Japan or Indonesia? Two Asian Markets, Two Very Different Business Opportunities

Asia continues to be a major destination for international business expansion, but choosing the right market requires more than simply looking at economic growth. Japan and Indonesia illustrate this particularly well.

Japan offers a mature, high-value market supported by advanced infrastructure, strong purchasing power, and an established corporate ecosystem. Indonesia, meanwhile, combines a large and relatively young population with stronger economic growth and an expanding consumer market. According to BPS-Statistics Indonesia, the Indonesian economy grew by 5.11% in 2025, while Japan continues to face a very different structural challenge: an aging and declining population.

For international companies, this creates two distinct opportunities. Japan may offer greater potential for businesses competing on quality, specialization, technology, and premium value, while Indonesia may be particularly attractive to companies seeking growth, scale, and access to a developing consumer market.

However, market potential is only part of the equation. Labour availability, language, taxation, business culture, local relationships, and regulatory requirements can significantly affect the cost and complexity of entering either country.

So, what does doing business in Japan actually look like compared with Indonesia?

Based on the latest available official statistics and market information, we examine seven key differences international companies should consider before entering these two markets.

Doing Business in Japan vs. Indonesia: 7 Key Differences for International Companies

For international companies looking to expand in Asia, Japan and Indonesia represent two very different business opportunities.

Japan offers a mature economy, sophisticated infrastructure and an established corporate market, while Indonesia combines a large workforce with relatively strong economic growth.

For companies considering either market, understanding the differences in demographics, taxation, language, workforce and business practices can help shape a more effective market-entry strategy.

1. Market Growth

Japan is a mature, high-income economy with strong purchasing power and an established corporate market. For international businesses, opportunities can be particularly attractive in sectors where customers value quality, technology, specialization and reliability.

Indonesia presents a different growth profile.

According to BPS-Statistics Indonesia, Indonesia’s economy grew by 5.11% in 2025, compared with 5.03% in 2024. GDP at current market prices reached approximately IDR 23,821.1 trillion, while GDP per capita reached approximately IDR 83.7 million (US$5,083.4).

For companies pursuing growth and scale, Indonesia therefore represents an increasingly important Southeast Asian market.

2. Demographics and Labour

Demographics represent one of the clearest differences between the two markets.

According to the Statistics Bureau of Japan, Japan’s estimated population stood at approximately 122.93 million in July 2026, around 440,000 lower than one year earlier.

Official February 2026 data also showed approximately 36.2 million people aged 65 or above, compared with approximately 73.4 million people aged 15–64. 

This demographic structure contributes to the recruitment challenges facing many businesses operating in Japan.

Indonesia, meanwhile, has a substantially larger labour pool. According to BPS, its labour force reached approximately 154.0 million people in August 2025, an increase of 1.89 million from August 2024. Approximately 146.54 million people were employed. 

However, a large labour supply should not automatically be interpreted as readily available skilled labour. Foreign companies still need to consider education, professional skills, training and regional differences when developing their recruitment strategies.

3. Language Environment

Language can be an important consideration when entering Japan.

Japanese remains the primary language for much domestic business communication. JETRO’s surveys of foreign-affiliated companies have also identified foreign-language communication as one of the challenges companies encounter when operating in Japan.

As a result, companies dealing extensively with Japanese customers, suppliers, authorities or domestic partners may need Japanese-speaking employees or professional support.

Indonesia can offer greater flexibility in English communication within multinational companies and major commercial centres such as Jakarta. Nevertheless, companies planning broader operations should not assume that English alone will be sufficient across the entire market.

Local-language capability and Indonesian employees or partners can therefore remain important for market development and day-to-day operations.

4. Corporate Taxation

The two countries also have different corporate tax environments.

Japan’s national corporate tax rate for ordinary corporations is generally 23.2%, according to Japan’s Ministry of Finance. However, businesses may also be subject to local and enterprise taxes. 

The Ministry of Finance’s standard comparison shows a combined national and local effective corporate tax rate of approximately 29.74% under its standard calculation.

Indonesia generally applies a 22% corporate income tax rate, although specific companies may qualify for different treatment, incentives or reductions depending on their circumstances.

Tax rates alone therefore should not determine market-entry decisions. Companies should consider the complete tax structure, applicable incentives and their proposed corporate structure in each country.

5. Workforce and Working Environment

Japan’s business environment tends to be highly structured, with considerable emphasis on preparation, quality control, punctuality and internal processes. For international companies, this can provide predictability and operational discipline, but decision-making and approval processes may take longer than expected.

Indonesia also places importance on hierarchy, but personal relationships can have a stronger influence on day-to-day business interactions. Communication may be more indirect, and relationship-building can be particularly important when working with local partners and decision-makers.For international management teams, adapting communication and leadership styles to the local environment can therefore be just as important as adapting the product itself.

6. Market-Entry Barriers

Foreign businesses entering Japan often need to invest significant time in establishing credibility and trust.

JETRO research involving foreign-affiliated companies has identified issues such as foreign-language communication, administrative procedures, finding business partners and Japan-specific regulations and business practices as challenges to operating in the Japanese market.

This means that having a strong product or service may not be sufficient by itself. Localization, reputation and a reliable local network can significantly influence market-entry progress. In Indonesia, local relationships and networks can also play an important role. Companies may need to navigate regulatory requirements, regional differences and administrative procedures while developing relationships with local partners and stakeholders.

The nature of the challenge is therefore different: Japan can require substantial localization and credibility-building, while Indonesia may require greater attention to local networks and regulatory navigation.

7. Overall Business Opportunity

Ultimately, Japan and Indonesia should not simply be viewed as an “easy market” versus a “difficult market.” They offer different combinations of opportunity and complexity.

Japan may be particularly attractive for companies seeking:

• High-value customers
• Advanced infrastructure
• An established corporate market
• Opportunities for specialized or premium products and services

However, companies should be prepared for demographic pressures, recruitment challenges, language requirements and potentially longer business-development cycles.

Indonesia may be attractive for companies seeking:

• Faster economic growth
• A large labour and consumer base
• Long-term market expansion
• Access to one of Southeast Asia’s largest economies

At the same time, businesses should carefully consider talent availability, local regulations, regional differences and the importance of local relationships.

Which Market Is Right for Your Business?

The answer depends on the company’s industry, target customers, pricing strategy, workforce requirements and long-term objectives. Japan may offer greater opportunities for companies prioritizing purchasing power, quality and specialization, while Indonesia may provide stronger potential for companies prioritizing growth, scale and access to an expanding market.

In both countries, successful expansion requires more than identifying market demand. Companies need to understand the local regulatory environment, taxation, workforce, language and business culture before committing significant resources. For international companies considering expansion into Japan or Indonesia, developing a market-entry strategy based on reliable local information and official data can help reduce risk and build a stronger foundation for sustainable growth.
