Location

The city Kitakyushu is located in the north part of the Kyushu Island. From abroad you can fly to Fukuoka (Fukuoka Airport) or Kitakyushu (Kitakyushu Airport) via Tokyo (Narita Airport or Haneda Airport) or Osaka (Kansai Airport) or Nagoya (Chubu Airport). Also there are direct flights to Fukuoka from some countries mainly in Asia. The Kitakyushu Airport is the most convenient to get to KIT but there are flights only from Tokyo (Haneda Airport). From Fukuoka Airport it is easy to get to KIT by train or by bus. You can find some more information on the websites below.
