Hi all!
I have had a look at Hyperdia and it seems like its worth it, but just wanted to check with some real people if a JR pass is my best bet - I'm staying in Osaka for 4 nights and want to do some day trips to Nara, Kyoto etc. (I also want to get to Hiroshima too), and then I was planning on travelling to Tokyo by train too, where I'm staying for 2 nights.
Thank you!
