Chief Cabinet Secretary Hirokazu Matsuno told reporters Japan signed deals with Pfizer and Moderna for a combined 170 million doses, which he said would be "enough to cover necessary doses".
Kishida was believed to have asked Burla to speed up the supply schedule. But the prime minister declined to give details of the vaccine supply and only said further details are still negotiated.
On Okinawa, health officials confirmed the Omicron infection in a Japanese employee, a man in his 50s, at the US Marine Corps Camp Hansen, which reported to the prefecture 70 new cases of coronavirus infection among its troops recently transferred from the US aboard a military aircraft. It brought the cluster at the camp to 99, Okinawan officials said.
Okinawa Governor Denny Tamaki told reporters on Friday that he has asked the US military to conduct a genome analysis on the samples to step up anti-virus measures and to strictly isolate the troops and keep them from leaving the camp.
Tokyo on Thursday confirmed its first case of the Omicron variant in a traveller from the United States who was isolating at home. Her friend whom she saw shortly after arrival has since tested positive for Covid-19 after attending a soccer game. His infection with the Omicron was confirmed on Friday.
The Health Ministry also said on Thursday that one of its quarantine officials tested positive for the Omicron variant. The new findings bring Japan's confirmed Omicron cases to 34.
Japan's Government says all Omicron cases so far have been detected by its border controls, but experts say it is only a matter of time before community transmission cases start surfacing.
Japan has stepped up border controls since the Omicron variant was first reported in South Africa and now bans entry to most foreign nationals. Japan has had about 1.73 million cases since the pandemic began, with about 18,400 deaths.
