Osaka to Tokyo

EmmaKate

Hi,

I am just wondering if it is worth getting a JR pass for the following.
September 24 - Osaka - Nagoya
September 25 - Nagoya - Tokyo
- Tokyo to Narita Airport.

We are on a tour for the two weeks prior to the 24th.
It's not much travel so I am hesitant to get a JR Pass, just looking for some insight.

Thanks
