Corporate bankruptcies in Japan between January and November of this year climbed 17.7 percent from the same period last year. A total of 9,053 companies went under in the period.

Credit researcher Teikoku Databank says in November alone 834 companies filed for bankruptcy with debts of at least 10 million yen, about 66,000 dollars. That's up nearly 8 percent on year.

The survey shows that in the full 11 months 877 businesses failed after production costs outpaced market prices. Another 311 businesses attributed bankruptcy to shortages of workers. Both figures increased from a year ago.

The credit researcher says businesses continue to struggle with inflation and finding staff. It adds that the number of bankruptcies for the entire year could top 10,000 for the first time since 2013.
