I went from NRT TO NGO. Just go to the JR desk and they will be able to help. Key words: narita express, shinagawa station (changeover point from press to,shinkashen train), nagoya. Make sure the ticket starts in Narita so you can take the hotel shuttle to Narita Station. The guy understood English well enough that he gave me 2 different prices based on class. Regular class or Green car (business class) I got mine in the airport terminal. I bought tickets for 3 of us in about 5 minutes.
