The yen is trading near ¥160 to the dollar, the level at which Japan has intervened in recent years. It is back at the red line about a month since it was last propped up with massive official purchases.
In early morning trade on Wednesday, the currency hit ¥159.99 to the dollar and continued to change hands near those levels as Tokyo markets opened.
The Finance Ministry said last week that it spent a total of ¥11.73 trillion ($73 billion) to support the yen from April 28 to May 27. On April 30, the currency rapidly strengthened into the ¥155 range after crossing the ¥160 mark earlier in the day.
