Me and my boyfriend are going to Japan for 3 weeks in August and I don't really know how to start planning the trip. We would like to travel around and see not just the cities but also the nature a bit. Is it worth buying the 14 days Rail Pass? What would be your recommendations - how many days should we spend in Tokyo, Kyoto etc. Is it worth going hiking in the mountains? Is there anything we should do or avoid in August? Thanks for any help!
