In April 1979, the first basic contract for the construction of Disneyland in Tokyo was signed.

Just one year later, construction of the park began and was covered by hundreds of media reporters as an indication of the high expectations for the park in the future.
Though successful in the building process, the final cost of Disneyland Tokyo almost doubled the estimated budget costing 180 billion yen rather than the projected 100 billion yen.
Despite this discrepancy, Disneyland Tokyo has been a constant source of pride since opening day over 30 years ago.

When Passes were renewed at the start of 2005, the Hong Kong Disneyland Resort was still under construction and it was noted on the Pass that it would not be valid for entry.
This was changed in 2006.
The two parks at the Tokyo Disney Resort - Tokyo Disneyland and Tokyo DisneySea - are not part of the allowance, as they are owned and operated by The Oriental Land Company under licenses from Disney.
On May 2, 2006, Disney honored the two billionth guest of a Disney park at Disneyland.
The guest received a modified version of the Golden Pass - this time, it entitled admission to the two theme parks at the Tokyo Disney Resort.
The Oriental Land Company allowed this because the two billion count included guests at Tokyo Disneyland and Tokyo DisneySea.
