At the top, automotive giants and electronics leaders continue to dominate, with Toyota, Canon, Mitsubishi and Panasonic anchoring the list. Together, they underscore Japan\u2019s traditional strengths in mobility, imaging and semiconductors sectors that remain the backbone of the nation\u2019s innovation economy.<\/p>\n\n\n\n<p>Adding a fresh layer to this picture are three start-ups. KIOXIA Corporation, signalling Japan\u2019s determination to remain central to the global semiconductor supply chain. Prime Planet Energy & Solutions, the Toyota\u2013Panasonic joint venture, accelerated filings in battery technology, echoing Japan\u2019s national ambition to lead the electrification wave. And PayPay Co. Ltd., a fintech rising star, made its presence felt by carving out space in a list traditionally dominated by industrial titans.<\/p>\n\n\n\n<p>Behind every breakthrough in Japan, there\u2019s an inventor making it happen.
