a N'EX TOKYO Round Trip Ticket (4000yen) and reserving the return ticket and seat. Then I can catch N'EX to go in to shinjuku and check in my hotel.

On my return date within 7 days, I will check out my hotel from Ueno. I will need to buy a ticket to catch another subway to TOKYO station to board N'EX to go to Narita airport.

Please tell me if this is correct procedure. Thanks.

You are correct. The NEX goes from Narita Airport to Shinjuku for your arrival. When departing you'll need to catch the Yamanote line from Ueno to Tokyo Station to get on the NEX back to Narita Airport.

No need by JR Yamanote line(outer loop) or JR Keihin-Tohoku line
take JR Ueno-Tokyo line from JR Ueno stn to JR Tokyo faster.
(non stop/next stop is JR Tokyo)

And by return ticket valid from JR Ueno to JR Tokyo.
So no need to pay to Tokyo stn fare.

In JR Tokyo NEX stop Sobu Line(Underground Platform) be carefull.

By subway is not JR line need subway fare.

Thanks for the replies.

I just found out our hotel is located in Higashi Shinjuku (Hotel Sunroute Higashi Shinjuku), not Shinjuku. So my question is, can I transfer via 大江戶線 from Shinjuku to Higashi Shinjuku using N'EX Tokyo Round Trip Ticket? or I need to exit and buy another ticket for one stop?

Thanks!!

No, the subways are a different system than JR. You could either transfer to the Oedo line at Shinjuku, walk or take a taxi to your hotel. I'd probably just take a taxi as it easier and potentially cheaper than taking the subway.

We have four people with four pieces of luggage. Are you sure it would be cheaper to catch a taxi than catching a subway? thanks!
