The Nikkei 225 Index jumped 4.4% to climb above 55,700, while the broader Topix advanced 3.1% to 3,768 on Wednesday, with both benchmarks reaching their highest levels in over a month. The rally followed an agreement by the US, Iran, and Israel on a two-week ceasefire to facilitate negotiations on a potential deal to end the war.
US President Donald Trump postponed planned strikes on Iranian civilian infrastructure, describing the arrangement as a “double-sided ceasefire.” In turn, Iran agreed to reopen the Strait of Hormuz for two weeks, on the condition that all transit be coordinated with the Iranian Armed Forces.
At the same time, Japanese Prime Minister Sanae Takaichi is seeking separate talks with both US and Iranian leaders as part of broader efforts to secure peace and safeguard Japan’s energy supplies.
On the corporate front, notable gains were recorded in Furukawa Electric (up 12.4%), Advantest (9.4%), Disco Corp (6.8%), Tokyo Electron (8.4%), and JX Advanced Metals (12%).
