Hitachi, Advantest ride AI boom to lead Japan Inc. profit bonanza
Hitachi and Advantest are leading Japan's technology sector on a surge of AI-driven demand. Both companies reported robust profit growth from rising orders for semiconductor manufacturing equipment and AI chip testing gear, positioning Japan Inc. for record earnings as global AI spending accelerates.

Japan's semiconductor and equipment manufacturers are capitalizing directly on surging global AI spending. Hitachi's industrial automation and control systems have seen robust demand, while Advantest's dominance in semiconductor testing equipment has made it a prime beneficiary of the AI chip manufacturing boom. Both companies reported earnings growth in the 50-100% range in Q1.
Japanese tech firms are aggressively expanding capacity to meet the wave of orders from chipmakers like TSMC and Samsung ramping production for AI applications. Advantest and Hitachi are investing heavily in new test and manufacturing lines, signalling confidence that AI demand will sustain well into 2027. The Nikkei 225 has climbed to record highs partly on these earnings surprises.
However, this profit bonanza carries geopolitical risk. The Middle East war has pushed oil prices above $125 per barrel, and energy-intensive semiconductor manufacturing is vulnerable to sustained high energy costs. Japan's reliance on imported energy means that prolonged oil shocks could compress margins and cap the upside on this earnings boom.
