Tokyo to Narita by NEX

Hi gentlefolk of Japan guide, I`d like to ask a quick question that I`m hoping someone can help me with.

On the 144th of April I`ll be travelling to Tokyo, Now I know NEX does a one way deal to Tokyo from Narita Airport for 1500 yen one way, But I`ve noticed it looks like they dont do a return fare, can anyone advise me if they actually do a ticket from Tokyo station back to Narita for the NEX, or do we have to find an alternate way back?? I.e Sobu line etc??

Any help would be amazing as I`m quite nervous about this.

thanks in advance :)

You can of course take the N'EX from Tokyo to Narita, but you have to either buy a regular ticket at the full fare, or have a rail pass which covers it (the Kanto Area Pass, the JR East Pass, or the countrywide JR Pass). If you use a rail pass, remember that reservation is mandatory on the N'EX.
