JGB futures slip, dented by Nikkei's rise

May 18 (Reuters) - The lead June 10-year Japanese government bond (JGB) futures contract slipped on Friday, pressured by a rise in Tokyo shares to 3-1/2-month highs, as well as weakness in U.S. Treasuries.

The Bank of Japan's offer on Friday to buy medium- and long-term bonds helped limit losses in JGB futures, market participants said.

June 10-year JGB futures eased 0.02 point to 150.67 .

Short-term players were cited as selling long-term and super-long JGBs, with the benchmark 10-year JGB yield inching up 0.5 basis point to 0.060 percent.

Prices of U.S. 10-year Treasuries fell in Friday's Asian trading, pushing their yields to seven-year highs. The U.S. 10-year Treasury yield rose to 3.128 percent at one point, the highest since July 2011, and last stood near 3.122 percent .
