This direct route eliminates the need for transit through Taipei (the aerodrome that is better known as Taiwan Taoyuan International Airport (TPE)), reducing overall travel time and delivering greater convenience for passengers heading to Taiwan’s southern economic hub. Operators and analysts have interpreted this as a strategic move to capture both tourism and business traffic by improving accessibility.

Economic and Tourism Impact
Japan and Taiwan maintain strong cultural and commercial links, but Kaohsiung has traditionally lacked direct aerial links from Tokyo compared to Taipei. This service is expected to increase inbound tourism to southern Taiwan, especially from Japan’s Kanto region. According to Narita Airport:
“Kaohsiung is a port city located in the southern part of Taiwan, known for its attractive warm climate and open cityscape. In addition to the illuminated views along the Love River and the Dragon and Tiger Pagodas at Lotus Pond, the city offers many cultural and artistic attractions, such as the Pier-2 Art Center. Moreover, Kaohsiung is a culinary paradise where visitors can savor renowned seafood dishes at night markets, including Liouhe Night Market and Ruifeng Night Market.”
In addition to this, the opening of the route is also set to:
-
Stimulate outbound travel from Taiwan to Japan, including business travellers.
-
Enhance Kaohsiung’s profile on international travel itineraries.
-
Support local economies in both regions through increased passenger traffic.
Note that Jetstar Japan is a budget carrier
