4. Frequently Asked Questions

What is APPI and who must comply?

APPI is Japan's main privacy law. It applies to business operators handling personal information in Japan or abroad in some cases. Both large and small enterprises in Naha must comply if they process personal data.

What should I do if there is a data breach in my Naha business?

Identify the breach, contain it, assess the scope, and notify affected individuals and the regulator as required by APPI. Prepare a breach response plan and document the incident for potential enforcement actions.

How do cross-border data transfers work under APPI?

Transfers to foreign entities require safeguards such as contract terms and appropriate data protection measures. The rules emphasize adequate protection standards in the destination country or organization.

Where can I find the official law texts for APPI?

Official texts are available on the e-Gov portal. For guidance, use the Personal Information Protection Commission materials as a companion resource.

Why might I need a Data Processing Agreement with a vendor?

A DPA clarifies roles, responsibilities, and security measures for personal data. It helps prevent data breaches and ensures compliance with APPI and the My Number Act.

Do I need a privacy officer or similar role in my small Naha business?

While not always mandatory, appointing a privacy or data protection lead helps manage risk, document data flows, and handle inquiries from customers or regulators.

Should I hire a lawyer for APPI compliance

Yes, especially if handling large datasets, sensitive data, or cross-border transfers. A lawyer can tailor policies, review contracts, and prepare breach response plans.

Is standard contractual data protection language enough for cross-border transfers?

Standard clauses may be helpful but are not always sufficient. A lawyer can customize protections to align with APPI and ensure enforceability in relevant jurisdictions.

How long can a company retain personal data?

Retention should align with the purpose of collection and legal requirements. A lawyer can help define retention periods and establish secure deletion practices.

What is the difference between personal data and sensitive data under APPI?

Personal data identifies an individual. Sensitive data involves special categories such as health, race or biometrics, requiring stricter handling and consent standards.

How much can penalties be for APPI violations?

Penalties vary by violation type and severity, potentially including fines and corrective orders. A lawyer can help assess exposure and strategize response.
