Owners of condominium complexes developed by Huser Ltd. with fabricated quake-resistance data called on the government at a Diet committee session Thursday to increase support for rebuilding the defective structures.

"We want (the government) to extend support that would remove residents' anxieties," Katsutoshi Shimizu said during a session of the Committee of Land, Infrastructure and Transport of the House of Councilors.

Shimizu owns a unit in Grand Stage Sumiyoshi in Tokyo's Koto Ward.
