The broader Topix index, meanwhile, had managed a modest gain of 2.84 points, or 0.07%, to stand at 4,159.13. Within the Prime Market, the most significant gains were observed in iron and steel, as well as oil and coal product sectors, while nonferrous metals and metal product shares experienced notable declines. The yield on the benchmark 10-year Japanese government bond reached a peak of 2.965 percent, marking its highest level since October 1996.
