Japan's Governance Reforms: What They Mean for Foreign Investors

For decades, Japanese companies had a reputation among foreign investors for hoarding cash, holding each other's shares, and paying limited attention to returns on capital. That reputation is changing, and the change is the result of deliberate policy.

A series of reforms, from governance codes to stock exchange rules to new takeover guidelines, has pushed listed companies to focus on capital efficiency and treat shareholders differently. For foreign investors, the effects reach beyond public equities into M&A, corporate venture capital and the startup ecosystem.

1. The Reforms in Brief

• Stewardship Code (2014). Encouraged institutional investors to engage actively with the companies they own.
• Corporate Governance Code (2015, revised since). Introduced expectations on independent directors, board effectiveness, cross-shareholdings and capital policy, on a comply-or-explain basis.
• Tokyo Stock Exchange restructuring (2022). Reorganised listed companies into Prime, Standard and Growth segments, with higher standards for the Prime market.
• Exchange request on capital efficiency (2023). Asked listed companies, particularly those trading below book value, to disclose and act on plans to improve cost of capital awareness and share price.
• Takeover guidelines (2023). Government guidelines set out how boards should consider acquisition proposals, including unsolicited ones, with a focus on shareholder interests.

2. What Has Changed in Practice

• More buybacks and dividends. Companies have returned significantly more capital to shareholders.
• Unwinding cross-shareholdings. Many companies are selling strategic stakes they held in each other, freeing capital and reducing entrenchment.
• More independent directors and more attention to board composition.
• A more active M&A market, including unsolicited bids that would once have been unthinkable, and more take-private transactions.
• More shareholder activism, from both domestic and international funds, with activists increasingly finding support from other institutions.

International attention followed. Warren Buffett's Berkshire Hathaway disclosing stakes in Japan's major trading houses in 2020 was widely seen as a signal, and the Nikkei index surpassed its 1989 record high in early 2024.

3. What It Means for Public Market Investors

• Engagement works better than before. Companies are more responsive to shareholder proposals on capital allocation.
• Value opportunities remain. Companies with large cash balances or trading below book value face pressure to act.
• Governance quality varies widely. Reform is uneven; diligence on board independence, capital policy and disclosure still matters.
• Currency affects returns. Yen movements can dominate the dollar return on Japanese equities.

4. What It Means for M&A and Private Capital

• More assets for sale. Conglomerates are divesting non-core divisions, creating carve-out opportunities for private equity.
• Take-private deals have increased as management teams and sponsors look to restructure away from public markets.
• Boards must consider serious bids. The takeover guidelines make it harder to reject proposals without explaining why doing so serves shareholders.

5. What It Means for Venture Investors and Founders

• Government support for startups. Japan announced a five-year startup development plan in 2022 aimed at substantially increasing investment in startups.
• Corporate venture capital is active. Many large Japanese companies run venture arms and seek partnerships with domestic and foreign startups. See our guide to how corporate venture capital shapes the startup ecosystem.
• M&A as an exit. Historically, Japanese startups relied heavily on small IPOs on the Growth market. More active corporate buyers are making acquisitions a more realistic exit.
• The IPO market has limits. Many Growth-market listings have been small with limited liquidity, and the exchange has been reviewing listing standards. Our guide to routes to public markets covers alternatives.

6. Risks to Keep in View

• Reform is uneven. Some companies have changed deeply; others comply on paper.
• Cultural and language barriers still affect deal processes and relationship building.
• Political and policy shifts could slow or redirect reform momentum.
• Valuations have risen, so some of the easiest opportunities have already been priced in.

Frequently Asked Questions

Why did Japan push for governance reform?

To improve corporate profitability and share prices, attract investment, and support economic growth after decades of weak returns on capital.

Are foreign investors welcome?

Generally yes, and international capital has been an explicit goal of the reforms. Certain sensitive sectors are subject to foreign investment screening.

Is Japan a good market for startup investment?

It is increasingly attractive, with government support, active corporate partners and a large domestic market. Exit depth and scaling beyond Japan remain the key questions to diligence.

How should foreign investors approach Japanese companies?

With patience and local expertise. Relationships, clear communication and an understanding of board dynamics still matter as much as financial analysis.

The Bottom Line

Japan's governance reforms have moved from policy to practice, changing how companies allocate capital, respond to shareholders and consider acquisitions. For foreign investors, that opens opportunities across public markets, private equity and venture, provided they diligence governance carefully and account for the reforms' uneven reach.
