TOKYO, Oct 22 (Reuters) - Japan's Nikkei average fell 0.6 percent on Thursday, with stocks hit across the board after U.S. financial shares fell after a warning from a banking analyst and as wariness grew ahead of Japanese earnings. Japan Airlines Corp snapped this week's rising streak to drop 3.2 percent after a newspaper reported that the struggling carrier's net loss may balloon to as much as about $5.5 billion for the year ending in March. The benchmark Nikkei shed 66.22 points to 10,267.17, paring losses that took it down as much as 1.7 percent at one point. The broader Topix fell 0.6 percent to 908.60.
