Ishiba’s resignation from the LDP and as prime minister immediately impacted the economy. Hours following the announcement, the Nikkei stock average rose by over 1.0%, and the yen depreciated against the US dollar.
This economic shift is a significant boon for Japan’s export-oriented sectors. A weaker yen makes Japanese products more price-competitive globally, directly boosting sales and profitability for internationally-focused companies. This especially benefits sectors with strong global reputations for quality and innovation.
Ishiba’s Resignation: Which Industries Benefits?
Automotive

Japan’s automotive industry is a cornerstone of its economy and directly benefits from a weaker yen. Major automakers like Toyota and Honda have extensive international sales networks. A depreciated yen lowers car and parts prices for foreign buyers, giving them a competitive edge against US and European rivals—compounded by the positive image of high-tech, innovative Japanese cars.
This currency advantage boosts export volumes and increases the value of overseas earnings when converted back to yen, enhancing profit margins. This can fuel further investment in R&D, particularly for electric vehicles crucial to countries working toward Net Zero goals.
Technology & Electronics

Companies like Sony, along with semiconductor and component manufacturers, have strong global presence. Their products—from consumer electronics to advanced industrial components—are known for precision and quality.
A weaker yen enhances their price competitiveness, making Japanese-made technology more attractive to international clients. Companies can either gain market share by lowering prices or increase profit margins by keeping prices stable, strengthening their financial position and ability to innovate in a highly competitive global market.
Machinery

Japan is a world leader in high-quality industrial machinery, robotics, and machine tools essential for manufacturing worldwide. While Japanese machinery is already sought after for reliability and technological sophistication, a weaker yen makes these capital goods more affordable for international businesses.
This price advantage can stimulate demand and lead to surging export orders, allowing companies to expand their international footprint and solidify their position as industrial technology leaders. This is especially impactful in B2B contexts, where large-scale capital investments are highly sensitive to price fluctuations.
Conclusion
Shigeru Ishiba’s resignation has created a significant shift in Japan’s economic outlook, particularly for export-driven industries. This dynamic underscores how political developments can directly and powerfully impact the B2B landscape, making it essential for businesses to stay informed and adapt their strategies.
