Growth Drivers of the Japan Molecular Diagnostics Market

1. Rising Cancer Incidence Across the Country

Japan faces a substantial and rising cancer burden, making early detection technologies more critical than ever. Molecular diagnostics helps identify genetic mutations and biomarkers essential for selecting targeted therapies.

In 2022, Japan recorded approximately:

• 1,019,000 new cancer cases
• 380,400 cancer-related deaths

Major cancers—including colorectal, stomach, lung, prostate, and breast cancer—account for roughly 60% of all new cases. This alarming trend underscores why hospitals and oncology centers increasingly rely on molecular testing for better treatment decision-making.

As precision oncology grows, molecular diagnostics will continue to be indispensable in Japan’s cancer management framework.

2. Rapid Technological Advancements

Japan’s molecular diagnostics market is being reshaped by rapid advancements in:

• PCR (Polymerase Chain Reaction)
• Next-Generation Sequencing (NGS)
• Liquid biopsy
• Automation and high-throughput technologies

These breakthroughs have led to faster, more sensitive, and more reliable diagnostic tools.

A notable development occurred in January 2022, when Amoy Diagnostics Co., Ltd. and PREMIA Holdings (HK) Limited introduced the AmoyDx® Pan Lung Cancer PCR Panel (PLC Panel) to the Japanese market. The assay is now reimbursed as an official companion diagnostic for various targeted cancer therapies. This milestone signals the rising acceptance and integration of genomic diagnostics into routine care.

3. Supportive Government Policies and Regulatory Framework

The Japanese government has actively encouraged molecular diagnostics through:

• Reimbursement expansion for molecular tests
• Investments in precision medicine and genomic databases
• Streamlined regulatory approvals
• Funding for academic research and biotech innovation

These initiatives help hospitals upgrade diagnostic capabilities and support the commercialization of advanced technologies. Japan’s national focus on healthcare digitization and personalized medicine is expected to further accelerate adoption across the next decade.

Market Challenges
