Japan’s stock market has achieved remarkable growth, culminating in the Nikkei 225 index reaching an all-time high in January 2026. This resurgence marks an impressive turnaround from the economic stagnation that plagued the country during the past few decades following the 1989 stock market crash. Over the last five years, the Tokyo Stock Price Index (TOPIX) has surged by 93.3%, while the Nikkei 225 has risen by 84.3%. In comparison, the S&P 500 index has seen an increase of 79.2% over the same period.
At the heart of this positive market performance lies a significant transformation in corporate governance practices in Japan. While descriptions of corporate governance might lack the flair of hot product launches or prominent CEO changes, these behind-the-scenes adjustments have played a crucial role in revitalizing investor sentiment and delivering substantial returns.
Historically, major Japanese corporations have operated within the confines of the “keiretsu system,” characterized by knitted partnerships and mutual shareholding among companies. This approach fostered a sense of stability but often resulted in inefficiency and a stifled willingness to adapt. Underperformance was sometimes shielded by cross shareholdings, which protected complacent management and impeded competitive growth. As a result, shareholder returns often took a backseat in the corporate agenda.
However, recent reforms initiated by Japan’s Financial Supervision Agency (FSA) and the Tokyo Stock Exchange have aimed to dismantle this outdated structure. The reforms have actively discouraged the longstanding practice of cross shareholdings, pushing companies to prioritize shareholder value. Research from J.P. Morgan indicates that since fiscal year 2020, Japanese firms have increasingly liquidated these inter-company shareholdings.
Moreover, starting in 2023, the Tokyo Stock Exchange has begun publicizing lists of companies that exhibit improvements in capital efficiency. This initiative promotes the adoption of best practices and urges firms to raise their awareness regarding stock prices and the cost of capital.
These reforms are fundamentally reshaping Japan’s corporate landscape. More Japanese firms are now incentivized to adopt aggressive strategies aimed at boosting competitiveness. The focus has shifted to practices such as stock buybacks, divesting non-core operations, and enhancing overall operational efficiency—all of which positively impact investor confidence.
For international investors looking to capitalize on this upward trajectory, the iShares MSCI Japan ETF presents a compelling opportunity. This exchange-traded fund, which tracks 181 of Japan’s leading companies, has outperformed the S&P 500 over the past year, boasting a 25.9% gain compared to the S&P’s 13.7%. Notable holdings in the ETF include globally recognized brands like Toyota and Sony, as well as key players in various sectors, including industrial giants Hitachi and Mitsubishi, and major financial institutions like Sumitomo Mitsui Financial Group, Mizuho Financial Group, and Mitsubishi UFJ Financial Group. The fund maintains an expense ratio of 0.49%, making it an attractive option for investors aiming to diversify their portfolios with Japanese assets.
As Japan continues to embrace a more competitive and investor-friendly corporate culture, the potential for lucrative returns appears increasingly promising. Investing in vehicles like the iShares MSCI Japan ETF could prove to be a wise decision for those keen on capturing the growth of one of Asia’s most dynamic economies in 2026.
