Recently, some of my friends discussed about Chubu International Airport, or Central Japan International Airport. The conjunction city was going to change its name to "South Centrair city" due to the fact that the pet name of Chubu Airport is "Centrair", which is a synthesised word of "central Japan" and "airport." (Later, this naming was rejected by citizens of the city.)

To my surprise, though my friends knew the "Centrair," they did not recognise once-called New Tokyo International Airport had become Narita Airport last April....orz

I should say that public relations department of Narita Airport Authority has not made enough efforts to advertise its name.

Wmn, looking the positions of these two airports, I wonder if the Chubu "Centrair" Airport is "centre" of Japan.

Postscript: Oops, I borrowed this map frim CIA site... there written "Occupied by the Soviet Union in 1945, administrated by RUSSIA, claimed by JAPAN."
