Aichi ranked fourth nationwide in new factory construction in 2012 with 51 new locations designated for plants, a report compiled by the Ministry of Economy, Trade and Industry said.

Although the prefecture's rank slid from second last year, new properties rose by eight, with the aerospace and automobile industries leading the way with 11 new facilities, or 20 percent of the total. The food industry was close behind with eight.

"Business expansion is progressing smoothly, which can be credited to the success of the prefecture's subsidy program for new factory construction," said an official from Aichi's industry and labor department.
