TOKYO, May 16 (Reuters) - Japan's Nikkei share average edged up on Tuesday, drawing support from a sagging yen and a rise in U.S. shares to record highs.
The Nikkei ended the day 0.25 percent higher at 19,919.82. It earlier rose to 19,998.49, its highest since December 2015, in an initial reaction to overnight Wall Street gains. But the index lost traction as the yen recovered some of its losses.
The broader Topix added 0.27 percent to 1,584.23 and the JPX-Nikkei Index 400 rose 0.22 percent to 14,143.97.
