(Singapore) – For many people outside Japan, the country’s economy can look like a paradox. Japan is home to global companies such as Toyota, Sony, Hitachi, Mitsubishi, Mitsui and SoftBank, yet its domestic economy faces slow population growth, an ageing society and structural limits on expansion.
For international readers considering business with Japan, however, macroeconomic statistics tell only part of the story. The country’s low interest rates, mature domestic market, demographic pressures, overseas expansion, acquisition strategy and relationship-driven business culture all help explain how Japanese companies make decisions and where they look for growth.
1. Deposit interest rates remain low
The first thing to understand is that interest rates in Japan remain low by international standards. The Bank of Japan ended its negative interest-rate policy in 2024 and subsequently raised its policy rate several times, reaching 0.75% in December 2025, but financial conditions remain relatively accommodative.
For households and companies, this represents a major change from the high-interest environments found in many other economies. Japan spent decades with extremely low interest rates, which shaped corporate financing, household savings and investment behaviour, even as the country has now entered a gradual process of monetary normalisation.
2. Japan is an exceptionally mature domestic market
Japan has highly developed infrastructure, sophisticated distribution networks and deep market penetration across many industries. A new company entering the market therefore often faces established brands, long-standing suppliers, mature distribution channels and customers who already have several choices.
That makes domestic expansion structurally more difficult in many sectors. The OECD notes that Japan has experienced sluggish productivity growth over the past decades and that firms’ growth expectations were shaped by the aftermath of the asset-price bubble, reducing incentives to expand domestic production capacity.
3. Demographics are one of Japan’s biggest economic challenges
Demographics are perhaps the most important factor for anyone trying to understand Japan’s long-term business environment. Japan has one of the world’s oldest populations, and the working-age population has been shrinking for decades.
The OECD says Japan’s working-age population fell from 87.3 million in 1995 to 73.7 million in 2024, a decline of about 16%. The ageing population is creating pressure on labour supply, public finances and long-term economic growth.
4. Labour shortages are becoming a business issue
An ageing population means Japan is not simply dealing with fewer consumers. Companies are also facing a smaller pool of available workers.
The consequences can be seen across manufacturing, construction, logistics, restaurants, healthcare and other service industries. Japanese companies are increasingly turning to automation, robotics, older workers, greater female labour participation and foreign workers to address labour shortages. The OECD specifically identifies greater use of foreign workers, higher female participation and labour-market reforms as important responses to Japan’s demographic challenge.
5. Japanese companies increasingly look overseas for growth
When the domestic market offers limited room for volume expansion, international markets become increasingly important. Japanese companies have responded by expanding production, sales networks and investment outside the country.
The trend is visible in Japan’s outward investment. JETRO reported that Japanese outward foreign direct investment reached US$217.8 billion in 2025, up 5% from the previous year and remaining above US$200 billion for the second consecutive year.
A Japanese company entering a foreign market may establish a new subsidiary, build a factory, open a sales office, form a joint venture or acquire an existing local company. The choice depends on the speed of expansion required, access to customers, technology, local management and the strategic importance of the market.
6. Overseas M&A has become an important growth strategy
Cross-border acquisitions have become particularly significant for Japanese companies. JETRO data based on LSEG transactions show that Japanese outbound M&A reached US$110.9 billion in 2025, almost double the previous year’s figure and the second-highest annual total on record after the 2019 peak of US$155.8 billion.
There were 666 outbound M&A transactions in 2025, including 17 deals valued at more than US$1 billion. The United States remained the largest destination by number of transactions, with 175 deals, while Japanese companies also continued to explore opportunities across Asia and other emerging markets.
For international companies, this creates an important opportunity. A Japanese company looking overseas may not necessarily be looking only for a supplier or distributor. It may be looking for a local platform, technology company, customer base, management team or acquisition target that can accelerate its international growth.
7. Long-term relationships matter in Japanese business
Another characteristic that international executives should understand is the importance placed on long-term relationships, reputation and trust. This does not mean that Japanese companies will only work with people they already know, but credibility can play an important role in the early stages of a business relationship.
For a foreign company approaching a Japanese corporation, the process may therefore involve several meetings and discussions before the commercial opportunity becomes concrete. The Japanese side may want to understand the people behind the company, its reputation, its track record and the potential for a relationship that can continue beyond a single transaction.
8. Personal referrals and established networks can open doors
A trusted introduction can be particularly useful when entering the Japanese business environment. A referral from an established business partner, bank, Japanese corporation, industry contact or long-standing professional relationship can provide context and credibility that a completely cold approach does not necessarily have.
This does not replace due diligence or commercial evaluation. It can, however, help create the initial level of trust needed for both sides to invest time in understanding a potential partnership.
For foreign companies seeking Japanese partners, this means relationship-building should be viewed as part of the business process rather than simply as a social exercise. The quality of the introduction, the reputation of the person making it and the history between the parties can influence how quickly a conversation develops.
9. Decision-making can take time
Another feature frequently noticed by foreign executives is the time required for internal decision-making. Large Japanese corporations often involve multiple departments and management levels before reaching a final decision, particularly when the proposed transaction carries financial, operational or reputational consequences.
For an overseas partner accustomed to a highly centralised decision-making structure, this can appear slow. JETRO surveys of business perceptions in ASEAN have identified slow decision-making and organisational rigidity among challenges associated with Japanese companies, while respondents also highlighted reliability, integrity and long-term commitment as positive characteristics.
The practical implication is that foreign companies entering negotiations with Japanese corporations often need patience. A meeting that appears exploratory at first can be part of a much longer internal process involving technical reviews, legal checks, management discussions and consensus-building.
10. Japan is not simply a slow-growth economy. It is searching for a new growth model
The final point is perhaps the most important. Describing Japan simply as an economy with little growth misses the changes taking place beneath the surface.
The OECD expects Japan’s real GDP to grow by around 0.6% in 2026 and 0.8% in 2027, with domestic demand remaining an important driver. At the same time, the organisation identifies productivity, business dynamism, digitalisation, innovation and foreign investment as important areas for improving Japan’s longer-term growth potential.
This creates an unusual business environment. Japan has a huge installed economic base, sophisticated companies, advanced technology and substantial corporate financial resources, while its ageing population and mature domestic market limit some forms of traditional expansion.
The result is a growing emphasis on automation, artificial intelligence, healthcare, services for older consumers, energy, digitalisation and overseas markets. For international businesses, understanding Japan therefore requires looking beyond the country’s headline GDP growth rate and examining where Japanese companies are deploying capital, technology and management resources next.
For foreign executives, investors and potential business partners, these ten characteristics provide a useful starting point for understanding Japan. The country may offer fewer opportunities for simple volume-driven domestic expansion than a fast-growing emerging market, but its mature companies are increasingly looking for new opportunities through technology, productivity improvements, international expansion and cross-border M&A.
That is why understanding how Japanese companies think about growth can be just as important as understanding Japan’s economic statistics. For a foreign company hoping to work with Japan, the opportunity may ultimately lie not only in selling into Japan, but also in becoming part of the next international growth strategy of a Japanese company.
