TOKYO: Longer-dated Japanese government bond yields declined on Tuesday following a smooth auction of about 900 billion yen ($8.23 billion) of 30-year debt.

Yields on 20-year paper declined 1 basis point to 0.445%.
The bid-to-cover ratio rose to 3.39 at Tuesday's sale, up from 3.12 at the previous tender of 30-year JGBs on May 13.
Trading was subdued again like Monday, with five-year securities untraded as of 0525 GMT.
The 10-year JGB yield was flat at 0.075%, and the two-year yield was also unchanged at minus 0.125%.
Benchmark 10-year JGB futures rose 0.07 point to 151.61, with a trading volume of 26,730 lots.
"Since the US nonfarm payrolls report, volatility in US rates has dropped, leading to a heightened sense of stasis in the Japanese bond market," said Ataru Okumura, a strategist at SMBC Nikko Securities.
