Sompo Japan Insurance submits improvement plan after info leakage

It has apologized to customers and stakeholders.

Sompo Japan Insurance has submitted a business improvement plan to the local Financial Services Agency (FSA).

The FSA had earlier ordered the insurer to submit the plan on 24 March 2025, in relation to the leakage of customer information.

In a statement, Sompo Japan Insurance apologized for “any inconvenience and concern caused to our customers and all other stakeholders.”

“We formulated additional, more fundamental recurrence prevention measures than the business improvement plans that had been underway, to restore trust through re-emphasizing compliance with laws and regulations as well as customer protection,” Sompo Japan Insurance stated on 30 May 2025.
