Japan Air System (JAS), later known as Japan Airlines Domestic from 2004, was the smallest of the big three Japanese airlines. In contrast to the other two, JAL and ANA, JAS' international route network was very small, but its domestic network incorporated many smaller airports that were not served by the two larger airlines. As an independent company, it was last headquartered in the JAS M1 Building at Haneda Airport in Ōta, Tokyo. It has since merged with Japan Airlines.
