The Japanese division of Triumph International is recalling more than 20,000 bras after receiving complaints that underwires suddenly poked out, sometimes while consumers were wearing them, Reuters reported.
The company, which has made a name for itself with concept lingerie such as a solar-powered bra and an "Abenomics" bra, said it took the move due to fears of female clients being injured.
"We are sorry for the bother, but we ask customers to stop using the bras immediately," the company said in a statement, adding that it deeply apologised and would take steps to prevent a recurrence.
Although there have been no complaints of injuries from the faulty design in the bras yet, the lingerie company said "it would be terrible if it happened and somebody’s skin was scratched."
The recall applies to roughly 22,000 bras ranging in cost from 5,600 to 6,200 yen (£30 to £33) and sold only in Japan, a company spokeswoman told Reuters.
