TOKYO -- Earthquake vibration absorbing system maker KYB Corp. on Oct. 19 released a list of 70 local or national government structures where its seismic dampers with falsified quality inspection data have been installed.

KSM President Shigeki Hirokado and Senior Managing Executive Officer Keisuke Saito made the announcement during a news conference at its headquarters in Tokyo.

"We are sorry about this inappropriate act," Hirokado stated at the outset of the news conference.

The 70 buildings include the Central Government Building No. 3 housing the Land, Infrastructure, Transport and Tourism Ministry, and the Finance Ministry's main building, both in Tokyo's Chiyoda Ward. They are among nearly 1,000 structures where KYB's problematic hydraulic seismic isolation or control dampers have been installed. Saito explained that the company publicly identified the 70 governmental facilities, which numerous people visit, after obtaining consent from the owners.

The questionable practice is suspected to have started in 2000 and continued because of a weak quality check system that has involved a total of only eight employees, company officials said earlier.

At least 70 percent of earthquake shock absorbers for buildings shipped by KYB and its subsidiary Kabaya System Machinery Co. (KSM) potentially do not meet quality standards set by the government or clients, according to the manufacturer.
