Domestic budget airlines beat out foreign competitors in transporting passengers on routes to Japan last year.
Among 18 low-cost carriers flying to Japan, Korea's six budget carriers accounted for a combined 29 percent share of the market, according to OAG, an air travel-related service company. Japanese budget airlines came next with 22 percent.
"Korean airlines were able to top the market as they had a head start of four to five years before their Japanese counterparts," an industry insider said.
But in terms of market share of individual airline companies, Japan's Peach Aviation accounted for the largest share of the market, offering more than 200 million seats. Jeju Air came second with 1.97 million, running 11 routes from Incheon, Gimpo and Busan to six cities in Japan including Fukuoka, Nagoya and Osaka.
China's Spring Airlines came third, followed by Hong Kong Express Airways, Air Busan and Jin Air.
