TOKYO, Aug 27 (Reuters) - Japan's Nikkei average reversed course in late trade on Friday to climb 1 percent, buoyed after investors unloaded superlong Japanese bonds and bought stocks as well as by hopes of Japanese moves to rein in the strong yen.
But investors remained nervous ahead of U.S. gross domestic product data due out later in the day.
The benchmark Nikkei gained 84.58 points to 8,991.06, climbing further from a 16-month low hit earlier this week. It had started the day down more than 1 percent.
The broader Topix rose 1 percent to 819.62. (Reporting by Elaine Lies)
