Due Diligence (DD): The Seller’s Perspective
Japan Financial Strategy Center (JFSC) CEO Yuichi Igarashi emphasizes that due diligence (DD)—independent analysis that does not constitute investment, legal, or tax advice—marks the exact pivot point where transaction leverage shifts from seller to buyer. The SME M&A Guidelines (3rd edition) issued by the Ministry of Economy, Trade and Industry (METI) similarly define DD as the critical phase for determining the final terms of a share transfer or business transfer.
Prior to DD, the seller holds the upper hand while evaluating multiple letters of intent (LOIs) to select a buyer. Once DD commences, however, the seller faces intensive scrutiny—dozens of financial and legal queries, massive document requests, and all-day management interviews conducted by law firms. This process often feels like an interrogation, creating a severe psychological burden for sellers; JFSC actively mitigates this stress through comprehensive pre-DD preparation and hands-on, on-site support.
Purpose of Due Diligence (DD): The Duty of Care Perspective
While due diligence (DD) is often simplified as a tool to determine final transfer consideration, this content—which is independent analysis and does not constitute investment, legal, or tax advice—views it as a multi-dimensional corporate governance requirement. For an acquiring company / buyer-side organized as a joint-stock corporation, the final acquisition decision rests with the board of directors, whose members owe a statutory duty of care under Article 330 of the Companies Act.
Post-closing discovery of latent defects exposes directors to shareholder accountability and potential director liability suits. Proper DD serves as affirmative evidence that the board fulfilled its duty of care. Framing DD not as a mere price-reduction tactic, but as an essential corporate governance protocol, reduces the seller's psychological burden during a business succession or divest transaction.
Voluminous Information Requests as Indicators of M&A Intent
Extensive documentation requests signify strong buyer intent. The buyer bears all due diligence (DD) costs; engaging law and accounting firms on a large scale represents a significant financial commitment, reinforcing their motivation to close. Furthermore, buyer-side deal teams face severe internal career risks if transactions collapse after incurring substantial DD expenses.
The presence of outside directors under Article 2, Item 15 of the Companies Act requires careful navigation. These independent directors—often attorneys or certified public accountants (CPAs)—actively scrutinize material decisions like M&A to safeguard shareholder interests. Consequently, buyer deal teams must convince both executive management and outside directors; any display of an arrogant, buyer-dominant attitude during this process sharply increases deal-break risks.

This thoroughness reflects serious buyer commitment—recognizing this dynamic and responding transparently is the fastest path for a seller to build trust and achieve a clean exit timeline.
Reasons for Post-Due Diligence Valuation Reductions: Accounting Standard Discrepancies
Few buyers actively risk breaking a deal solely to force a price reduction. Valuation adjustments typically stem from fundamental structural differences between tax accounting and financial accounting frameworks—this content is independent analysis and does not constitute investment, legal, or tax advice.
Most Japanese SMEs (Small and Medium-sized Enterprises) use tax accounting, meaning they omit provisions like employee retirement benefits because they are not tax-deductible until paid. Conversely, listed corporate buyers must use financial accounting—a framework under Financial Services Agency (FSA) oversight requiring conservative estimates and explicit recognition of retirement benefit liabilities.
Listed buyers must establish these provisions post-closing, frequently reducing the final transfer consideration to offset the unrecognized liabilities. If an M&A advisor fails to explain this GAAP gap proactively, the seller may falsely assume the buyer utilized DD merely as a price-lowering tactic, collapsing the deal. Sellers should collaborate with their corporate tax accountants or CPAs early to model a financial accounting-based valuation before entering a clean exit timeline.
The Core Purpose of Due Diligence: Creating a Post-Merger Roadmap
While due diligence (DD) frequently focuses on valuation mechanics, its core function is operational planning. Ministry of Economy, Trade and Industry (METI) publications consistently emphasize post-merger integration (PMI) viability—leading private equity practitioners frame DD as a joint blueprinting exercise for post-closing ops.
The DD process maps out critical operational parameters—business risks, process bottlenecks, and synergy drivers. Using this phase to align integration priorities between buyer and seller significantly increases PMI success. This content is independent analysis and does not constitute investment, legal, or tax advice; restricting information flow or providing inaccurate explanations triggers buyer distrust, disrupting the clean exit timeline and threatening deal survival.
Lowering Deal-Break Risks Through Professional Collaboration and Early Disclosure
Due diligence (DD) requires multi-disciplinary coordination—tax treatments managed by corporate tax accountants, contractual terms by attorneys, labor transitions by labor and social security attorneys, property valuations by real estate appraisers, and share pricing by CPAs. Systematic data disclosure from day one—combined with proactive explanations of GAAP gaps via a trusted M&A advisor—repositions DD from a raw price negotiation into a collaborative integration alignment.
