Special annual passes won't get you into Tokyo's magical Disney resorts -- land or sea -- on certain busy periods starting with passes to be sold next month onwards, it has been learned.

Tokyo Disney Resort operator Oriental Land Co. announced on Feb. 15 that in order to counter congestion, the company will for the first time be designating days where annual passports for Tokyo Disneyland and Tokyo DisneySea will not be valid for park entry.

Passes to be sold on March 1 or later will be invalid for a total of 12 days this year, including Aug. 12-14, at the peak of the summer vacation, as well as Dec. 29 and 30 leading up to New Year's. In addition, there will also be cases on other days where passport-holders will be denied entry based on the number of visitors on that particular day to relieve congestion.

Oriental Land plans to announce any additional designated invalid days on the theme parks' official websites and other media at the beginning of every quarter in January, April, July and October, respectively.

To offset the move, the price of the annual passport for both Disneyland and DisneySea will be cut by 4,000 yen to 89,000 yen for adults and 56,000 yen for children (between the ages of 4 and 11). For the single-park annual passes, the price will be taken down 2,000 yen, to 61,000 yen for adults and 39,000 yen for children, along with other price changes.

The waiting time for attractions at Tokyo Disney Resort's land and sea parks has been growing longer, and a representative from Oriental explained, "We want to reduce congestion."
