I'm travelling as follows:
1) Kansai Airport to Nara
= Kansai Airport - Ltd Exp Haruka 14 -Tennoji - JR Yamatoji Rapid Service - Nara

2)Nara to Kyoto
= Nara - JR Nara Line Rapid Service - Kyoto

3) Kyoto to Takayama

4) Takayama to Osaka

Which JR Pass is the best suitable and money-saving for me?
