Hello I am travelling with my spouse on March 18-27. 6 days in Tokyo and 5 days in Osaka. Some were saying that it is not advisable to get a JRail Pass as it will not be useful for public transportation as it is a private one. I would like to know if we can use this when we travel anywhere in Tokyo and Osaka. Like going to special attractions and Theme parks like Disneyland and Universal Studios.
Thank you!
