- Act on Regulation of Transmission of Specified Electronic Mail: Controls commercial email and requires opt-in or clear opt-out mechanisms, accurate sender information and adherence to anti-spam rules.

Frequently Asked Questions

Do I need to register my online shop with any Nagasaki office?

There is no special "online shop" registration separate from your business registration. You must register your business structure under corporate or sole proprietor rules at the Legal Affairs Bureau for company registration, and notify tax offices for consumption tax and income tax purposes. Local municipal offices can guide registration processes and licenses that apply to specific product categories, for example food or medical goods.

What information must appear on my website under Japanese law?

Under the Act on Specified Commercial Transactions you must display clear seller information - business name, representative name, physical address, phone number, prices including shipping, payment methods, delivery times, and return or cancellation policies. If you operate subscription services or telemarketing, additional disclosure obligations apply. Even if you are based in Nagasaki but sell nationwide, apply these national rules.

How should I handle customer personal data to comply with Japanese law?

Publish a clear privacy policy explaining the purpose of data collection, retention periods, third-party sharing and how data subjects can exercise rights. Implement appropriate technical and organizational security measures, limit data collection to what is necessary, and follow rules for cross-border transfers. If a data breach occurs, prepare an incident response plan and follow notification obligations where applicable.

Are electronic contracts and signatures legally valid in Japan?

Yes. Electronic contracts are generally enforceable if they meet requirements for identifying the parties and demonstrating agreement. Electronic signatures can have legal effect when they reliably indicate intent and integrity. For high-value or sensitive transactions consult a lawyer to design signature and authentication processes that meet legal and evidentiary needs.

What do I do if a customer files a complaint or a refund claim?

First review your published terms and the applicable consumer protection laws. Try to resolve the dispute through clear communication and a reasonable refund or return process. If the dispute escalates, local consumer centers or alternative dispute resolution may assist. If legal claims are threatened, consult a lawyer promptly to assess liability and defenses.

How should I respond to allegations of copyright or trademark infringement?

If you receive an infringement notice, preserve relevant records and evaluate the claim with legal counsel. Take swift remedial steps if the claim is valid, such as removing infringing content, and consider legitimate defenses like fair use or licensing. Platforms often have specific notice-and-takedown procedures; follow those procedures to limit exposure to liability.

What are my obligations if my site is hacked or personal data is leaked?

Under applicable laws and best practice, you should contain the breach, assess scope and impact, secure systems, preserve evidence and notify affected individuals where their data is at risk. For significant breaches, administrative notification to the Personal Information Protection Commission and coordination with law enforcement may be required. Consult a lawyer experienced in data breaches to manage legal, regulatory and public relations aspects.

Can consumers cancel online purchases easily in Japan?

Consumer cancellation rights vary by transaction type. While some door-to-door style sales have statutory cooling-off rights, ordinary online sales do not automatically grant a general unconditional cancellation right unless specified in your terms. However, misleading advertising, undisclosed fees or defective goods can trigger statutory remedies. Be transparent about cancellation and return policies to reduce disputes.

Do I need to collect Japanese consumption tax for online sales?

Generally, consumption tax applies to sales of goods and services in Japan. If your business exceeds the taxable threshold, you must register and charge consumption tax on domestic sales. Cross-border sales have specific rules depending on whether you supply digital services to consumers or businesses outside Japan. Consult a tax advisor familiar with e-commerce taxation and local tax office rules.

How do I find a qualified lawyer in Nagasaki for e-commerce issues?

Start with the Nagasaki Bar Association for referrals to lawyers experienced in internet and commercial law. Consider lawyers who handle privacy, consumer disputes, IP and cyber incidents. Ask about experience with online marketplaces, cross-border disputes and relevant regulatory bodies. Confirm fee structures, language capabilities if you need English support, and whether the lawyer offers an initial consultation.
