The 10-year JGB yield rose half a basis point to 0.025 percent. The yield on Tuesday had fallen to zero percent, the lowest since September 2017, when risk aversion gripped the broader markets and sent global equities on a tumble.

The 30-year yield was up 2 basis points at 0.730 percent .

The Bank of Japan on Thursday offered to buy 680 billion yen  ($6.13 billion) of five- to 40-year JGBs in a regular debt-purchasing operation.

Bond buying by the BOJ, however, was not enough to prop up JGBs as Japan's Nikkei soared more than 4 percent following a sharp overnight rebound on Wall Street, weakening investor demand for safe-haven debt.

A retreat by U.S. Treasury prices in the wake of Wall Street's big bounce and a poorly received five-year debt auction also weighed on JGBs.
