Trip to Osaka/Nagoya/Kyoto

Hello,

We are a couple with 2 kids (5 and 3 yrs) and is planning to visit Japan in the upcoming Sakura season.

We need your advises on which regional pass we should buy for the following Iternary:

Option 1:
1/ March 25th: from Yao station (Osaka) to Nagoya, we expect arriving at noon the latest in order to take a bus to Nabana No Sato, then back to Nagoya in the evening.
2/ March 26th: Take a one day tour to shirakawa-go.
3/ March 27th: Visit Nagoya castle in the morning and take a train to Kyoto.
=> We have checked and supposedly that none of Passes are eligible and then we need to buy shinkansen ticket for this round trip (Osaka-Nagoya-Kyoto).

Option 2:
1/ March 25th: same as option 1.
2/ March 26th: from Nagoya to Takayama, then take a bus to Shirakawa-go and back to Takayama in the late afternoon.
3/ March 27th: Visit the old Takayama city and take a train to go back to Kyoto.
=> We are checking this JR regional pass (Takayama-Hokuriku Area Pass) and it would be supposedly included all the transportation cost from above trip. It is obviously cost effective than option 1. The possible cons of this option would be having longer travel time/transit between many JR lines.

Please correct me if I'm wrong, I will keep sharing my Itenary in Kyoto/Nara/Osaka/Kobe and look forward to your advise later on.

Regards,
David
