A Yokohama integrated resort (IR) looks like it’s going to carry a pretty steep price tag. A survey of potential operators reveals that it could cost as much as $12 billion to build, and six of those firms are willing to pay the price.

GGRAsia reports this information came from a request for information (RFI) by Yokohama city. Although the information was compiled in September 2018, it was kept concealed until May 27, with some of the information still kept private.

Of the responses that they got, operators suggested they would be willing to build a resort for as little as 620 billion yen ($5.66 billion), or as much as 1.3 trillion yen ($11.9 billion). Thus the city thinks they can get a cool $12 billion in investment, rounding up of course.

They also determined they could get between $3.2 billion to 8 billion in annual revenue from a resort. Annual earnings before interest, taxation, depreciation and amortization (EBITDA) is expected to come in at around $730 million to $1.9 billion.
