TOKYO - Japan spent a record 15.4 trillion yen ($96 billion) over the past month in yen-buying operations to stem its home currency's slide in the market, including a joint intervention with U.S. authorities, the Finance Ministry said Friday.

The amount topped the previous monthly record of 11.73 trillion yen spent over three days in April and May this year, data covering the period from July 30 to Wednesday showed, and exceeded an earlier market estimate of around 11 trillion yen to 12 trillion yen.
