Field Notes

Setting materiality when your Japanese entity sits between SME and listed group scales

Spreadsheet printouts used while setting audit materiality

Materiality is not a single percentage pulled from a pocket guide. For companies whose revenue sits between a few hundred million and several billion yen, the benchmark choice—profit before tax, total assets, or equity—can shift fieldwork by weeks.

We begin with the user’s of the statements. A subsidiary feeding a listed overseas parent often needs tighter thresholds on related-party balances than a domestic trading company whose lenders focus on working capital covenants.

Practical steps include documenting why a particular base was chosen, recording qualitative factors such as thin capitalization or first-year IFRS adoption, and agreeing performance materiality with the engagement partner before the first sample is drawn.

Clients who prepare a draft materiality memo with their own finance team before our planning meeting usually clear planning points faster and avoid last-minute scope surprises near filing.
