So far, we can get to 35 destinations in China directly from Kansai International Airport. It's more than double of domestic destinations, and of course, it's the largest number of China's destinations in Japan's airports.
I guess the reason why so many flights are launched is a balance between the varieties of tourist attractions around Osaka and the distance between Osaka and China's cities.
