Japanese shares may see an uptick as a result of potential bargain-hunting activity following a significant drop in the benchmark index last Friday. However, any gains could be capped due to the back-and-forth attacks between the United States and Iran over the weekend, which are putting pressure on the fragile peace agreement between the two nations. On the Singapore Exchange, Nikkei index futures are up by 355 points, trading at 70,130. The Nikkei index closed at 69,360.88 on Friday, marking a 4.15% decline.
