Define Protected Information and Match Obligations to the Transaction
A non-disclosure agreement, or NDA, protects important information shared during a transaction. It specifies what is confidential and which actions are prohibited. Vague terms may fail to protect information while placing heavy obligations on one party.
Pay particular attention to definitions, permitted use, return or destruction, duration, and liability. Adapt a template to the transaction. This article explains general practices in a Japanese business context; it is not legal advice for an individual matter. Important transactions require a lawyer’s review.
What an NDA Does
NDA stands for Non-Disclosure Agreement, called a himitsu hoji keiyakusho in Japanese. It seeks to prevent disclosure to outsiders, use beyond the agreed purpose, and improper handling of information shared in discussions or transactions.
Information may include:
- Technical information
- Customer information
- Sales materials
- Financial information
- Plans under development
- Partnership discussions
Typical situations include outsourcing, joint development, partnership negotiations, early M&A discussions, and sharing internal details with job candidates.
An NDA has three main roles.
| Role | Content |
|---|---|
| Prevent disclosure | Restrict sharing with third parties |
| Prevent unauthorized use | Limit use to the agreed purpose |
| Establish a basis for disputes | Clarify responsibility and responses to a breach |
It supports trust and establishes a reference point if trouble occurs. Define what is protected in writing instead of relying on an oral promise.
Unilateral and Mutual Agreements
The two main arrangements are unilateral and mutual disclosure. The arrangement affects how you read the terms.
A unilateral agreement suits information flowing from one party. For example, outsourcing may involve sharing only your company’s customer information and workflow.
A mutual agreement suits both sides sharing information, as in partnership or joint-development discussions involving each party’s technology and sales information.
| Arrangement | Typical situations | Point to examine |
|---|---|---|
| Unilateral | Outsourcing and information sharing before a proposal | Terms may favor the disclosing party |
| Mutual | Partnerships, joint development, and M&A discussions | Check whether obligations are symmetrical |
A mutual label does not ensure fairness. Wording may still put a heavier burden on one side. Examine the actual terms.
Reviewing the 12 Essential NDA Items
Review the purpose, scope of information, obligations, and arrangements after termination. The following groups cover the practical checks discussed here.
Purpose and Definition of Confidential Information
Specify why information is disclosed and what qualifies as confidential. Ambiguity weakens restrictions on use.
Check:
- Whether the contractual purpose is specific
- Whether the information definition is too broad
- Treatment of oral disclosures
- Whether confidentiality markings are required
- Whether the agreement’s existence is confidential
Exclusions also matter. Agreements often exclude:
- Information already public
- Information held before receipt
- Information lawfully obtained from a third party
- Independently developed information
- Information becoming public without the recipient’s fault
Without exclusions, the recipient may face an excessive burden.
Use Restrictions and Management
Establish who can see the information, whether copying is allowed, and whether outside advisers can receive it, alongside the prohibition on leaks.
Review:
- Restrictions on third-party disclosure
- Restrictions on use outside the purpose
- Limits on copying and reproduction
- Limits on authorized access
- Conditions for sharing with subcontractors or advisers
- Reporting duties after a leak
Practical work may require sharing with lawyers, tax accountants, audit firms, or a parent company. The terms should address those needs.
Return, Destruction, Duration, and Liability
Termination arrangements and liability can be overlooked at signing but become critical in a dispute.
Review:
- Return obligations when the agreement ends
- Methods for deleting or destroying data
- Whether destruction certification is required
- Contract duration
- Survival of confidentiality obligations
- Damages
- Injunctive relief
- Governing law
- Agreed jurisdiction
Survival periods deserve particular attention. Japanese business arrangements often continue duties for several years after termination for technical or customer information. An indefinite obligation can also be too burdensome for a recipient. Match the period to the information’s nature.
Using a Template Carefully
Templates need adaptation to the transaction, as discussed with reference to this Japanese Ministry of Economy, Trade and Industry document. A BUSINESS LAWYERS explanation also covers key terms such as purposes, definitions, exceptions, return or destruction, and damages.
Common template problems include:
- An excessively broad information definition
- A vague purpose reused across transactions
- Duties inconsistent with actual operations
- Impractical return or destruction procedures
- Unclear limits on damages
- Unadjusted governing law or jurisdiction for overseas matters
A broader definition does not automatically give better protection. Excessive breadth can make compliance unmanageable; too narrow a definition can leave important information exposed. Adjust it to the case.

For Japan, the cited explanations describe NDAs as capable of being concluded on paper or electronically. They discuss electronic agreements as valid and not subject to Japanese stamp duty (LegalOn, Docusign Japan). Ordinary paper NDAs are also generally described as outside the taxable document categories and not requiring a Japanese revenue stamp (BUSINESS LAWYERS, Nagase Law Office). These points concern the Japanese context.
Information Management Makes the Agreement Work
An NDA functions through information handling consistent with its terms after signing. The METI reference document also emphasizes operational controls alongside the contract.
Practical controls include:
- Labeling confidential information
- Setting access permissions
- Recording recipients
- Limiting the sharing scope
- Reviewing former employees’ and contractors’ access
- Establishing a leak-reporting route
Strict terms achieve little if everyone internally can access the information freely. The agreement also provides a starting point for information-management rules.

Frequently Asked Questions
Q: Can I sign the other party’s NDA without changes?
A: Review it first because it may favor the other party. At minimum, examine definitions, permitted use, duration, damages, and jurisdiction.
Q: Does an NDA need a revenue stamp?
A: In the Japanese context discussed here, an ordinary confidentiality agreement is generally described as outside stamp-duty taxable document categories and not requiring a revenue stamp.
Q: Can an NDA be concluded electronically?
A: In Japan, the cited explanations describe NDAs concluded through electronic contract services as valid and not requiring a revenue stamp.
Q: Is a slightly edited template enough?
A: It depends. A template can provide a basis for ordinary transactions. Joint development, M&A, and important technical disclosures need individual adjustment. Have a lawyer review important matters.
