Japan is entering 2026 with a momentum few could have anticipated. In 2023 and 2024, the country’s corporate sector delivered a string of unexpected wins that challenged long-held assumptions. Inflation—once elusive—finally took hold, accompanied by steady wage growth. Rather than hurting margins, this shift allowed companies to pass rising costs onto consumers, driving strong revenue gains across key sectors.
This renewed economic vitality was reflected in the markets, with the Tokyo Stock Exchange experiencing its most bullish run since the asset bubble burst—lifting valuations and drawing global investor attention. That confidence extended beyond the country’s borders: foreign direct investment reached a historic high of ¥50.5 trillion in 2023, as global capital flowed into Japan’s economy, spanning sectors from advanced manufacturing to digital services.
At the same time, more Japanese companies began accelerating their international expansion—seeking growth opportunities abroad through cross-border deals, overseas partnerships, and global brand-building efforts.
The transformation wasn’t limited to listed giants. As corporations and venture capital firms poured investments into areas like AI, smart logistics, e-commerce, and clean energy, Japan’s start-up ecosystem reached record levels, with valuations and launch activity accelerating after a decade of steady growth.
Had global analysts and media predicted this evolution ten years ago, it would have sounded far-fetched. The dominant view was that Japan’s corporate landscape was plagued by inefficiencies, risk aversion, and a lack of speed.
The Weight of Tradition: When Strength Becomes Restraint
To understand the reasons behind this evolution, it’s essential to examine the deep-rooted structural challenges that have historically limited Japanese businesses.
For decades, Japan’s corporate culture favored stability over bold risk-taking—limiting engagement in M&A and cross-border investment. The result was a highly fragmented business landscape, particularly among small and medium-sized enterprises (SMEs), which struggled to scale operations or compete globally. This fragmentation, combined with an inward-looking business culture, became a major obstacle to international expansion, just as growth prospects within Japan’s mature domestic market began to narrow due to the country’s rapidly shrinking population. The keiretsu cross-shareholding system, once seen as a source of internal cohesion, often came at the expense of external accountability—slowing efforts to restructure inefficient units or adapt quickly to market shifts. Together, these dynamics created structural barriers that limited Japanese firms’ ability to globalize and compete effectively on the world stage.
Another major obstacle was Japan’s lag in digital transformation. Despite its global leadership in robotics and precision engineering, many sectors—especially services, retail, and traditional back-office operations—fell behind in adopting AI, cloud computing, and automation. This uneven progress severely limited productivity gains and delayed the shift toward data-driven, responsive business models. Legacy systems, underinvestment in digital infrastructure, and cultural resistance to change compounded the issue. As a result, Japan risked falling behind in a global economy where speed, scalability, and digital agility are essential to competitiveness.
So what exactly happened?
Rewriting the Playbook: A New Corporate Philosophy Emerges
In recent years, Japan has seen a wave of policy reforms that are significantly changing the corporate landscape. The Corporate Governance Code, introduced in 2015 and revised in recent years, has strengthened oversight and shareholder accountability—today, 95% of listed companies have independent directors, compared to just 21% in 2014. These reforms, combined with recent pressure from the TSE to improve valuation, are leading to greater transparency and stronger governance standards–factors favored by global investors. At last, METI’s new guidelines for corporate takeovers are further promoting consolidation and the unwinding of cross-shareholding, pushing M&A activity to record highs for two consecutive years.
These changes are evident when looking at Japan’s corporate icons. Between 2017 and 2022, Hitachi undertook a significant restructuring, divesting over $18 billion worth of non-core businesses. This strategic shift allowed the company to streamline operations and concentrate on core areas such as digital and data analytics. As a result, Hitachi’s market value tripled to over $100 billion within two years, positioning it among Japan’s most valuable companies. Similarly, Takeda Pharmaceuticals exemplifies Japan’s corporate reform momentum. Once a family-led firm, it adopted global governance standards and executed a bold $62 billion acquisition of Shire in 2019. Today, over 70% of its revenue comes from international markets, reflecting the impact of strategic leadership and structural change.
Internationalization has also become a powerful response to past perceptions of Japan as overly inward-looking. Faced with a mature domestic market and the need to secure long-term growth, more Japanese firms are viewing global expansion not as a risk, but as a strategic necessity, marking a decisive shift in corporate philosophy.
This growing international outlook isn’t limited to large pharmaceutical or industrial players. A new generation of Japanese companies is proving that global success is within reach across industries. Mercari has built a strong U.S. presence with its mobile-first resale platform, while Frontier Management Inc. is guiding domestic firms through cross-border M&A as Japan’s influence in international finance expands. Meanwhile, Tokio Marine Holdings has executed a series of major overseas acquisitions, including U.S.-based HCC Insurance and Pure Group, to diversify its portfolio and reduce reliance on Japan’s mature insurance market. Today, more than half of its profits come from international operations, reflecting a deliberate long-term strategy to become a truly global insurer.
Additionally, Japan is accelerating its digital shift through a combination of government initiatives and strong corporate investment. Under the Society 5.0 initiative, the government has committed ¥1.2 trillion toward AI, quantum computing, and smart infrastructure. At the same time, corporate DX-related IT spending reached ¥3.12 trillion in FY2023, and is expected to more than double to ¥6.9 trillion by FY2028, reflecting rising demand across IT, marketing, and service sectors.
As a result of structural reforms and accelerating digital transformation, Japan is seeing the emergence of new companies, business models, and sectors. Efforts to modernize corporate governance and invest in advanced technologies have created a more supportive environment for innovation and entrepreneurship. This shift is fueling the growth of agile, tech-driven businesses like Sakana AI, which became a unicorn in 2024 after raising a total of ¥30 billion in funding to develop cutting-edge AI solutions aligned with Japan’s digital priorities. In parallel, companies like ZOZOTOWN, now one of Japan’s leading fashion e-commerce platforms hosting over 7,000 brands, have thrived by embracing data-driven marketing and seamless digital experiences. These examples underscore how Japan’s transformation is laying the foundation for a more dynamic and globally competitive business landscape.
While Japan’s corporate transformation is gaining momentum, challenges remain. The country’s ability to expand globally, accelerate digital adoption, and transform its corporate structure will determine whether it can redefine itself—not just as a manufacturing powerhouse, but as one of the most competitive hubs of the digital era.
