The Japanese yen fell to approximately 162 yen per U.S. dollar on Wednesday, marking its weakest level in about 39.5 years [1, 2].

This currency slide threatens to increase the cost of imported goods and energy, potentially stifling domestic consumption and placing a heavier financial burden on Japanese households.

Finance Minister Katayama Satsuki said the government will take appropriate action whenever necessary to address the exchange rate. The move comes as the yen continues to struggle against the dollar, far exceeding the 2025 average exchange rate of 149.7 yen [4].

Business leaders have expressed growing alarm over the volatility. Kobayashi Ken, president of the Japan Chamber of Commerce and Industry, said the depreciation is excessive. He said the situation has become critical because oil-driven inflation is expected to rise further [2].

The impact on the average citizen is already measurable. Data indicates that yen depreciation has resulted in an average extra cost of 15,534 yen per year for households [3]. This trend is particularly concerning as the currency moves past previous benchmarks, such as the 159 yen level reported in earlier periods [5].

Market participants are monitoring whether the government will intervene directly in the foreign exchange market to stabilize the currency. The combination of global economic pressures and domestic inflation has created a precarious environment for the yen, a trend that business groups warn could lead to further economic instability if left unchecked.

“The Japanese yen fell to approximately 162 yen per US dollar... marking its weakest level in about 39.5 years.”

The slide of the yen to a nearly 40-year low creates a double-edged sword for the Japanese economy. While a weak yen typically benefits large exporters by making their goods cheaper abroad, the current level of depreciation is driving 'cost-push' inflation. This means the rising cost of imports, particularly energy and food, is eroding the purchasing power of consumers, which may force the government to either intervene in currency markets or adjust monetary policy to prevent a broader economic slowdown.
