I prefer not to take a bus if I can help it, since I tend to get carsick if I'm not in the very front. So I've been leery of flying in to HIJ, since it looks like a bus is the only option to get to Hiroshima. But now that I study the Japan Rail search site, it looks like from either ITM or HIJ one needs to take a bus to get to the train station. Or maybe a cab, I suppose, but how much would that cost?
