- The investment case for Japan rests on corporate governance reforms, not monetary policy, currency movements or economic activity.
- As companies unwind corporate cross-shareholdings, we see opportunities for ample value creation for investors.
- Lower correlations with other international stock markets, and limited analyst coverage makes Japan an attractive portfolio diversifier and a market where active management can thrive.
For decades, corporate Japan was defined by stagnation—low growth, entrenched management teams and idle capital on balance sheets. Today, that landscape looks markedly different. Corporate reform, rising merger and acquisition (M&A) activity, reflationary dynamics and a steady shift of household assets from savings into investment are reshaping both corporate behaviour and market opportunities.
Yet investor allocations have been slower to adjust. Many portfolios still access Japan incidentally, as part of a broad international mandate, rather than through a dedicated allocation, often limiting the ability of specialist active managers to fully exploit the breadth of opportunities emerging from these structural changes. In our view, this overlooks one of the most significant corporate transformations underway in global equity markets, and a valuable opportunity to strengthen portfolio diversification.
Why the Japan opportunity has changed
The investment case for Japan today is fundamentally different from previous cycles. Historically, many investors focused on monetary policy, currency movements or economic growth. Today, boardroom changes are the more important story.
Since the launch of Abenomics, Japanese companies have delivered stronger cumulative earnings-per-share growth than their U.S. counterparts despite Japan’s relatively modest economic growth. This earnings strength reflects structural improvements in profitability, capital allocation and management discipline rather than favourable macroeconomic conditions alone.

Corporate governance reform is at the heart of this change. The Tokyo Stock Exchange’s (TSE’s) focus on capital efficiency, combined with increasing shareholder engagement, is encouraging companies to improve returns on equity, simplify corporate structures and allocate capital more effectively. As a result, dividend growth and share buybacks have reached record levels, while companies are becoming more willing to divest non-core assets, restructure businesses and pursue strategic M&A.
Importantly, this reform story is far from complete. Despite meaningful progress, Japanese corporates continue to hold cash balances exceeding 40% of gross domestic product (GDP), more than double U.S. levels.
One of the clearest manifestations of Japan’s corporate governance reforms has been the accelerating unwinding of cross-shareholdings. For decades, Japanese companies accumulated large portfolios of shares in other companies, often generating profits without meaningfully returning capital to shareholders. Today, the TSE requires listed companies to justify these holdings based on both strategic relevance and economic returns, with companies unable to do so increasingly coming under pressure to explain why these assets remain on the balance sheet.
As scrutiny of capital efficiency intensifies, particularly among companies trading below book value, the pace of cross-shareholding disposals has accelerated. The opportunity remains substantial. Investment securities still represent around 13% of market capitalisation for the cheapest valuation quintile of Japanese equities, compared with just 0.5% for the most expensive. These lower-valued companies are also the most active sellers, with 77% reporting securities disposals in the most recent fiscal year and generating cash proceeds equivalent to 1.6% of aggregate market capitalisation. Proceeds from these disposals are typically reallocated across a combination of internal reinvestment, inorganic growth initiatives and the return of excess capital to shareholders.
Yet despite accelerating disposals, the cross-shareholding unwind could take another decade to complete at the current pace. Strategic shareholdings across the TOPIX still total approximately ¥53 trillion, or around 7% of market capitalisation. As excess cross-shareholdings are monetised and capital allocation becomes more disciplined, a significant portion of the potential shareholder value creation opportunity still lies ahead.

The scale of these excess balance-sheet resources helps explain why engagement-led value creation remains such a powerful theme today. Japan is now one of the world’s most active markets for shareholder engagement, private equity investment and M&A activity—with investors increasingly encouraging companies to unlock value through improved governance, portfolio rationalisation and more disciplined capital allocation. The sharp increase in M&A activity and transactions such as the proposed Toyota Industries buyout demonstrate that even long-established corporate structures are no longer immune to change.
Is Japan following America's value creation playbook?
What is unfolding in Japan today bears striking similarities to the U.S. in the early 1980s, a period that preceded one of the greatest wealth creation cycles in modern history. At that time, nearly 40% of U.S. equities traded below book value, corporate returns on equity languished in the mid-single digits and capital was trapped within sprawling conglomerates that faced mounting pressure to improve efficiency and shareholder returns. The response was a profound shift in corporate behaviour, driven by deregulation, restructuring, M&A activity and a renewed focus on capital discipline, laying the foundation for decades of value creation.

