Skymark Airlines is a Japanese low-cost carrier founded in 1996 and headquartered in Tokyo. It operates domestic routes across Japan and has grown to become one of the country's largest budget airlines, offering affordable fares primarily on high-demand trunk routes. The airline has faced significant financial turbulence over the years, including filing for bankruptcy protection in January 2015 before successfully restructuring and relisting on the Tokyo Stock Exchange in 2019. Integral Corporation became a major stakeholder during the restructuring process. Skymark focuses exclusively on the domestic Japanese market, connecting major cities such as Tokyo, Osaka, Sapporo, Fukuoka, Naha, and others. It is known for offering no-frills service at competitive prices while maintaining a reputation for punctuality.
