[Teris]

My wife and I will be spending most of our time during our 10 day stay in Tokyo and Kyoto, but we plan on doing some day trips to Nikko, Nara, Hiroshima. I was planning to get a Suica card for subways in Tokyo (and we already have JR passes), but I'm finding different information on whether it will work in Kyoto, Nikko, Nara and Hiroshima. Can someone please advise what would be the most convenient way to get around these cities? Thanks!
