The Japanese economy is currently exhibiting a perplexing phenomenon: while the real economy appears to be struggling, the stock market is surging forward with impressive momentum. From early 2023 to February 2024, Japanese stocks have experienced a remarkable rise of nearly 50%, approaching the peak levels unseen in almost three decades. This dichotomy between the stock market performance and the state of the underlying economy raises questions about the factors driving this notable shift.

One primary reason for this upward trend is the weak yen. For American investors, a depreciated yen makes Japanese stocks more affordable, enticing foreign capital into the market. The general consensus is that a yen drop to around 150 is seen as a floor, with expectations that the central bank might intervene should it decline further. Investing in Japanese stocks at this point not only bets on the rise of the yen but also on the stock market itself, creating a dual positive outlook that has significantly fueled the recent bull run in the stock market.

Furthermore, the restructuring of supply chains has played a crucial role in this phenomenon. Post-pandemic geopolitical shifts have necessitated a global reconfiguration of supply chains, positioning Japan—an export powerhouse—to reap substantial benefits. Higher-value-added supply chains are increasingly relocating to Japan, leading to a remarkable doubling of values in areas such as the semiconductor sector within a year. While the weak yen has spurred exports, particularly in industries like automobiles, these factors alone are not the sole drivers behind the stock market's drastic increase.

A critical element contributing to the bullish sentiment in the stock market is corporate reform. Historically, Japanese companies have emphasized stability over shareholder value, often refraining from dividends and layoff initiatives. This resulted in the emergence of many so-called "zombie companies" and inefficient processes within firms, contributing to low stock valuations—many companies have price-to-book ratios below one. A low price-to-book ratio indicates that the firm’s stock price lags behind its net asset value. This has traditionally deterred investors, perceiving these companies as unprofitable and undeserving of investment. As a result, Japan's stock market has garnered a reputation as a "value valley."

In 2022, Japan took steps to address this issue by introducing reforms that mandated listed companies with price-to-book ratios below one to undertake comprehensive restructuring, including initiating dividends and cost-cutting measures. Firms that fail to address these concerns by 2026 could face forced delisting. This has led to many Japanese companies increasing stock buybacks and dividends even amid the pandemic's pressures, a trend that promises to continue. The emergence of profitability and a commitment to profit distribution among shareholders have become key catalysts for the stock market's dramatic rise.

Additionally, the involvement of influential figures like Warren Buffett has played a pivotal role in the stock surge. Observing potential in Japan, Buffett invested approximately $60 billion into Japanese stocks three years ago, focusing on financial institutions. Last year, at 93 years old, Buffett personally visited Japan to encourage companies to boost their dividends and also increased his stakes in five major Japanese trading houses, sending a clear signal to the market. While it is challenging to quantify his impact precisely, since his investment, the Japanese stock market has experienced an impressive rise of nearly 40%.

However, the current landscape of the Japanese economy is rife with contradictions. The economic environment is marked by numerous conflicting signals, creating a complex scenario that requires careful analysis. While inflation—an element long awaited—has arrived, it is predominantly of the unwelcome imported variety. The central bank finds itself in a difficult position regarding interest rate controls, where a declining exchange rate aids exports but simultaneously causes capital outflows. Commonly accessed goods have inflated while wages stagnate, painting a grim picture of the real economy against the backdrop of a booming stock market.

Looking ahead to 2024, the World Bank predicts a modest GDP growth of 0.9% for Japan. However, the focus of the market seems to be less on GDP numbers and more on the broader economic implications. The upcoming year symbolizes a critical juncture for Japan: the challenge will be whether it can escape the long shadow of deflation and successfully transition its monetary policy back to a more normal state. This requires a gradual tapering of the central bank's extensive asset purchases while ensuring the government maintains a prudent approach to borrowing, all while facilitating stable economic growth without inducing systemic risks.

Recently, several major banks in Japan have taken the initiative to boost the rate on 10-year deposits significantly from a mere 0.002% to a more enticing 0.2%. This adjustment is expected to have lasting and far-reaching implications on the savings, investment, and consumption behaviors of the Japanese populace. The trajectory of Japan's economy is fraught with uncertainty, and the future will undoubtedly test the resilience and adaptability of its financial and corporate landscapes. As the nation navigates through these turbulent waters, observers around the globe will be watching closely to discern the outcomes of these pivotal developments.
