The president of Huser Ltd. admitted Monday that the condominium developer concluded sales contracts and handed over units even after being told in late October that the quake-resistance data for its buildings had been falsified, leaving their structural integrity in doubt.

Although he confirmed reports that the firm was aware of the scam, Huser President Susumu Ojima, 52, claimed he had not recognized the significance of the data fabrication at the time.

Other Huser officials also said the firm had not realized at the time the condo complexes it developed had substandard quake resistance.

Huser may have violated the Building Lots and Buildings Transaction Business Law by concluding the sales contracts.

On the afternoon of Oct. 25, disgraced architect Hidetsugu Aneha told a Huser executive visiting the office of eHomes Inc., a government-designated building inspection agency, that he had reduced the quake-resistance strength in calculating the data for condominium complexes developed by Huser, the company officials said.

The executive, who was not identified, returned to Huser's head office in Tokyo with Aneha, where the architect gave a similar explanation to Ojima, the officials said.

Later that day, the executive accompanied Aneha to his office in Ichikawa, Chiba Prefecture, and was handed the names of seven or eight condominium high-rises developed by Huser for which Aneha had fabricated quake-resistance data.

The complexes included Grand Stage Funabashi Kaijin in Funabashi, Chiba Prefecture, and Grand Stage Fujisawa in Fujisawa, Kanagawa Prefecture.

Huser concluded a sales contract for a unit at Grand Stage Fujisawa on Oct. 26 and delivered 17 units on Oct. 28.

Ojima instructed his employees on the evening of Oct. 27 to halt all condominium sales, but a contract for a unit at Grand Stage Funabashi Kaijin was concluded Oct. 29 because an initial payment had already been made, according to the officials of Huser.
