Reducing the USD/JPY to 105 yen may cause the Bank of Japan to conduct intervention

Finance Minister of Japan Taro Aso said that the movement of the USD/JPY with five figures for two sessions are considered "one-sided" and that Japan does not intend to devalue the national currency "strong" or "long."
In his view it would be better if the pair stabilizes around 109.00 yen. This probably means that the reduction in the level of 105.00 may provoke intervention and these considerations probably at some point will chill the passions of the bulls in the Japanese currency.
On Tuesday morning the yen tried to rise against the dollar as investors avoided risk in lower expectations for Japanese intervention. The US currency rose to its three weeks peak at 110.59 amid prospects, that the Federal Reserve to raise interest rates in June.

USA noted that the dynamics of the yen is considered row, while Finance Minister Taro Aso continues to insist that the movement of the yen in recent months is "one-sided and speculative."
Aso also said that Japan has no intention to weaken further exchange rate to improve competitiveness.
