In the report on nationwide prefecture and municipality land areas for 2011 announced on January 31 by the Geospatial Information Authority of Japan (GSI), Tokyo's Ohta Ward experienced the largest increase.

The results, compiled according to the GSI's measurement of land areas as of October 1, 2011, show that Ohta Ward expanded by 0.96 square kilometers due to the construction of Runway D in the waters around Haneda Airport, representing the largest expansion among Japan's municipalities. Ohta Ward stands out among the other municipalities in the Kanto region, as the additional land is equivalent to 20 or so Tokyo Domes (home of the Yomiuri Giants, Japan's most popular baseball club).

The initial calculations do not include movement in the Earth's crust or other such effects from the Great East Japan Earthquake that occurred on March 11 of last year. To account for them, a new set of high-precision land area observations using digital mapping data is needed. This data is now being gathered across Japan and the GSI is considering how to apply it.
