The Nikkei 225 Index edged up 0.05% to close at 53,359, while the broader Topix Index fell 0.79% to 3,535 on Wednesday, with Japanese equities delivering mixed performances as a sharply strengthening yen continued to weigh on the market. The yen has gained about 4% over the past three sessions amid growing speculation over a potential joint US-Japan currency intervention, while the dollar remained under pressure after US President Donald Trump said he was not concerned about its recent decline. Losses were led by export-oriented stocks, including Toyota Motor (-3.2%), Mitsubishi Heavy Industries (-2.6%) and Sony Group (-2.5%). In contrast, technology shares advanced, supported by overnight gains in US megacaps ahead of a heavy slate of major tech earnings. In corporate news, SoftBank Group jumped 3.7% after announcing it was in talks to invest an additional $30 billion in OpenAI.
