Japanese Prime Minister Yoshihiko Noda told The Wall Street Journal that all options were on the table for dealing with the strong yen, but stopped short of saying that the currency was overvalued. When asked about market views that Japan was unlikely to intervene against the yen's rise without support from the United States, Noda told the paper on Saturday that all options were open.
"There were times when we received co-operation," Noda said, speaking of the Group of Seven intervention after Japan's devastating earthquake last year. "But there were times when we acted alone. There can be various approaches."
Noda said officials were closely watching the yen's recent rise and said it was important to monitor whether the move was driven by speculative moves.
