Japan Surprises: Why the Nikkei Is Attracting Foreign Investors

The Sleeping Giant Awakens

The Nikkei 225 has surpassed its 1989 all-time high — a peak many thought would never be seen again. Japan, considered a "value trap" market for 30 years, has become Wall Street''s most consensus trade in 2026. And for good reason.

Three Structural Reasons

1. Governance Reform (Tokyo Stock Exchange)

The TSE launched a historic reform in 2023: companies trading below book value (P/B < 1) must publish improvement plans. Result: Japanese companies are restructuring, increasing dividends, launching buybacks and selling cross-shareholdings that paralyzed capital.

2. The Weak Yen

At 158 JPY/USD, the yen is at a 35-year low. For Japanese exporters (Toyota, Sony, Nintendo), it''s a massive competitive advantage: every dollar of sales generates more yen profit. Japanese automakers saw operating margins jump 3 points.

3. Flow Reallocation

Warren Buffett paved the way by investing in Japan''s 5 trading houses (Mitsubishi, Mitsui, etc.). Sovereign funds and hedge funds follow. Japan offers attractive valuations (14x P/E vs 22x for S&P 500) with 15%+ earnings growth.

The Risk Not to Ignore

The weak yen is a double-edged sword. If the Bank of Japan finally normalizes monetary policy (rate hikes), the yen would strengthen and exporters would suffer. For an unhedged European investor, a yen move from 158 to 140 means a +12% currency gain — but the stock market could drop 10% in response.

Key Takeaway

Japan is a 3-5 year conviction trade, not a 3-month momentum play. Governance reforms are irreversible, buybacks are structurally increasing, and valuations remain attractive vs US and Europe. Recommended allocation: 5-10% of a diversified portfolio via a Japan ETF.
