Japan Morning Briefing: What to Watch on August 28, 2026

Tokyo investors face a mixed backdrop as Friday’s session opens, with overnight Wall Street gains offset by escalating Middle East tensions and a strengthening yen that threatens export competitiveness. The USD/JPY at ¥159.23 remains near multi-decade highs, providing a crucial tailwind for Japan’s export giants even as geopolitical risks cloud the global outlook.

Wall Street Rally Driven by Tech Earnings Optimism

U.S. markets closed higher Thursday, with the Nasdaq 100 leading gains at +1.37% to $721.11, while the S&P 500 added 0.66% to $771.10. The Dow Jones managed a modest 0.19% gain to $534.22. Jim Cramer’s commentary on CNBC highlighted how strong Nvidia and Salesforce earnings have challenged bearish narratives around AI spending, potentially benefiting Japanese tech suppliers like Tokyo Electron and Shin-Etsu Chemical.

Yen Weakness Supports Exporters Amid Iran Tensions

The USD/JPY holding above ¥159 continues to favor Japanese exporters, with Toyota, Sony, and Nintendo likely to benefit from favorable translation effects. However, Iran’s conditions for reopening the Strait of Hormuz and reports of Trump meeting with energy sector leaders ahead of midterm elections underscore rising oil price pressures that could squeeze domestic consumption.

Key Themes for Tokyo Trading

Watch for sector rotation into defensive plays as geopolitical risks mount, while export-heavy names may extend gains on yen weakness. Apple’s upcoming September event could impact Japanese suppliers in the iPhone supply chain. NISA investors should monitor energy-sensitive sectors like airlines and retailers, which face headwinds from potential fuel cost increases. The interplay between tech optimism and Middle East tensions will likely drive intraday volatility across the Nikkei 225.
