Japan Shares Climb Most in a Year on Iran War-End Hopes, Tankan

Japanese shares scored their biggest gain since April 2025 after Donald Trump said the US aims to end its war with Iran within three weeks, boosting sentiment. Strong results from the key Tankan business survey also fueled equities.

The Nikkei 225 gained 5.2% to close at 53,739.68 while the broader Topix climbed 5% to 3,670.90, marking the steepest daily rise for both benchmarks since April 10. Wednesday’s rebound came after the gauges recorded their worst monthly performance in 18 years in March.
