On September 8, 2022, the USD/JPY broke through 144 as the Japanese Ministry of Finance, central bank, and financial bureau held a joint meeting.
On September 14, the USD/JPY approached 145 as the Bank of Japan implemented a rate check, requiring major Japanese commercial banks to provide details of foreign exchange transactions to the central bank.
Subsequently, on September 22, the Japanese government and central bank conducted an intervention amounting to 2.8 trillion yen but failed to halt the depreciation of the yen.
After the yen breached the 150 level against the US dollar, on October 21 and 24, the Japanese authorities implemented interventions totaling 6.35 trillion yen. As the US dollar weakened, the yen started to appreciate.

Referring to last year's intervention process, which involves "government authorities' trilateral meeting → exchange rate review → foreign exchange intervention," the trilateral meeting has already been held at the end of May. Whether the exchange rate review will be implemented in the future is a concern for the market.
Based on the relevant statements, the Japanese authorities have a relatively high tolerance for the depreciation of the yen. The exchange rate review may be conducted when the yen depreciates to around 150, and foreign exchange intervention may occur if it depreciates beyond 150.
