It makes sense to fly to Nagoya if you are transferring from another plane. And they could service it with puddle jumpers. It is too bad that Haneda or Narita aren't serviced by Shinkansen stations themselves, then you would just take the train.

It's a pretty quick 20 minute ride on a local train from Haneda to Shinagawa station. Narita is a bit tougher, yes.
