TOKYO, May 19 (Reuters) - Japanese government bond (JGB) futures rose on Thursday, as investors sought save-haven assets after Wall Street plunged overnight on fears that surging inflation would eat into corporate profits and trigger an economic slowdown.

Benchmark 10-year JGB futures rose 0.05 point to 149.57, with a trading volume of 12,002 lots.

U.S. stock indexes plunged on Wednesday after retailer Target's earnings showed the toll of rising price pressures, sending the benchmark Nikkei share average and other major Asian indexes lower.

The 20-year JGB yield fell 1 basis point to 0.760% and the 30-year JGB yield fell 1 basis point to 1.010%.

The 40-year JGB yield fell 1.5 basis points to 1.125%.

The 10-year JGB yield was flat at 0.240%.

The two-year JGBs did not trade and the yield remained at -0.060%.

The five-year yield was flat at 0.015%. (Reporting by Tokyo markets team)
