Hi. I'm travelling with my wife and 2 kids (6 and 9 yrs). We're going to Tokyo but would like to slot in USJ and Mt Fuji. We have 6 days full days. Can someone advice which travel pass to get that will allow us some savings? Also whether it's advisable to put up a night in Osaka and Fuji or is a day trip sufficient? We do not want to rush it.
