Office workers move quickly through the glass corridors surrounding the Tokyo Stock Exchange on a weekday morning in Tokyo’s Marunouchi district. Coffee cups, suits, the soft hum of elevators. This financial district carried a subtle sense of disappointment for decades—Japan’s market, which had once dominated the world, drifted through what economists kindly referred to as “the lost decades.”
However, the atmosphere has changed recently. The Nikkei 225 has risen to levels that few investors had anticipated, symbolically returning to territory last visited during Japan’s economic boom in the late 1980s. The change has become hard to ignore for international investors who previously ignored Japan. Not just small sums of money are returning to Tokyo.

In 2025 alone, foreign investors bought about ¥5.4 trillion worth of Japanese stocks. That number startled many analysts because it represented a dramatic jump compared with the previous year. It’s simple to understand why curiosity has returned when you stand close to the trading floor and watch screens flicker with well-known names like Toyota, Sony, and Mitsubishi.
A portion of the narrative starts with corporate reform. Japanese businesses were known for hoarding cash and putting stability ahead of shareholder returns for many years. Dividends and buybacks lagged behind Western markets, and balance sheets were frequently overflowing with unused capital. However, in recent years, something has changed.
In addition to naming companies that trade below book value and urging management to reconsider their approach, the Tokyo Stock Exchange has started subtly pressuring businesses to increase capital efficiency. Dividend payments and share buybacks have increased as a result. Japanese companies announced record buybacks of almost ¥15 trillion in fiscal 2024 alone.
As this develops, it appears that corporate Japan has moved into a new phase where profitability is prioritized over market share. That seems to appeal to investors. Inflation, which would have been concerning ten years ago, is another factor contributing to Japan’s comeback. Japan has struggled with persistent deflation, a gradual decline in prices that deterred investment and spending, for the majority of the last thirty years.
Prices are now gradually but steadily increasing once more. Wages are starting to follow. The subtle changes—convenience stores changing product labels, restaurants in Tokyo raising menu prices by a few yen—indicate a larger shift in economic psychology.
Perhaps Japan needed this cycle of reflation. After years of ultra-loose monetary policy, the Bank of Japan has started to gradually change its position. Although interest rates are still low by international standards, the change indicates that the nation’s economy is finally warming up.
Another factor has been politics. Many investors find comfort in Japan’s current leadership’s pro-growth stance. Economic reforms and large-scale stimulus plans aim to boost investment and productivity. Gains in recent months have been led by the financial and real estate sectors, which have responded particularly well.
The most intriguing shift, however, might be taking place within Japanese homes. In the past, Japanese families favored keeping their savings in cash. Instead of being in stocks or mutual funds, more than half of household assets were in bank accounts. During decades of low inflation, that cautious approach made sense.
However, inflation modifies behavior. Cash gradually loses purchasing power as prices rise. Households are being encouraged to move money from savings to investments through initiatives like the government’s expanded Nippon Individual Savings Account (NISA). The pattern is similar to what happened with retirement accounts like 401(k)s in the US decades ago.
There is a sense that a generational shift is taking place as younger Japanese investors enter the market. The story is becoming more complex due to corporate restructuring. As businesses streamline their operations and eliminate underperforming divisions, the number of mergers and acquisitions is rising. Among major economies, Japan has historically had one of the most dispersed corporate environments, with businesses frequently operating in several unrelated sectors.
Many businesses are now concentrating on their core competencies in order to increase productivity and profit margins. JX Advanced Metals, a business that produces specialized materials used in semiconductor manufacturing, is one example that is garnering attention. Its recent listing on the Tokyo Stock Exchange demonstrated Japan’s expanding contribution to the global technology industry’s supply of vital components.
One of Japan’s quiet advantages is its connection to advanced manufacturing, including robotics, precision machinery, and chips. Skeptics still exist, of course.
Japan’s population continues to age rapidly, a demographic challenge that will shape the economy for decades. Despite improvements, productivity growth still trails some of its Western counterparts. Additionally, investors who recall earlier surges of optimism regarding Japan continue to exercise caution. The memory of markets is long.
However, there is something different about the present. It’s difficult to ignore the renewed interest from international investors when strolling through Tokyo’s financial district in the evening, with neon signs reflecting off rain-soaked streets. Hedge funds are setting up shop. Japan-focused funds are once again being introduced by asset managers.
