The Nikkei 225 rose 1% to around 40,200, while the broader Topix Index gained 0.9% to 2,860 in post-holiday trading on Tuesday, extending last week’s gains as investors digested the weekend’s election outcome. Although Japan’s ruling coalition lost its majority in the upper house, the result was largely anticipated by markets. Importantly, Prime Minister Shigeru Ishiba is expected to remain in office, easing fears of political instability or a sudden resignation. Ishiba reaffirmed his commitment to stay on, citing the need to manage ongoing tariff negotiations with the US and other key policy matters. Top gainers included SoftBank Group (4.9%), Fujikura (4.3%), Mitsubishi Heavy Industries (5.5%), Advantest (2.2%), and Mitsubishi UFJ Financial (1.7%).
