TOKYO, April 16 (Reuters) - Japanese government bond prices dipped on Monday, while equities gained as investors felt the U.S.-led strikes on Syria over the weekend looked unlikely to escalate for now.
The 10-year JGB yield rose half a basis point to 0.035 percent.
The 20-year yield and 30-year yield each rose half a basis point to 0.505 percent and 0.700 percent, respectively.
Caution ahead of Thursday's 1 trillion yen ($9.32 billion)20-year JGB auction also weighed on the longer-dated maturities.
Japan's Nikkei share average was up 0.25 percent and a rise by S&P 500 e-mini futures pointed to a higher open for Wall Street shares later in the session.
