TOKYO: Japanese government bond yields eased back from recent highs on Friday but remained on course for a substantial weekly advance as the embattled yen fuelled bets for near-term policy tightening by the Bank of Japan.

The 30-year JGB yield retreated 1 basis point (bp) to 2.265% as of 0452 GMT, after reaching a 14-year peak of 2.29% on Thursday. That puts it 12 bps higher for the week.
