TOKYO, Nov 15 (Reuters) - The Bank of Japan on Wednesday reduced offer amounts for its regular buying of Japanese government bonds, as the 10-year government bond yield fell to its lowest level in a month.

The BOJ offered to buy 575 billion yen of 5-10 year bonds, compared with 675 billion yen in previous offers.
