I might stay in Tokyo one less day and add that day to the Kyoto stay, but otherwise it doesn't look bad.

I am assuming that you will base your Kinki visit out of ONE of those cities - Kyoto or Osaka rather than moving from Tokyo to Kyoto to Nara to Osaka, then back to NRT. Kyoto, Nara and Osaka are all just a short train ride from each other and easily visited from a central base. I'd find a nice place to stay in either Kyoto (my preference) or Osaka and just do day trips to the other places. That way, you only have to hassle with luggage and check-in/out once and have the whole day to see the sites in each location.

For this itinerary, it seems that the Japan Rail Pass would be good value for you. Purchasing seperately for the trip from Tokyo to Kyoto plus the trip back from Osaka or Kyoto to Tokyo, plus the Narita Express from Tokyo Station to NRT plus the trips from Kyoto to/from Nara and Osaka all add up to more than the cost of the Pass. You would pay out-of-pocket for the initial ride into Tokyo from NRT upon arrival and activate your pass to start on the 2nd and be valid through your last train trips on the 8th.

Sounds like a good trip. Have fun!
