Q4: How much of Minamata Bay was reclaimed?

A4: An area of 58 hectares was reclaimed.

Commentary:
Kumamoto Prefectural Government spent 14 years and 48.5 billion yen (Chisso Corp. bore 30.6 billion yen of it) to dredge up 1,510,000 m3 of the bottom sediment and carried out reclamation works in Minamata Bay.
As a result, 58 hectares of reclaimed land was created.
This is equivalent to 8 times the area of the Fukuoka Dome baseball stadium.
