TOKYO, July 31 (Reuters) - Japanese shares pared losses while the yen fell and yields on Japanese and U.S. bonds declined on Tuesday after the Bank of Japan made minor policy tweaks, staying away from making drastic changes to its accommodative policy.

The Nikkei turned positive while the dollar gained 0.25 percent against the yen to 111.33 yen.
