South Korea and Japan began tightening border controls on travelers from each other over fears of the novel coronavirus on this Monday.
The visa-waiver programs for both countries have been suspended and previously issued visas are no longer valid.
Those who enter Japan will have to self-quarantine at home or at their accommodation for 14 days, and are not permitted from using public transport when leaving the airport.
All flights between South Korea and Japan were cancelled today, except for those heading to Japan's Narita and Kansai airports from South Korea's Incheon International.
There were only 11 passengers departing from South Korea to Japan on Monday, and just 3 of those were South Korean nationals.
