The Japanese government have provided local governments with lists of uninfected passengers from the Diamond Princess cruise ship, quarantined for the new coronavirus at the port of Yokohama in Kanagawa Prefecture, south of Tokyo, informed sources said Saturday.

The lists, which contained information about people who disembarked from the ship earlier this week after having tested negative for the virus, are very important for local governments in their efforts to monitor such passengers' health conditions, sources familiar with the situation said.

As local governments initially had no access to such information, even after uninfected passengers started leaving the ship on Wednesday, some governors had expressed their frustration over such situation.

"We finally received what we had been seeking," said an official of the prefectural government of Tottori, central Japan.

Information about disembarked passengers who are residents of Tottori was provided to the prefectural government on Friday afternoon via an email by the Yokohama Quarantine Station in Kanagawa.

The Tottori government received information such as names of the passengers, their date of birth, sex and phone numbers, as well as ways to monitor their health condition and report monitoring progress to the central government.

But the list only had information about the passengers who left the ship on Wednesday. It remains unknown when information on passengers who got off the ship on Thursday and Friday will become available, the sources said.

The Tottori government official said the prefecture, based on the list, will make contact with the disembarked passengers through regional public health centers and give them health counseling and necessary supplies, such as face masks and disinfectants.

The local governments that received information about disembarked passengers included Osaka Prefecture in western Japan.
