The refurbished South Wing at Narita International Airport's Terminal 1 opened Friday amid high hopes from the airport's operator and All Nippon Airways Co., the terminal's main tenant, that the improvements will attract more passengers.

With the completion of the decade-long renovation and expansion, Narita International Airport Corp. (NAA) has arranged the airlines that use the terminal according to their alliance groupings to make connections easier.

"(Narita) will be the world's first airport to allocate each of the three largest airline coalitions (Star Alliance, oneworld and Sky Team) to different terminals," NAA President Masahiko Kurono said.
