if you arrive in NRT and depart from NRT.

You have the following costs with a normal tix.

NRT -TYO Narita Express 3000 YEN
TYO - NGO Shinkansen 10780 Yen
NGI - TYO Shinkanse 10780 YEN
TYO - NRT Narita Express 3000 Yen

Only to go from airport to nagoya station will cost you 27650.

As you can use the railpass for every JR bus and every JR train. it is a nice value .

i think the railpass was around 28300 yen a week?

so if you just add some local trains. and i am sure you will. it will be cheaper.

if your outbound is from kix etc. than it does not pay.
