TOKYO, Oct 23 (Reuters) - Japan's Nikkei stock average edged up 0.2 percent on Friday, with construction machinery shares rising on hopes for China's economy and Kirin Holdings (2503.T) gaining ground on a brokerage upgrade.

But Japan Airlines (9205.T) fell nearly 7 percent, weighing on the benchmark, after the Nikkei business daily reported some creditors have asked the struggling carrier to reduce its capital. [ID:nTFA006470]

The benchmark Nikkei .N225 gained 15.82 points to 10,282.99 and rose only 0.2 percent on the week, with investors locking in profits before Japan's earning season moves into high gear next week.

The broader Topix , which is not as tech-heavy, lost 0.7 percent to 902.03. (Reporting by Elaine Lies)
