Connection from Narita to Nagoya

Hi,
I am travelling from India to Japan. Arriving to Narita at 16:00hrs and i would like to travel to Nagoya by Train, i need advice as how to get connected by train to nagoya from narita and what times the train are available.

This thread from a few days ago is almost perfectly applicable to your situation - just replace "Kyoto" with "Nagoya" and you're set.

The limiting factor will be the Narita Express from the airport, which leaves twice an hour. Connecting trains to Nagoya leave very frequently, no fewer than six an hour.

If you are on the 16:45 train leaving Narita, you should easily be able to connect to the Nozomi 139 in either Tokyo or Shinagawa, reaching Nagoya at 19:42.
