Scandinavian Airlines System has seen its business in Japan recover dramatically since the Great East Japan Earthquake and the upturn is continuing, according to an SAS executive.

"After the (March 11, 2011) quake, we have seen the market coming back. I am really impressed about the high potential of (the) Japanese market," said Eivind Roald, SAS executive vice president of sales and marketing.

2012 was the best year for the airline's business in Japan, Roald said, without elaborating.