Japan is now undergoing a similar transformation. Governance reforms are encouraging companies to improve profitability, optimise balance sheets and prioritise shareholder returns, while a highly fragmented corporate landscape still offers significant scope for consolidation.

Japan also remains in the early stages of a retail investor revolution. Just as the introduction of 401(k)s and IRAs in the U.S. channelled household savings into equities, Japan’s expanded Nippon Individual Savings Account (NISA) programme is encouraging a generation of first-time investors to shift assets out of cash and into the stock market. Japanese households hold approximately $15 trillion of financial assets, a sum equivalent to more than four times France’s GDP, yet around half of this wealth remains in cash and deposits. The U.S. experience illustrates how household portfolios can evolve as savings gradually move towards investment, highlighting the potential scale of Japan’s long-term asset-reallocation opportunity.

Japan's role in international portfolios
While a country allocation may appear to increase concentration risk, portfolio risk is ultimately determined by how assets interact within the broader portfolio. Japanese equities have historically demonstrated low correlation with U.S. equities, especially technology-driven benchmarks. While some correlations exist, it remains materially lower than that of most major developed equity markets. The lower correlation is most pronounced in hedged Japanese equities and Japan small-and mid- (SMID) caps, suggesting that both currency and exposure beyond large caps can influence the role Japan plays in portfolio construction.

The structure of the market itself supports this differentiated behaviour. Japan provides exposure to a market with a distinct structure and sector composition. The ten largest S&P 500 companies account for roughly 38% of index capitalisation, near an all-time high. In Japan the top ten are closer to 23%. Sector exposures also differ meaningfully, with the Japanese market providing greater representation in financials, industrials and automobiles.

Importantly, investors are not required to pay a premium for these diversification benefits. Japanese equities trade at a meaningful discount to the U.S. on forward earnings, by most measures 15% to 20%. The diversification does not come at a premium.
The case for specialist active management
Returns in Japan are increasingly a function of stock selection, not market exposure. Japan is also one of the least efficiently researched developed markets in the world, with ~45% of the TOPIX not covered by any sell-side analyst.

Combined with wide dispersion in profitability, governance standards and capital allocation practices, this lack of coverage creates fertile conditions for skilled active managers to add value through stock selection. Evidence can be seen in the historical record, with the median Japan equity manager outperforming its benchmark across most trailing periods over the past decade.

However, manager selection is equally important. Successfully navigating this market requires a specialist team with deep experience and a repeatable investment process. We believe a quality-focused approach is particularly well positioned for Japan’s low-growth environment. By investing across both growth and value opportunities, investors can gain exposure to companies capable of delivering sustainable earnings growth, improving capital efficiency and long-term value creation.
The bottom line
The evolution of corporate Japan has outpaced investor allocations. Governance reform is driving capital discipline and higher shareholder returns. Earnings have compounded faster than in the U.S., built on structural change rather than macro tailwinds. The market offers diversification benefits through differentiated sector composition and correlation profile. And beneath all of it, inefficiency plays to the strengths of active management in a way passive exposure can’t replicate.
None of this stands out in a broad international sleeve. Diluted across a non-U.S. developed market or All Country World allocation, Japan becomes a rounding error – its correlation benefits, its distinct sector mix, its earnings trajectory are all averaged away rather than captured. Realising this opportunity means sizing Japan on its own terms and pairing it with the specialist, active management the market specifically rewards.
The reform is real, it’s unfinished and it’s investable. The question for allocators isn’t whether Japan belongs in a portfolio – it’s whether it belongs by design, or merely by accident.
