Best Cyber Law, Data Privacy and Data Protection Lawyers in Shizuoka

About Cyber Law, Data Privacy and Data Protection Law in Shizuoka, Japan

Cyber law, data privacy and data protection in Shizuoka are governed principally by national Japanese laws and regulations that apply across all prefectures, together with local enforcement and support from Shizuoka public authorities. The core national framework is the Act on the Protection of Personal Information - commonly called APPI - which sets out duties for businesses and public bodies that collect, use and transfer personal data. Other important laws include the Act on Prohibition of Unauthorized Computer Access, provisions of the Penal Code that cover computer-related offenses, the Unfair Competition Prevention Act for trade secrets, and national cybersecurity policy instruments and guidance issued by government agencies.

Practically, individuals and organizations in Shizuoka follow the same legal standards as those in Tokyo or other prefectures. Local authorities - such as the Shizuoka Prefectural Government, municipal offices and the Shizuoka Prefectural Police - provide on-the-ground enforcement, guidance and incident response. Businesses operating in Shizuoka that handle personal data must meet APPI requirements, take reasonable security measures, respect data-subject rights, and address cross-border transfer rules when sending personal information overseas.

Why You May Need a Lawyer

- Receiving a data subject request - for access, correction, deletion or disclosure - where complex legal balancing or exemptions apply.

- Advising on employee monitoring, cybersecurity controls, or handling trade-secret leaks and insider threats.

- Representing your business in administrative proceedings before the Personal Information Protection Commission or in civil litigation for damages or injunctions.

Local Laws Overview

This overview highlights the key legal aspects relevant in Shizuoka - most of which are national rules applied locally:

- Act on the Protection of Personal Information (APPI) - APPI sets principles such as purpose specification, data minimization, security safeguards, and data-subject rights like access and correction. The law requires reasonable security measures and, in certain cases, notification to affected persons and the Personal Information Protection Commission when a breach occurs.

- Act on Prohibition of Unauthorized Computer Access - criminalizes unauthorized access to computer systems and can lead to investigation and prosecution by police.

- Penal Code provisions - cover fraud, blackmail, defamation and other crimes that often arise in cyber incidents.

- Unfair Competition Prevention Act - protects trade secrets and provides civil remedies for misappropriation or disclosure of confidential business information.

- Sectoral rules and special regimes - specific sectors such as healthcare, finance, education and local government may have additional rules on handling sensitive data, including My Number information which is strictly regulated.

- Cross-border transfers - APPI requires that transfers of personal data to overseas recipients be accompanied by appropriate safeguards or valid legal bases - often through consent, contractual clauses, or other protective measures.

- Administrative enforcement - the Personal Information Protection Commission (PPC) oversees APPI enforcement nationwide. Local police and prosecutors handle cybercrime investigations. Shizuoka municipal and prefectural bodies may issue guidance or coordinate incident response locally.

Frequently Asked Questions

What counts as personal information under Japanese law?

Under APPI, personal information is data that can identify a living individual - directly or indirectly - such as names, addresses, phone numbers, email addresses and identifiers that can be linked to a person. Special-care-required personal information - like health data, race, medical history and My Number identifiers - is subject to stricter handling rules.

What should I do immediately if I suspect a data breach?

Take these steps promptly: contain and secure systems to stop ongoing loss, preserve evidence, assess scope and affected individuals, implement mitigation to prevent further damage, and notify internal stakeholders. Then consult legal counsel to determine whether you must notify affected persons and the Personal Information Protection Commission, and whether to report to police in Shizuoka if a crime is suspected.

When am I required to notify individuals or regulators about a breach?

APPI requires business operators to take appropriate measures when leaks or improper access occur. Notification obligations depend on the severity and nature of the breach, the types of data involved and the risk of harm to individuals. Legal advice is important to assess notification thresholds, timing and content of disclosures to comply with APPI while managing legal risk.

Can I transfer personal data outside Japan from Shizuoka?

Yes, but transfers are subject to APPI obligations. You must ensure that overseas recipients provide an equivalent level of protection - for example, through contractual safeguards, documented consent or other appropriate measures. For sensitive categories or government identifiers like My Number, additional restrictions apply. A lawyer can help design transfer mechanisms and contractual clauses.

What are the penalties for violating data protection rules?

Penalties vary. Administrative actions by the PPC can include orders to improve practices, public disclosure of violations and fines in certain cases. Violations that also constitute criminal offenses - such as unauthorized computer access or misuse of specific identifiers - can lead to prosecution, fines and imprisonment under criminal law. Civil claims for damages are also possible.

Can employers in Shizuoka monitor employee communications?

Employers may monitor workplace systems within reasonable limits for security, productivity and legal compliance. However, monitoring must respect privacy expectations, be justified and proportionate, and be disclosed in policies. Handling of personal data from monitoring must comply with APPI - purpose limitation, minimization and proper safeguards are required. Obtain legal advice before implementing employee monitoring tools.

What if I am accused of committing a cybercrime?

If you face a criminal investigation or charge, seek a lawyer immediately. Do not delete potential evidence, and avoid making detailed statements without counsel. A qualified criminal defense attorney with cyber expertise can advise on rights during police questioning, preserve legal defenses and coordinate with technical experts to review evidence.

How do I exercise my rights to access, correct or delete my personal data?

Submit a formal request to the organization holding your data. APPI provides rights to access and request correction or deletion, subject to certain exemptions. The controller must respond within a reasonable period. If you cannot resolve the matter with the organization, the Personal Information Protection Commission and local dispute-resolution services can help, and a lawyer can assist with formal complaints or litigation.

What should small businesses in Shizuoka do to comply with data protection law?

Key steps include: identify the personal data you collect and why; limit collection and retention; adopt written privacy policies and internal rules; implement reasonable security measures; train staff on data handling; prepare incident response processes; and ensure contracts with vendors impose necessary safeguards. A lawyer can help tailor compliance to your business size and risk profile.

How do I find a lawyer in Shizuoka who understands cyber and data protection law?

Look for attorneys with experience in IT, privacy and cybercrime. Consider members of the Shizuoka Bar Association who list privacy or IT law among their specialties. Ask about experience with APPI enforcement, data breach response, cross-border transfers and criminal defense in cyber matters. Check whether the lawyer can communicate in your preferred language or work with translators when needed.
