Takata Corp. suppliers and employees expressed concerns on Monday following the embattled company's decision to file for bankruptcy protection amid a global recall of its defective air bag inflators.

"We just received delivery orders two days ago, but I'm worried if we will ever get paid," said an employee at a car component company in Takashima, Shiga Prefecture. "Even if the amount is small, it will hurt smaller firms like us."

According to credit research agency Tokyo Shoko Research Ltd., around 40 percent of Takata's more than 130 tier 1 suppliers are based in the Kinki region, mainly in Shiga.
