What did the UK files reveal about Junichiro Koizumi?

They show Junichiro Koizumi told Kim Jong Il in 2002 that North Korea could not defeat the US and UK, and he urged engagement. In 2004, he warned that even regime collapse might not bring stability. For markets, this confirms Japan’s pragmatic, cautious approach to regional security risk.

How could this affect Japan’s stock market in 2026?

We expect recurring headline risk but limited policy surprises. Short bursts of risk aversion can hit cyclicals, while domestic defensives may hold better. The yen often firms on security scares. Use hedges, keep cash for tactical buys, and reassess after official statements on drills, sanctions, or talks.

Does this change Japan’s diplomacy toward North Korea?

Not materially. The files reinforce an existing pattern: deterrence with room for dialogue. That likely means steady coordination with allies and careful messaging. Investors should watch for any restart of multilateral North Korea nuclear talks and confirm progress through concrete steps before shifting portfolio risk.

What should currency traders watch now?

Focus on official alerts, missile or satellite test windows, and statements from Japan’s cabinet and allies. Short-term shocks can lift JPY, but follow-through depends on policy actions. Set levels for hedge adds, and fade overreactions when diplomacy resumes or risk events pass without escalation.
