Hello there,
We are a family of 4, (2 children aged 6 and 7 yrs), travelling Osaka (2nights), Kyoto (3 nights), Takayama (2 nights), Hakone (3 nights), Tokyo (4 nights) in January. YAY, I can't wait!!!
I am trying to look up costs for our rail fares between these destinations (using Hyperdia and also the Japan Rail website). I am trying to work out the the most economical/cheapest

way to purchase the fares.
I have become confused when searching the journey Kyoto to Takayama (by train via Nagoya seems to be the best way), and then also the journey from Takayama to Hakone (Odawara), which also seems to need to go via Nagoya.
The fares I have found are: Kyoto to Takayama - about Y8970 per adult, and then Takayama to Hakone Y11950 each (with the children being a bit less).
This seems very high and I'm not sure if I'm looking it up correctly, or if maybe we should purchase some return tickets (eg: the Nagoya to Taka return) and if this may work out cheaper. But can the return ticket be used after a 3 day break or does it have to be used the same day? Where do I find return prices?
I have also been told previously on another forum that the JR pass will not work out cheaper for us because we are flying into Osaka, doing the journey above and then flying out of Tokyo, so there is no return journey. Do you think this is correct?
Any advice or websites you can offer would be very much appreciated.
Thank you!
Tiff
