latecomer japan eyes slice of rising global defence spending

Japan's policy shift opens a new supply source for global defense procurement, potentially increasing competition and supply chain options for importing countries. Japanese firms like Mitsubishi Heavy Industries and Kawasaki Heavy Industries gain access to a larger addressable market, but near-term revenue impact is limited by production capacity constraints. The channel is regulatory (export ban lifted) with a demand_spike from rising global defense budgets. Impact is global but initially concentrated on countries with defense cooperation agreements with Japan.
