Of the sum, about 1.98 million yen was for one-way tickets for the three from the United Arab Emirates to Japan, and return tickets for two relatives and a lawyer, the official at the International Hospitality and Conference Service Association said.

In addition to these costs, the ministry is considering asking the three to pay part of the cost of chartering the plane they took from Baghdad to the UAE capital Dubai, ministry officials said.
Their relatives already paid medical and hotel costs for the three when they visited them in Dubai, they said.
No word on when the bill for the actual release will be coming.
