Checking itinerary and other questions

Hi there-

We are visiting Japan 2/12 - 2/23 and want to check if the 14 day JR pass makes sense for us vs point to point tickets.
We will be in Tokyo 2/12, departing for Kyoto 2/15, departing Kyoto for Kochi 2/17 -- also planning a day trip to Hiroshima while in Kochi. Returning to Tokyo 2/22. We will be travelling with our daughter who is on a year assignment teaching English in Japan -- it doesn't look like she will be able to use this pass since she is not technically a "temporary visitor", is that correct? If not, would she be able to purchase tickets for the same trains we would utilize?

Any feedback you have is appreciated, and also any suggestions on things we should see given the area we will be travelling. Thanks!
