Yeah i was over there last year and loved it.
Agree with everything the guys have said. Definitely see Miyajima if you can, it was probably my favourite place apart from Osaka.
Otherwise Nara is good for a bit of wildlife and culture. Not far from Kyoto or Osaka on the train.
How long are you going for? I was there for 2 weeks but wish it was longer. I barely scratched the surface.
