But longer-dated bonds gave in to profit-taking as domestic stock prices rebounded, resulting in a steepening of the yield curve.
Benchmark 10-year JGB futures rose 0.09 point to 152.86 while the yield on the benchmark 10-year cash JGBs fell 0.5 basis point to minus 0.065pc, the lowest level in almost two months.
The five-year JGB yield fell 1 basis point to minus 0.165pc, also hitting a two-month low, while the two-year yield fell 1 basis point to minus 0.160pc.
Short-term paper was also helped by firm results of the two-year JGB auction on Thursday.
On the other hand, long-dated bonds stepped back from recent rallies as stock prices bounced back on strong earnings from some Japanese companies.
The 20-year JGB yield rose 0.5 basis point to 0.230pc, while the 30-year JGB yield rose 1 basis point to 0.365pc.
However, on a monthly basis, the 20-year yield posted its first fall in five months.
