Increased Need for High Quality Internal Audit Services in Japan

1.  Growing number of fraud cases in overseas subsidiaries

Statistically, the risk of fraud is higher at entities further removed from headquarters. Not all fraud starts with malicious intent. But even with the aid of modern technology, maintaining effective controls over a geographically remote location remains a challenge. Recruiting good internal auditors in Japan is often difficult, and nurturing local talent that can provide the much-needed link between headquarters and overseas subsidiaries requires time, effort and money.

Overreliance on external auditors can also make an organization vulnerable. External auditors determine the depth of audit based on the importance of the entity in the group, often giving smaller subsidiaries low priority. This is the cause of much frustration among shareholders and clients, who depend on external audit reports to validate their trust in the organization. Enhancing the internal control function is an effective solution to address a gap in expectations that is difficult for external audit firms to resolve themselves.

2.   Mounting pressure for better corporate governance in Japan

Once exposed, dealing with fraud is extremely difficult, especially given increased public scrutiny in recent years. Damaged trust, loss of face, plummeting shares, financial fines, independent investigation committees, and perhaps the most severe consequence of all – deeply demoralized loyal employees who took pride in their work and identified themselves with the corporate brand.
To eradicate fraudulent behavior, an organization must question its processes and remedy cultural traits that may breed such psychology. It is a long-term, strenuous process only possible with expert insight and a team of talented, dedicated internal auditors committed to the task.  

3.   The unique challenge of auditing “internally”

Lifetime employment is much the norm in Japan, and internal audit staff are often introduced to the task as the result of an interdepartmental job rotation. Although they have the advantage of understanding the workings of the company, not all employees are the right fit for the role, and an internal auditor may choose not to speak out against the organization for fear of jeopardizing a lifelong career.
In addition to the dilemma of securing quality talent, corporate governance is a relatively new concept in Japan and the departments being audited are not always receptive, creating further challenges for internal audit staff.

4.   Rise in M&A activity

ith the Japanese economy in slow decline, companies are increasingly turning to M&A as a strategy to gain market share and ensure business succession. However, mergers must be managed with care, especially with regards to corporate culture. Failure to integrate may not be immediately evident after the merger, but cultures cannot be changed overnight. Over time, a negative undercurrent will breed miscommunication, making it increasingly difficult for management to control the organization and in the worst-case scenario, result in fraud or scandal. An effective internal audit can help prevent such issues before they arise.
