We were in Nara this summer. I use a powerchair. We stayed in Osaka and took the train to get to Nara, all accessible as someone mentioned. Then we took the bus to the park (buses were accessible too). The park is accessible, it is big! After the Deer Park we rolled/walked to the Todai-Ji temple. That temple is very unique and fully accessible. There is a ramp at the entrance.  Enjoy your trip, Japan is an amazing country!
