Zentoshin Co., an Osaka-based credit card payment processor, filed for voluntary bankruptcy on July 6, with the Osaka District Court approving proceedings the same day. The company reported liabilities totaling approximately ¥125.9 billion, roughly $710 million to $778 million depending on the exchange rate. That makes it Japan’s largest corporate bankruptcy of 2026, and creditors are now scrambling to recover what they can.

It served around 200,000 merchants, predominantly small restaurants and retailers, offering early-payment services on credit card sales — advancing funds so small operators could pay suppliers, staff, and rent without waiting for credit card settlements.

What brought Zentoshin down

The collapse traces back to two compounding problems. First, the company never fully recovered from the revenue pressure caused by the COVID-19 pandemic. Then, in January 2024, employees were arrested in connection with fraudulent merchant contracts. The misconduct fundamentally damaged Zentoshin’s relationships with its creditors, the very institutions it needed to refinance its way through the revenue drought. When the banks stopped trusting the company’s books, the refinancing window slammed shut.

Regional banks left holding the bag

The fallout is already rippling through Japan’s regional banking sector, where several institutions had significant exposure to Zentoshin.

Towa Bank has reported roughly ¥8 billion in exposure. Taiko Bank faces about ¥1.5 billion in risk. Bank of Kochi sits at approximately ¥1.2 billion, and Shimane Bank has around ¥800 million on the line.

Stock prices for several of these banks have already started reflecting the damage, with institutions announcing writedowns or loan-loss provisions.

200,000 merchants in limbo

Zentoshin’s early-payment service was a cash-flow lifeline for small businesses. With that service suddenly gone, roughly 200,000 merchants now face potential cash-flow disruptions. The concern among Japanese financial regulators and industry observers is that Zentoshin’s collapse could trigger a wave of secondary bankruptcies among small enterprises that depended on its services.
