I'm a little confused about the options from getting from Kyoto to Kansai.
What I'm not clear about is:
-there appear to be two rail companies operating into Kansai Station. Which one should we be looking at?
-if the right railway company is JR, would it be useful to purchase a JR pass for use on this leg, as well as the Tokyo-Kyoto leg we'll be doing about 10 days earlier
-does the trip from Kyoto to Kansai require a change of trains?
