Hi. My family and I plan to go to Tokyo for a few days, leave for Osaka via shinkansen on the 6th day, and depart from Osaka back to our country on the 9th day. The 14-day JR Pass seems inadvisable. Would it be advisable to get a 7-day JR Pass? Aside from the shinkansen, we plan to use the JR Pass to go to Rinku Town on the 8th day and Kansai airport on the last day.
Also, can we use the JR Pass to go to Osaka Aquarium Kaiyukan? Thank you.
