Infrastructure minister Keiichi Ishii slammed Asahi Kasei Construction Materials Corp. on Friday following revelations of falsified construction records at three buildings in addition to a tilting condo in Yokohama and vowed to "investigate the issue thoroughly."
Ishii also hinted at expanding a ministry probe into the company's piling work, for which the data were faked, to projects undertaken by other firms.
"It is an extremely grave problem that different workers (from the Yokohama condo individual) were falsifying data in projects in different regions," Ishii told reporters. "We think the firm had problems with its project management system all across the organization. We plan to thoroughly investigate the company's piling work and its internal mechanism for checking projects, as well as its compliance with laws."
