The nuclear crisis in Japan is expected to extend throughout this year, with British Airways confirming it has suspended flights to Tokyo’s Haneda Airport until further notice.

BA only began flying to Haneda in late February. However, the carrier will continue flying to Tokyo’s Narita Airport, to which it resumed direct services on April 2.

The Japan National Tourism Organisation in London reported visitors to Tokyo have fallen 75%, but said many of the country’s popular destinations were outside the area affected by the earthquake and tsunami on March 11.

A BA spokeswoman said the airline’s five-times a week service to Haneda had been suspended “due to reduced demand”. But she added: “We remain committed to the route.”

BA resumed flights to Japan soon after the disaster on March 11, but operated the services first via Hong Kong and then via Seoul to allow a crew change so UK-based crew could stay overnight outside the country.

Haneda is close to Tokyo’s business district and offers connections with domestic flights around Japan, whereas Narita is two hours from the city centre.
