Field Notes
Choosing Japanese GAAP or IFRS for a first statutory audit
A practical comparison for companies deciding which reporting framework will govern their first independent audit in Japan.
The framework choice shapes disclosures, estimate language, and often the lender’s comfort letter. For many private Japanese companies, Japanese GAAP remains the natural path. Groups with overseas parents may need IFRS for consolidation even when local statutory filings stay on Japanese GAAP.
Where the frameworks diverge in daily work
Revenue cut-off, lease classification, and impairment testing are the areas where draft packs most often need revision mid-audit. IFRS tends to demand more narrative around judgments; Japanese GAAP packs we see locally still rely heavily on schedule-based evidence and stamped approvals.
Questions worth asking before the engagement letter
Who reads the statements — a regional bank in Sendai, a Tokyo private equity desk, or a German parent controller? Will you need English translations of the notes? Is there a planned listing or sale within three years? Answers to those questions matter more than abstract preference for one standard set.
Blue Coast Audit Cabinet will not push a framework for its own sake. We will map the filing calendar, the bank covenants, and the parent reporting pack, then write the engagement letter around the framework you actually need to live with.
