Our latest article about park ticket changes at Tokyo Disney Resort had incorrect information. It is our mission to give you the latest and accurate information about the resort. The error has since been corrected.
Tickets specified without a date (known as an open ticket) cannot be used on Japanese National Holidays or weekends. You must change the open ticket in advance to those dates (which can be done at the resort). Any tickets you buy in advance or at the ticket booths are all valid on these days.
Sorry for any inconvenience this may have caused. Thank you to Studio Lorien for the correction.
