Japan Reappoints FX Chief Mimura Amid Tariff Talks and Yen Concerns

Japan has reappointed Atsushi Mimura as vice finance minister for international affairs, solidifying his leadership over foreign exchange policy during critical U.S. tariff negotiations. The reappointment, announced by the finance ministry on Tuesday, is effective July 1 and marks Mimura’s second year in the role.

Finance Minister Katsunobu Kato cited Mimura’s experience and current involvement in trade talks with Washington, including dialogue with U.S. Treasury Secretary Scott Bessent, as key reasons for his continued tenure. Mimura, 58, oversees Japan’s currency strategy and international economic coordination.

His reappointment signals continuity as Japan navigates a fragile economic landscape shaped by a weak yen. Though the Japanese currency has rebounded slightly to around 145 per dollar—up from a 38-year low of 161.96 last year—it continues to pressure policymakers by raising import-driven inflation.

Unlike his predecessor Masato Kanda, who served three years and led historic currency interventions, Mimura is known for his minimalist communication style. During last November’s sharp yen drop past 150, he escalated warnings from “high urgency” to “utmost urgency,” signaling heightened concern without overt action.

Mimura believes strategic silence can also be a form of guidance. “Being always vocal is one style of communication, but not speaking may also be another,” he told Reuters, underscoring a careful balance to avoid fueling market speculation.

While Japan’s finance ministry typically rotates personnel annually, extended terms are common for senior FX officials due to the complex nature of global monetary coordination. Mimura’s steady leadership is seen as critical as Japan balances inflation risks, currency stability, and trade diplomacy with the U.S. in 2025.
