After Taking a Breather, Why Japan Stocks Could Keep Rising

Pulse Analysis

Japan’s stock market has demonstrated resilience, climbing nearly 10% year‑to‑date despite a volatile backdrop. The recent dip, driven by the Iran‑Israel war’s impact on LNG supplies and higher oil prices, has trimmed gains but not fundamentally altered the bullish narrative. Energy‑related cost pressures are expected to be short‑lived as OPEC plans to increase supply and the Strait of Hormuz remains largely open. This temporary setback underscores the market’s underlying strength and its capacity to absorb external shocks.

Policy dynamics are now the primary catalyst for future appreciation. The Liberal Democratic Party’s supermajority in the lower house clears legislative hurdles, enabling a more aggressive growth agenda that includes defense spending, AI and semiconductor investment, and strategic state support for national champions. Coupled with the Financial Services Agency’s push to unlock the massive cash hoard on corporate balance sheets, earnings margins are set to expand. Valuation metrics, while higher than historic lows, still compare favorably to the S&P 500 and MSCI ACWI, suggesting room for multiple expansion as investor sentiment improves.

From an investor standpoint, Japan remains under‑weighted in global portfolios, with large‑cap blend funds allocating just over 4% to the market. This scarcity, combined with solid earnings forecasts—forward profit margins nearing 9%—creates a compelling risk‑adjusted opportunity. Sectors poised for outperformance include AI‑enabled software, chipmaking, and consumer‑goods firms leveraging domestic reforms. While geopolitical tensions pose a short‑term headwind, the convergence of favorable policy, corporate governance upgrades, and modestly stretched valuations positions Japan for a sustained rally.
