Flights to Japan’s main international airports Tokyo Haneda and Narita are returning to normal, following Friday’s devastating tsunami.
While flights are able to operate from the airports, public transport to the city centre is intermittent due to power cuts.
The Foreign and Commonwealth Office is currently advising against all non-essential travel to Tokyo, due to the damage caused by the quake, which measured 8.9 on the richter scale.
The Japanese Meteorological Association has warned that there is a 70% chance of a magnitude 7.0 or greater earthquake in the same region within the next two days, which could trigger another tsunami.
The Japanese authorities are warning residents to stay away from low-lying coastal areas.
National carrier Japan Airlines (JAL) cancelled more than 300 international and domestic flights on Friday and Saturday (March 11 and 12), while other services were delayed.
On Sunday (March 13), however, the airline was able to operate the majority of its flights, cancelling just 24 domestic flights and two international flights.
British Airways cancelled flights on Saturday, but is now operating its services as normal.
Finnair's flights to Tokyo, Nagoya and Osaka are now operating normally, however the airline is offering passengers with tickets booked between now and March 18 the opportunity to change their flights free of charge.
Many passengers due to travel from the UK have cancelled their Japan flights for the coming days, according to global distribution system operator Sabre.
Martin Cowley, Sabre Travel Network’s senior vice president for Europe the Middle East and Africa, said: “As expected, we have seen a spike in booking cancellations on flights from London to Japan.
"We are now working hard with our agency partners to use technology and collective experience to support the reaccommodation of all travellers.”
