Corporate bankruptcies in Japan rose 12.4 percent in May from the previous year to 1,528 cases, marking the seventh consecutive monthly rise, a private credit research agency said Wednesday.

The figure exceeded 1,500 for the third straight month, Teikoku Databank said in a report covering failures involving liabilities equal to or greater than 10 million yen.

Liabilities left behind by the companies that failed in May totaled 1.67 trillion yen, up 3.9 percent from a year earlier, after declining for two straight months year-on-year.
