Japan remains on high alert over foreign exchange movements, its top currency diplomat Atsushi Mimura said Thursday, following the yen's sharp rise against the dollar in the day's trading.
"I'm neither reassured nor satisfied" with the yen's current levels in the currency market, he told reporters, adding, "I think we need to remain on a war footing."
The dollar slipped to the lower 156 yen range in Tokyo as market players expect the Bank of Japan to raise its key interest rate at the Sept. 17-18 policy meeting.
