well gals...it is because Fukuoka is situated in the island of Kyushu...
Fukuoka is the city within the island of Kyushu
check it out

Their site of filming - The Huis Ten Bosch theme park is located in Nagasaki, Kyushu...

So my guess is they went first to Fukuoka, Kyushu (as their point of entry from Taiwan)
before going to Huis Ten Bosch in Nagasaki, Kyushu...
