The 10-year JGB futures were unchanged at 150.69, with a trading volume of 22,401 lots.

Lead 10-year cash JGB yield stood flat at 0.120 percent.

The super-long sector outperformed, with the 20-year , the 30-year and the 40-year JGB yields falling half a basis point each to 0.660 percent, 0.885 percent and 1.045 percent, respectively.

The BOJ's bond buyings in maturities from 10 to 40 years, which attracted limited selling interest among market players, supported sentiment.
