TOKYO, Aug 30 (Reuters) - Japanese government bond yields pulled back from four-month lows on Wednesday as risk aversion that stemmed from the latest bout of tensions over the Korean Peninsula has eased for a while.
The benchmark 10-year JGB yield was 0.5 basis point higher at 0.005 percent after touching zero percent on Tuesday, its lowest since April.
The five-year yield was 1 basis point higher at minus 0.135 percent following a descent to a 3-1/2-month trough of minus 0.145 percent on Tuesday.
JGB yields declined on Tuesday after North Korea launched a ballistic missile over Japan and fueled investor demand for safe-haven debt.
The rise in JGB yields on Wednesday was limited after the Bank of Japan conducted a regular debt-buying operation, purchasing 710 billion yen ($6.47 billion) of five- to 40-year JGBs.
