Osaka's tourism bureau began surveying foreign travelers Monday about their level of satisfaction before they leave Kansai International Airport in a bid to increase the number of foreign tourists to the prefecture.

At the departure lobby of the airport, four female researchers asked foreigners about the length of their stays and how much they spent on sightseeing in English and other languages, and input the data into tablet computers.

The bureau will analyze the data to estimate tourism revenues and set business targets. Kunio Kano, head of the tourism bureau, said the survey is necessary to see what impression foreign travelers have of Osaka.

The bureau was opened by the prefectural and city governments of Osaka and local business groups on April 1.
