Column: Maintaining high vigilance against resurgence of Japanese militarism

Researchers at the Institute of World History (CASS) warn of a renewed resurgence of Japanese militarism, tracing post-war rehabilitation of right-wing figures, constitutional reinterpretations under Shinzo Abe, the 2007 upgrade of the Defense Agency, the 2014 revision of arms-export rules and the 2015 Security Legislation as key drivers. The piece highlights domestic political shifts, efforts to revise wartime history education, increasing defense spending and nuclear-capability concerns, and recent hardline remarks on Taiwan—factors that elevate geopolitical risk in East Asia and could influence defense procurement, regional political risk premia and investor positioning in related sectors.

Analysis

Market structure: Rising Japanese right‑wing rhetoric and policy shifts point to a structurally higher defense capex cycle in Japan and allied markets — winners include global and Japanese defense primes (Lockheed LMT, RTX, Northrop NOC; Mitsubishi Heavy 7011.T, Kawasaki 7012.T) and suppliers of missiles, radar, shipbuilding and C4ISR; losers are Japanese domestic cyclicals (travel, leisure) and anything sensitive to regional trade disruption. Expect procurement lead‑times of 12–36 months, a 5–15% lift in orderbooks for defense OEMs in a stressed 1–3 year scenario, and upward pricing power for specialized inputs (rare earths, high‑end electronics).

Risk assessment: Tail risks include a Taiwan contingency (model probability 5–12% over 2 years) causing severe supply‑chain shocks and crude oil spikes (+10–30% short term) and a fiscal shock if Japan adds 0.5–1.5% of GDP in defense spending raising JGB yields by 10–40 bps. Short term (days–weeks) watch for sentiment and FX moves; medium (3–12 months) for budget legislation and arms export policy changes; long term (1–5 years) for structural supply‑chain re‑routing and sustained capex. Hidden dependency: US force posture and export controls; catalyst: Diet votes, PM statements, and bilateral US–Japan security agreements.

Trade implications: Tactical plays — overweight US defense ETFs (ITA) and selective long on Japanese defense primes (7011.T, 7012.T) with 2–3% portfolio allocations, funded by reducing cyclical Japan consumer/tourism exposure (nominally short EWJ‑heavy travel names or travel ETFs). Use 3–9 month call spreads on LMT/RTX to capture anticipated order flow and buy 3‑6 month put protection on EWJ if JPY depreciates >5% or 10y JGB >+25 bps. Rotate into energy (short spikes) and gold (hedge) if geopolitical tensions escalate.

Contrarian angles: Consensus may overstate immediate militarization — Japan’s high public debt (>250% of GDP) limits sustained deficit financing, so durability of procurement is uncertain; defense wins could be front‑loaded (12–24 months) then mean‑revert. Historical parallels: post‑Cold War rearmament waves produced 12–36 month equity rallies then consolidation — trade with stop limits: trim if defense order momentum falters or if JPY rallies >3% on safe‑haven flows. Unintended consequence: accelerated semiconductor/geopolitical de‑risking benefits ASML/TSMC suppliers, which is an underappreciated mid‑term alpha source.

Key Decisions for Investors

• Establish a 2–3% long position in ITA (iShares U.S. Aerospace & Defense ETF) and 1–2% long positions in LMT and RTX via 3–9 month call spreads (strike ~5–8% OTM) to capture procurement upside ahead of FY budget cycles; target 20–40% gross upside, stop at 15% loss.
• Buy 1–2% long exposure to Mitsubishi Heavy Industries (7011.T) and Kawasaki Heavy (7012.T) on Tokyo market dips of ≥5% within 3 months; take profits if consolidated order announcements do not appear within 9 months or if 10y JGB yield rises >40 bps.
• Short 1.5–2% exposure to Japan travel/leisure basket (select high‑beta constituents of EWJ) via puts or short ETF if JPY weakens >5% or if monthly inbound tourism revs miss expectations for two consecutive months; set a tight stop if defense budget approval is delayed beyond 90 days.
• Hedge geopolitical tail risk: buy 3–6 month GLD calls (10–15% OTM) equal to 0.5–1% portfolio notional and allocate 0.5% to Brent crude call spreads (3–6 month) if PLA/US naval exercises escalate; unwind if oil rises >20% or gold >15% from entry.
