Share prices on the Tokyo Stock Exchange will likely edge up this week, spurred by the surprise U.S. credit easing and the yen's weakness against the dollar.

The upside, however, will be limited due to selling by Japanese firms to unwind cross-shareholdings ahead of annual account settlements in March.

The benchmark 225-issue Nikkei Stock Average is expected to move between 13,300 and 14,300 this week, after closing at 13,867.61 Friday, up from 13,785.69 a week earlier.
