This is a fun one dropping in.
Japan has opened up another airport – Ibaraki Airport – about 50 miles from Central Tokyo (so… no worse than Narita then)
Of course it’s a vastly filled service – with just one service a day schedule from it. The aim for it is to expand into a LCC Airport.
Airports always start off a bit small. Low landing fees and reduced costs might drive a few more carriers there.
