The Japanese system mandates that Marketing Authorization Holders (MAHs) eliminate paper package inserts for most pharmaceutical products, medical devices, and in vitro diagnostics. Instead, all product information must be made available electronically through designated websites and the PMDA's Safety Information Posting System. This digital transformation ensures that healthcare professionals and patients always have access to the most current safety and usage information, while creating a comprehensive digital trail for regulatory oversight.

Every pharmaceutical product's outer packaging must display a barcode or two-dimensional code that serves as a direct gateway to electronic documentation. When scanned using smartphones or the official PI-navi application, these codes instantly connect users to the product's complete regulatory profile, including package inserts, drug guides, Risk Management Plans, revision histories, and safety alerts. This seamless integration between physical products and digital information creates an unbreakable chain of traceability.

The regulatory framework requires MAHs to maintain extensive digital repositories containing not only basic package inserts but also patient guides, healthcare professional resources, adverse drug reaction manuals, Dear Healthcare Professional Letters, and complete revision histories. This comprehensive approach ensures that all stakeholders have immediate access to critical safety information while maintaining a complete audit trail of all product-related communications and updates.

Japan's system enables continuous monitoring of pharmaceutical products through mandatory registration on the PMDA's Safety Information Posting System. The framework supports real-time updates to product information, immediate distribution of safety alerts, and comprehensive tracking of regulatory changes. This dynamic approach ensures that compliance monitoring occurs in real-time rather than through periodic audits, significantly enhancing patient safety and regulatory oversight.
