Japan

Japan’s 12-month probability of a new armed-conflict onset on its territory is 0.5%, a minimal risk. The country has strong state capacity, durable democratic institutions, advanced defence capabilities, and no recent history of civil war, insurgency, or coups. These factors support resilience, although Japan’s proximity to China, North Korea, and Russia leaves it exposed to possible interstate escalation.

Recent reporting shows diplomatic friction with Russia after a Sept. 3 victory anniversary unveiling in Khabarovsk of a statue depicting a Soviet soldier destroying a marker bearing Japan’s chrysanthemum crest. Prime Minister Sanae Takaichi demanded its removal. This is hostile symbolism and a bilateral irritant, but it is not an armed incident on Japanese territory. A Polymarket contract on a China–Japan military clash before 2027 is priced at 6.5%, with substantial volume, though its partial scope is broader than this country-level onset measure.

The largest uncertainty is whether a crisis involving China, North Korea, or Russia could overcome Japan’s deterrence and diplomatic safeguards. A confirmed cross-border attack, sustained armed intrusion, or organised domestic violence would raise risk most clearly; continued alliance coordination, crisis management, and the absence of attacks on Japan would support the minimal classification.
