While the market is supported by the Bank of Japan's massive bond buying programme, few investors are eager to buy JGBs at current levels after bond yields saw a substantial rise globally in the past few weeks.

Ten-year JGB futures fell 0.02 point to 150.83, with a trading volume of 25,407 lots while the 10-year JGB yield rose 0.5 basis point to 0.045 percent.

The two-year JGB yield was flat at minus 0.145 percent while the five-year JGB yield rose 0.5 basis point to minus 0.110 percent.

But the 30-year JGB yield fell 0.5 basis point to 0.745 percent and the 40-year yield dropped 0.5 basis point to 0.885 percent, helped by a fall in Japanese shares.

The Nikkei share average extended losses into a third day, falling 2.5 percent during this period.
