Japan’s business-to-business (B2B) e-commerce market reached a record ¥514.4 trillion in 2024, achieving a 10.6% year-on-year increase, according to the FY2024 E-Commerce Market Survey released by METI in August 2025.This report examines the current landscape, key growth drivers, and strategic insights for overseas manufacturers seeking to enter Japan’s rapidly digitalizing B2B ecosystem.

1. Market Size and Growth Trends

From 2022 to 2024, Japan’s B2B e-commerce market expanded from ¥420.2 trillion (2022) to ¥465.2 trillion (2023) and further to ¥514.4 trillion (2024).This represents a two-year increase of approximately ¥94 trillion — over 21% total growth — with an average annual growth rate exceeding 10%.The figures underscore a decisive shift toward digital transactions among Japanese enterprises.

2. Sectoral Developments

Growth has been observed across a wide range of industries, particularly in manufacturing, wholesale, and digital corporate services.In areas such as SaaS, cloud-based procurement, and enterprise IT, companies are accelerating their digital transformation to improve purchasing efficiency and transparency.Meanwhile, construction-related and small-to-medium-sized business sectors are progressing at a slower pace, suggesting that regional and sector-specific digital support will remain essential for balanced market expansion.

3. Rising E-Commerce Penetration

The B2B e-commerce penetration rate—the proportion of online transactions among total business trade—rose from 40.0% in FY2023 to 43.1% in FY2024, an increase of 3.1 percentage points.This reflects growing adoption of API-based ordering systems and cloud integration,marking a transition away from traditional EDI frameworks.

4.1 System Integration and Automation

The adoption of API-based transaction platforms and cloud-native systems is streamlining procurement and order management.Industries such as manufacturing and wholesale have seen rapid increases in electronic ordering rates.

4.2 Data Utilization and AI Adoption

Companies are leveraging purchasing and transaction data for demand forecasting, inventory optimization, and supply chain visibility.AI-driven analytics and automated ordering proposals are increasingly implemented to enhance operational efficiency.

4.3 Expansion of Supplier Platforms

A growing number of B2B marketplaces and procurement portals are enabling suppliers to reach a broader customer base,fostering a more open and competitive digital ecosystem.

4.4 Government Support and Policy Alignment

Public initiatives—such as digital transformation subsidies for SMEs and standardization of transaction systems—continue to promote the digitalization of inter-company trade, reducing barriers to entry and improving system interoperability.

5. Strategic Implications for Overseas Manufacturers

5.1 Opportunities and Benefits

With its ¥514 trillion market scale, Japan’s B2B e-commerce sector offers abundant opportunities for large-volume transactions.Digitalization allows suppliers to reduce sales costs and shorten negotiation lead times, making Japan a highly attractive market for cross-border B2B engagement.

5.2 Market Entry Strategies

Successful entry requires adaptation to Japanese business culture, language, and payment practices.Collaboration with local logistics providers and B2B payment solution vendors can facilitate smoother transactions and reduce risk.

6. Future Outlook

Japan’s B2B e-commerce market is entering a new phase focused on automation, intelligence, and sustainability.Key developments include:

AI-driven quotation and inventory optimization to improve cost control and delivery reliability.
Formation of cross-company digital ecosystems enabling integrated supply chain management.
Expansion of sustainable and reusable materials trading to meet environmental goals.

As these trends evolve, Japan’s B2B-EC ecosystem will increasingly balance efficiency and environmental responsibility,creating strategic entry opportunities for overseas manufacturers with advanced technologies and sustainable product lines.
