Japan may increase its purchases of bonds to finance Europe's debt crisis rescue fund, Chief Cabinet Secretary Osamu Fujimura said Wednesday.

Fujimura told reporters the government "would like to consider" buying more bonds from the European Financial Stability Facility to help stabilize the region.

Japan bought more than 20 percent of the fund's initial five-year, €5 billion ($6.6 billion) bonds in January, and purchased another €1.1 billion of 10-year EFSF bonds issued in June.
