TOKYO, Aug 22 (Reuters) - Japan's Nikkei edged up on Monday, but gains were limited as investors were cautiously focused on this week's meeting of global central bankers in Jackson Hole, Wyoming, where the U.S. Federal Reserve may provide insight on the rate outlook.
The Nikkei share average rose 0.3 percent to 16,598.19.
The broader Topix gained 0.6 percent to 1,303.68 and the JPX-Nikkei Index 400 added 0.5 percent to 11,715.58.
