Update #1: it seems that the article was talking about March 14th (Monday) and not about a timeframe of 14 days. The initial Google translation was:
"Miyagi Prefecture factory to produce high-end digital SLR cameras for professionals, announced that it is virtually impossible to resume operations in 14 days".
Update #2: here is a better translation of the text:
"Nikon announced on 13th that they cannot re-start operation of high-end digital SLR camera actually from 14th. The building was not damaged by tsunami but they announced it is not clear when the plant could be re-started because they cannot expect power and material supply at present. They are checking production equipment now."
The Japanese site Asahi reports that Nikon's plants in Miyagi Prefecture (where Sendai is located) are virtually impossible to resume operations in 14 days. The buildings were damaged but still standing. The Sendai factory produces high-end and pro level Nikon SLR cameras.
