# From Sony to Muji, Japan's Multinationals Cash In on the Feeble Yen > This earnings season has handed Japan's global champions a familiar gift. With the yen slumping past levels most companies had cautiously assumed, exporters and retailers alike are raising their forecasts, led by a Sony profit that jumped by nearly a third. The windfall is real, and so are the risks of leaning on it. - Source: Morning Sun - Canonical URL: https://morningsun.jpn.com/article/from-sony-to-muji-japan-s-multinationals-cash-in-on-the-feeble-yen - Author: Morning Sun Editorial - Section: Business - Published: 2026-08-10T07:36:01.629Z - Updated: 2026-08-10T07:36:01.629Z - Tags: Weak Yen, Sony, Toyota, Muji, Ryohin Keikaku, Japan, Earnings, Multinationals --- Earnings season in Japan has taken on the feel of a victory lap for the country's biggest global companies. One after another, the giants that sell their goods and services around the world have stepped up to report stronger profits and to lift their outlooks for the year, and one factor keeps recurring in their explanations. The yen is weak, and a weak yen is money in the bank for any Japanese firm that earns much of its living abroad. The gains have not been confined to a single corner of the economy. From the carmakers to the electronics and entertainment groups to the retailers behind familiar high-street brands, the benefit has spread across sectors that at first glance have little in common. What unites them is exposure to foreign revenue, and this quarter that exposure has paid off handsomely as overseas earnings converted back into a soft home currency at a flattering rate. ## A quarter of upgrades The clearest example came from Sony, whose quarterly profit leapt by around a third, a jump that reflected both healthy demand for its products and content and the currency tailwind blowing behind it. It was far from alone. Company after company used the reporting period to nudge full-year profit targets higher, a wave of upgrades that turned what might have been a routine season into a notably upbeat one for shareholders. Retailers joined the exporters in the winners' column. Brands that sell globally, including the minimalist household name Muji, have found the weak yen amplifying their overseas takings, while at home the same cheap currency has drawn waves of foreign tourists whose spending flows straight into Japanese tills. For businesses spanning both channels, the currency has been a double blessing, lifting the value of foreign sales and importing shoppers at the same time. ## Beating their own cautious math Part of what makes this season look so strong is the gap between what companies expected and what actually happened. When Japanese firms build their forecasts, they pencil in an assumed exchange rate, and this year most set that assumption conservatively, planning around a yen worth roughly 154 to the dollar. The real rate has been considerably weaker than that, slipping past 160 and beyond, which means reality handed the companies a currency even more favorable than the one they had modeled. That conservatism is exactly why the upgrades came. Every yen of weakness beyond a company's assumed rate drops almost directly onto its profit line, so when the actual currency undershoots the plan, the result is a stream of pleasant surprises and raised targets. The pattern rewards firms for having been cautious, but it also flatters their performance in a way that has little to do with selling more or running better. The easiest profit a Japanese exporter can make is the profit that appears simply because the yen fell further than the accountants assumed. ## A gift with a catch For all the celebration, executives know this kind of profit is fragile. A windfall created by the exchange rate can be undone by the exchange rate, and if the yen were to strengthen, the very same mechanism that inflated this quarter's earnings would just as briskly deflate the next. Building expectations on a currency that no company controls leaves those companies exposed to a reversal they cannot predict or prevent. There is a national dimension to the discomfort as well. The weak yen that enriches the exporters also raises the cost of everything Japan imports, from fuel to food, squeezing households and the many domestic-focused businesses that buy in foreign currencies and sell at home. The corporate earnings headlines glow, but they sit awkwardly alongside a cost-of-living strain that the same currency weakness helps drive, a split that has become a defining tension of the Japanese economy. ## Enjoying it while it lasts None of this stops the multinationals from banking the gains, and they are right to. Strong global demand underpins much of the improvement, and the currency simply magnifies it, giving these companies the cash and confidence to invest, reward shareholders and press their advantages abroad. A favorable quarter is a favorable quarter, and Japan's exporters have earned the applause that comes with it. The wiser among them, though, will treat the windfall as borrowed time rather than a new baseline. The task now is to turn currency-driven profit into the durable kind, by winning customers and building products that would sell just as well if the yen were strong. As long as the currency cooperates, Japan's global champions will keep posting numbers like these. The real test comes on the day it stops. --- Originally published by Morning Sun.
