Iriso Electronics has told the Kanto Local Finance Bureau that its internal controls over financial reporting were not effective as of 31 March 2026. Its president made that call in an internal control report filed on 30 September 2026, after restating years of accounts. The report lists six material weaknesses, and the first concerns the top of the company, not a single overseas ledger.
The filing adds to Tokyo Brief's earlier coverage of the committee's findings on payments. It describes how a narrow inquiry grew. The company set up an investigation committee of outside lawyers and accountants on 18 February 2026 after suspicions of improper payments tied to labour-dispute handling at an overseas subsidiary. Digital forensics then turned up events suggesting compliance problems in accounting and quality inspection, so on 27 April it appointed a third-party committee with a wider brief.
What the committee report found
The company received the third-party committee's report on 28 September. It says the report established improper spending at an overseas subsidiary, quality control and quality assurance problems at Iriso itself, the use of unconfirmed figures in provisional closings at overseas subsidiaries, and premature sales recognition at an overseas subsidiary. The company's own additional self-checks, together with the committee's work, also uncovered accounting errors in fixed-asset retirements and impairment, inventory valuation and consolidation.
Iriso restated the annual securities reports for the years ended March 2022 to March 2025, the second- and third-quarter reports for the year ended March 2024, and the half-year reports for the years ended March 2025 and March 2026.
Six weaknesses
The report says the control environment did not do enough to make compliance and reliable reporting a management priority, and that the mechanism for assessing executives' knowledge and securing integrity in their selection and evaluation was inadequate. It says the board and the audit and supervisory committee did not adequately oversee key decisions and internal-control problems. It also says conditions allowed decisions that put short-term results ahead of compliance with law, internal rules and customer commitments.
The other findings are narrower but wide in reach. Iriso's mechanism for assessing overseas compliance risk across the group was inadequate, and no specific assessment was carried out of bribery risk involving foreign public officials. Internal audit lacked staff and expertise for overseas subsidiaries, and the system for passing warning signs to management and the audit committee did not work adequately. Headquarters lacked an adequate system for understanding subsidiaries' controls, and reporting deadlines and escalation criteria were not clearly set. The global whistleblowing system existed, but its publicising and operation were inadequate. Subsidiaries' closing delays and local auditors' delays were not shared adequately with the company's own auditor. Year-end procedures, fixed-asset checks, inventory valuation and consolidation were inadequately designed or run, and at some overseas units the procedures for checking actual shipment dates against sales booked were not adequately established or operated.
The company says the weaknesses exist at Iriso and several overseas subsidiaries, affect multiple reporting items, and failed to prevent or promptly detect the premature revenue recognition and accounting errors. It says they came to light after the year-end and so could not be fixed by 31 March 2026. Corrections arising from them are reflected in the financial statements.
The repair plan
The planned measures include writing a compliance-first policy into its charter, adding integrity and risk-management criteria to executive selection and evaluation, setting a group-wide risk assessment covering bribery, reporting, quality and customs, and creating a whistleblowing channel to the audit committee. Iriso also says it will secure the specialist staff needed for internal audit, rebuild accounting procedures and checklists, and set up checks of shipment dates and inventory movements before sales are booked. The report gives no timetable for these steps.
The assessment covered 11 of the group's 13 companies. The two left out, it says, were excluded because sales and cost of sales of the group without them, including other subsidiaries, still exceed 95% of the consolidated totals. The report does not give the size of the restatements.
