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.

Concept and construction.
The concept of an amusement parK in began with the 300th year anniversary of the recorded founding of Kolkata (then Calcutta).
While planning was under way for the tricentennial celebrations by the ruling State Government, Rajive Kaul, currently Chairman of Nicco Group, was in the US on a family holiday to Disneyland.
As per the story, when Kaul returned, there was an inquiry as to why he left for America when he was very much required back home for the planning process.
Supposedly, Rajive replied, "I'd gone to see if I could create a Disneyland here."
What at first seemed to be just an excuse to justify his absence actually materialised to a joint venture with the West Bengal government.
