TOKYO — Discontent over the persistently weak yen is spreading across corporate Japan to a group that has rarely spoken out — multinational industrial firms with substantial dollar revenues that, in theory, should welcome a softer currency. During the Gastech energy conference in Tokyo this week, executives from some of Japan's largest manufacturing and trading houses broke with customary restraint to warn that the yen's multi-decade lows are eroding the value of their overseas earnings and threatening domestic investment.
The remarks represent a rare public intervention by Japan's corporate elite, who have traditionally avoided direct commentary on exchange rate policy. The yen has fallen more than 10 percent against the dollar so far this year, breaching the 155 level in late July before the Ministry of Finance intervened with verbal warnings and dollar purchases. Since then, the currency has remained volatile, trading around 143 to the dollar in recent sessions.
'We understand the benefits of a competitive exchange rate, but the current level is no longer sustainable for our business planning,' said a senior executive at a major Japanese trading house, speaking on condition of anonymity. 'We are seeing the value of our dollar revenues decline month by month, and this is forcing us to reconsider capital allocation and hiring plans in Japan.'
The pushback comes as Japan's economy ministry and the Bank of Japan face increasing pressure to address the yen's decline. Governor Kazuo Ueda has maintained that monetary policy decisions are made independently, while Finance Minister Shunichi Suzuki has said the government is monitoring currency moves 'with a sense of urgency.' The Ministry of Finance declined to comment specifically on the corporate statements but reiterated its commitment to taking appropriate action when market moves become one-sided.
Economists say the unusual corporate commentary highlights the growing strain of the yen's decline. While a weak currency typically boosts the earnings of exporters such as Toyota and Sony by converting overseas profits into more yen, the current situation is different. Many of Japan's largest firms have shifted production overseas and rely heavily on dollar-denominated supply chains, meaning a falling yen increases their input costs even as it lifts export revenue.
'The traditional model no longer applies the way it used to,' said Hiroshi Sato, senior economist at Daiwa Securities. 'These firms have globalized their operations, and the yen's decline is hitting them on both sides — higher dollar costs for parts and materials, and lower yen value for their overseas sales.'
The corporate statements have also reignited debate over whether the Bank of Japan should adjust its ultra-loose monetary policy. Some analysts argue that faster policy normalization could help stabilize the currency, while others warn that premature tightening could dampen Japan's fragile post-pandemic recovery. The central bank's next policy meeting is scheduled for September, where the yen's trajectory is expected to feature prominently in discussions.
In a sign of the breadth of concern, several keiretsu-affiliated firms have reportedly begun internal reviews of their hedging strategies and foreign currency exposure. While Japanese companies have long used financial instruments to mitigate exchange rate risk, the current volatility is forcing a reassessment of those strategies.
The government's response remains uncertain. Suzuki has declined to rule out further verbal intervention, and market watchers say the Ministry of Finance may be preparing to coordinate with the Bank of Japan on a more coordinated approach. For now, Japan's corporate sector is sending a clear message: the yen's decline has gone too far.
'We are not asking for a strong yen at any cost,' the trading house executive said. 'But we need a level that allows us to plan for the future without constant currency uncertainty. That level has clearly been breached.'
