Japan vs. Other APAC Markets: Where Should You Expand First?

Introduction

The APAC region presents significant growth opportunities for B2B companies, but choosing the right market is critical. Japan, with a GDP of 4.2 trillion USD (2023), provides stability and high-value contracts, while other APAC markets provide faster growth and lower entry barriers. However, Moody’s Analytics predicts APAC’s economic growth will slow down to 3.7% in 2025, while Japan’s economy is expected to recover after a near-recession from mid -2023 to early 2024. The key question remains: Should B2B companies prioritize Japan or enter other APAC markets first? 

Market Size & Economic Potential for B2B Businesses

Market selection should align closely with the target customer profile and anticipated contract value. Key markets include:

• Japan: The third-largest economy boasts a strong B2B ecosystem in manufacturing, Saas, IT services, and industrial automation. 
• China: The world’s largest market, but with high regulatory risks and intense local competition. 
• Singapore: Business-friendly and ideal for regional HQs and tech startups. 
• South Korea: Advanced digital adoption, with a strong growth in Saas, fintech, and AI. 
• Southeast Asia: High-growth potential but lower B2B maturity.

The optimal entry market varies significantly depending on the industry and business goals. For instance a U.S. based enterprise software company may target Japan for stable, high-value contracts but find faster adoption in Singapore or South Korea due to their openness to Saas. Beyond market size, successful B2B entry requires a deep understanding of each market’s unique business practices. 

Ease of Market Entry & Business Environment

Evaluating a company’s ability to navigate regulatory landscapes and culture nuances is critical for successful market entry, mitigating potential risks and ensuring alignment with local expectations. Notable markets include:

• Japan: Strong infrastructure and legal stability but complex regulations, slow decision-making, and cultural barriers- evidenced by a European cloud security firm’s faster deal closure in Singapore.  
• China: Huge market size but tight regulations, data laws and IP risks- prompting a U.S. robotics firm to choose Japan over China. 
• Singapore & South Korea: Easy setup, fast adoption, and government incentives for B2B tech companies- highlighted by a fintech company’s faster early-stage adoption in Singapore but larger deals in Japan after establishing trust. 

Cost of Doing Business: Japan vs. Other APAC Markets

Japan’s high operational costs which vary depending on location and operation size- such as salaries, office space, and localization are offset by larger enterprise deals with long-term contracts. In contrast, Southeast Asia offers low-cost entry but with smaller B2B contract values and higher customer churn. Singapore, while tax-friendly, faces high costs for acquiring skilled tech talent, ranging between SGD 60,000 to SGD 120,000.  

For example a U.S. AI analytics company found high sales costs in Japan but landed larger deals compared to Southeast Asia, where contracts were smaller and less stable. A thorough cost-benefit analysis is essential to assess each market’s financial visibility. 

Cultural & Business Differences for B2B Expansion

Understanding local business culture and decision-making styles is critical for success:

• Japan: Hierarchical, long decision cycles, and trust-based sales approach.
• South Korea: Also hierarchical but faster decision-making than Japan.
• Singapore: Business-friendly, English-speaking, and direct communication style.
• Southeast Asia: Relationship-driven but price-sensitive, requiring strong partnerships.

For example, a global HR tech firm saw strong early adoption in Singapore but struggled with cold outreach in Japan due to the importance of introductions and trust-building.

Key Lesson: Adapting sales and communication strategies is essential for B2B market penetration.

Key Takeaways: Where Should B2B Companies Expand First?

Japan is ideal for companies that: 

• Target large enterprises with long-term contracts: SaaS, manufacturing, industrial automation. 
• Have resources for localization and cultural adaptation. 
• Operate in industries requiring compliance and regulatory stability: Fintech, AI, cybersecurity. 

Other APAC markets are better suited for firms that:

• Require fast sales cycles and early traction: Saas, fintech, B2B marketplaces. 
• Lack localization resources and prefer English-friendly markets. 
• Operate in cost-sensitive sectors: Logistics, supply chain tech. 

Conclusion

Japan is a high-value but complex market, ideal for B2B companies with long-term commitment. Other APAC markets like Singapore and Korea offer faster entry and scalability with smaller deal sizes. The right choice depends on the industry, sales cycle, and localization ability.
